Protecting Tape-Out and GDSII Data When Outsourcing Chip Fabrication in Vietnam: Foundry NDAs usually arises against the background where a chip design company is about to send tape-out data and GDSII files containing the entire circuit design to a fabrication plant, the moment its most valuable IP leaves internal control systems.
The analysis below walks through the legal framework in force on 20 October 2026, how that framework applies to protecting tape-out and GDSII data when outsourcing chip fabrication, a safe implementation sequence and the risks investors typically discover only once protecting tape-out and GDSII data when outsourcing chip fabrication has reached its completion stage.
The legal framework governing protecting tape-out and GDSII data when outsourcing chip fabrication
The legal ground for protecting tape-out and GDSII data when outsourcing chip fabrication is the Law on Intellectual Property No. 50/2005/QH11 through its 2009, 2019 and 2022 amendments and the amendment by Law 131/2025/QH15, implemented with Decree 65/2023/ND-CP, and on that ground the principle to hold is that chip design data, before any layout-design filing, is protected only by trade-secret mechanisms and confidentiality contracts, so the foundry NDA must precisely define the data handed over, ban copying and use beyond the order, require destruction or return of data after production and carry deterrent-level liability A quick test for protecting tape-out and GDSII data when outsourcing chip fabrication is placing the draft document beside the current licence and asking what in the issue of how is a design kept confidential when outsourcing chip fabrication that licence does not yet cover, because every gap will be pointed out by the receiving authority.
The Civil Code No. 91/2015/QH13 protects freedom of commitment and agreement (Article 3) and regulates breach penalties (Article 418) and damages for breach of contract (Article 419), and these provisions are the legal footing of protecting tape-out and GDSII data when outsourcing chip fabrication where a chip design company is about to send tape-out data and GDSII files containing the entire circuit design to a fabrication plant, the moment its most valuable IP leaves internal control systems Partners and banks usually read protecting tape-out and GDSII data when outsourcing chip fabrication through their own lens before the state authority does, and their first question almost always circles around what clauses must the non-disclosure agreement (NDA) with the foundry contain, so a written answer prepared in advance is not optional.
The transfer framework in Articles 138 to 149 of the Law on Intellectual Property sets two form requirements for protecting tape-out and GDSII data when outsourcing chip fabrication: the ownership assignment contract must be in writing, and registration with the IP authority decides when the right truly changes hands in the cases prescribed by law, from which it follows that sending GDSII over ordinary channels and letting the foundry keep it indefinitely for convenient re-runs leaves the design outside the owner’s control for years, and when a leak occurs the company has no access log to prove the source in court When preparing the file for protecting tape-out and GDSII data when outsourcing chip fabrication, the company should test this point against the issue of what should be done if the design data leaks from the outset, because waiting for the receiving authority to request supplements usually delays protecting tape-out and GDSII data when outsourcing chip fabrication by weeks against plan.
Analysing the questions investors ask around protecting tape-out and GDSII data when outsourcing chip fabrication
On the question of how is a design kept confidential when outsourcing chip fabrication, what the investor needs is a conclusion immediately applicable to protecting tape-out and GDSII data when outsourcing chip fabrication rather than a general principle, and that conclusion must rest on the original instruments in force, not on oral summaries passed between project teams. Answering the question of what clauses must the non-disclosure agreement (NDA) with the foundry contain correctly starts from the company’s own registration documents in protecting tape-out and GDSII data when outsourcing chip fabrication, because the same question put to two different registration files receives two different procedural answers.
The question of what should be done if the design data leaks is where the hidden cost of protecting tape-out and GDSII data when outsourcing chip fabrication usually sits, because handling it superficially spawns another round of registration amendments and explanations that no project team budgeted for at the start. Analysing the question of under what controlled-sharing mechanism is data given to the foundry requires separating what the law states clearly from what still depends on the local handling authority’s practice, because mixing the two is the source of most wrong decisions around protecting tape-out and GDSII data when outsourcing chip fabrication.
An illustration shows the mechanism of protecting tape-out and GDSII data when outsourcing chip fabrication clearly: the company starts while the original file is not yet locked, and the consequence appears almost immediately because sending GDSII over ordinary channels and letting the foundry keep it indefinitely for convenient re-runs leaves the design outside the owner’s control for years, and when a leak occurs the company has no access log to prove the source in court.
A safe implementation sequence for protecting tape-out and GDSII data when outsourcing chip fabrication
- Delimit the whole foundation file of protecting tape-out and GDSII data when outsourcing chip fabrication: original contracts, licences, internal minutes and obligations not yet closed, marking which documents lack signatures, lack registration or have expired.
