Assembly, testing and packaging (ATP) is Vietnam’s most realistic foothold in the semiconductor chain: capital intensity far below a wafer fab, but technology discipline at a level where one weak confidentiality clause can cost a global customer. An ATP BCC with a Vietnamese partner must solve three problems at once — who buys the machines, how process secrets are kept, and who stands behind export standard commitments to customers in the United States and Europe.
Who invests in ATP equipment: the decision that shapes the whole structure
Packaging and testing equipment has a short technology life and low salvage value outside the semiconductor chain, so the party funding the machines usually demands matching operational control. Two models are common: the foreign party contributes equipment as its BCC capital and keeps ownership, while the Vietnamese partner contributes a cleanroom-standard plant, technical labour and the procedures interface; or the Vietnamese partner buys equipment to the foreign party’s specification against a capacity off-take commitment that recovers the investment. The second model stands only if the minimum volume commitment and off-take term match the machines’ depreciation period; otherwise the Vietnamese partner carries dedicated assets unusable for other customers. Imported equipment needs a consistent customs and tax treatment from the BCC’s investment registration filing under Investment Law 143/2025/QH15, so project assets are not left with legally mixed title between the parties.
Protecting chip technology secrets: structure, not just an NDA
Trade secrets are protected under the Intellectual Property Law where the owner applies necessary secrecy measures — which is why practical measures matter as much as contract clauses. Inside an ATP plant the layers are: zoned access by process step; keeping test programming and the most sensitive parameters on the foreign party’s systems instead of handing everything over; access logs for design data; personal confidentiality undertakings from every engineer with access; and a destruction protocol for scrap containing test chips. Global semiconductor customers typically audit the plant against their own security standards before placing orders; the BCC should write the end customer’s audit right into the contract so the Vietnamese partner knows the obligation in advance, instead of being surprised at the supplier qualification round.
Export standards to the US and export controls: whose commitment is it
Post-ATP products exported onward must meet both customer quality requirements and the destination country’s export control rules for technology goods — compliance duties rest with the exporting party of record and the design owner, allocated per shipment and per market inside the BCC. The contract needs a screening mechanism for sensitive customers and end uses, a stop-shipment clause when control policy changes, and an allocation of cost when an order is cancelled for legal reasons beyond both parties’ control. Vietnam has issued its Semiconductor Industry Development Strategy to 2030, vision to 2050 (Decision 1017/QD-TTg of 2024), so ATP projects should also be checked against investment incentive conditions for high-technology fields at project preparation stage, rather than retrofitted after the plant is already operating.
Frequently asked questions
1. In an ATP cooperation with a Vietnamese partner, who invests in the machinery?
One of two models: the foreign party contributes equipment and keeps ownership while the Vietnamese partner contributes the plant and labour; or the Vietnamese partner buys machines against a capacity off-take commitment matched to the depreciation period. The deciding point is that dedicated assets have low salvage value, so the machine buyer needs volume assurance.
2. How are chip technology secrets protected?
In layers: a secrets inventory and zoned access, test programming kept on the foreign party’s systems, personal confidentiality undertakings for engineers, access logging and a scrap destruction protocol. The Intellectual Property Law protects trade secrets only where the owner has applied necessary secrecy measures.
3. Who guarantees export standards to the United States?
The exporter of record and the design owner share the duties as allocated in the BCC per market: destination export control compliance, screening of customers and end uses, and a stop-shipment mechanism when policy changes.
4. Can a semiconductor BCC obtain investment incentives?
The semiconductor industry is a prioritized direction under Vietnam’s Semiconductor Industry Development Strategy to 2030 (Decision 1017/QD-TTg). The specific incentive level must be checked against location, scale and sector conditions at the time the BCC project is registered.
5. Do foreign customers have audit rights over the ATP plant?
Yes, if the BCC and the supply contracts record that right — and in practice global semiconductor customers always require security and quality audits before placing orders. Recording the audit right in advance lets the Vietnamese partner build its systems rather than face surprise assessments.