- Identify the competent authority for each workstream of protecting tape-out and GDSII data when outsourcing chip fabrication and build a dependency schedule, which item must finish before which, instead of filing everything at once and being sent back piecemeal.
- Turn the questions clients stumble on most around protecting tape-out and GDSII data when outsourcing chip fabrication, especially what should be done if the design data leaks, into a decision list to be locked by resolution or written agreement before the implementation date.
- Complete the registration changes that protecting tape-out and GDSII data when outsourcing chip fabrication drags with it, cross-checking particulars across the business registry, investment authority, tax authority and bank so no discrepancy remains in name, address or representative.
- Close the protecting tape-out and GDSII data when outsourcing chip fabrication file with a handover list stating what is done, what is still open and who owns each open item, avoiding an organisation-wide assumption that everything ended while one obligation stays live.
Risks to anticipate in protecting tape-out and GDSII data when outsourcing chip fabrication
The most distinctive risk of protecting tape-out and GDSII data when outsourcing chip fabrication lies in the following point. Sending GDSII over ordinary channels and letting the foundry keep it indefinitely for convenient re-runs leaves the design outside the owner’s control for years, and when a leak occurs the company has no access log to prove the source in court. The second risk of protecting tape-out and GDSII data when outsourcing chip fabrication rarely sits in the documents the parties sign with each other but in the state obligations running underneath in parallel, such as tax finalisation, the labour plan or licence adjustments, and it is that layer that returns as back-tax or penalties after protecting tape-out and GDSII data when outsourcing chip fabrication has closed. A third risk attached to protecting tape-out and GDSII data when outsourcing chip fabrication arises from the issue of what clauses must the non-disclosure agreement (NDA) with the foundry contain: when the parties do not fix the handling in writing beforehand, each reads it in its own favour and the conflict erupts exactly when protecting tape-out and GDSII data when outsourcing chip fabrication no longer has a way back.
protecting tape-out and GDSII data when outsourcing chip fabrication does not end on the signing date or the date an amended certificate issues, but only when the last tax, labour and reporting duty arising from it has been closed with vouchers. The investor should therefore keep one accountable owner for protecting tape-out and GDSII data when outsourcing chip fabrication until that final closing point is confirmed, instead of disbanding the project team right after formal completion.
Frequently asked questions: protecting tape-out and GDSII data when outsourcing chip fabrication
How is a design kept confidential when outsourcing chip fabrication?
On the question of how is a design kept confidential when outsourcing chip fabrication, practice in Vietnam shows the outcome of protecting tape-out and GDSII data when outsourcing chip fabrication depends more on the quality of preparation before filing than on filing speed, because a file consistent across the relevant authorities is rarely sent back for amendment. More specifically, chip design data, before any layout-design filing, is protected only by trade-secret mechanisms and confidentiality contracts, so the foundry NDA must precisely define the data handed over, ban copying and use beyond the order, require destruction or return of data after production and carry deterrent-level liability.
What clauses must the non-disclosure agreement (NDA) with the foundry contain?
The question of what clauses must the non-disclosure agreement (NDA) with the foundry contain must be answered against the specific position of protecting tape-out and GDSII data when outsourcing chip fabrication: the company should check its charter, licences and compliance history together before choosing an option, rather than deciding on a single factor. More specifically, a chip design company is about to send tape-out data and GDSII files containing the entire circuit design to a fabrication plant, the moment its most valuable IP leaves internal control systems.
What should be done if the design data leaks?
For the question of what should be done if the design data leaks, the safe principle for protecting tape-out and GDSII data when outsourcing chip fabrication is not to commit towards a third party before the legal basis and the handling plan are locked in writing, because an oral commitment is worth almost nothing once a dispute arises. More specifically, sending GDSII over ordinary channels and letting the foundry keep it indefinitely for convenient re-runs leaves the design outside the owner’s control for years, and when a leak occurs the company has no access log to prove the source in court.
Under what controlled-sharing mechanism is data given to the foundry?
On the question of under what controlled-sharing mechanism is data given to the foundry, the first thing to clarify for protecting tape-out and GDSII data when outsourcing chip fabrication is whether it belongs to the basis layer, the file layer or the sequence layer, because each layer needs a different kind of evidence to answer and carries a different risk if answered wrongly. More specifically, procedurally, the company must close out the whole file chain of protecting tape-out and GDSII data when outsourcing chip fabrication, from the written agreement and registration with the competent authority to document retention, because a single missing link is enough to have the entire plan sent back to the start.
