Meaning
Semiconductor manufacturing categorises high-density multi-layer stacked silicon architectures as a primary technology class for domestic industry development. Integration of 3d IC designs occurs under the supervision of the Ministry of Industry and Information Technology through the Guidance Catalogue for Industrial Restructuring. Foreign investors seeking to manufacture these multi-tier devices must secure joint venture approvals if the processing density exceeds established regional thresholds.
Stacking Architecture
Vertical interconnection of active silicon dies using through-silicon vias defines the structural limit of these systems. Standard 3d IC assemblies reduce signal latency and footprint but require strict heat dissipation management in high-reliability operations. This layout concentrates thermal loads across several microscopic boundaries.
Encouraged Classification
The Catalogue of Industries for Encouraging Foreign Investment includes advanced electronic packaging as an eligible sector for corporate tax reductions. Under this policy, 3d IC packaging plants receive import tariff exemptions on critical cleanroom tooling and measurement instruments. These financial relief measures are administered by the State Administration of Taxation at the provincial level.
Technology Transfer
Export control regulations managed by the Ministry of Commerce restrict the outbound licensing of advanced stacking software and design files. Foreign commercial entities must obtain specific technology export licenses to share design layouts with offshore processing facilities. Failure to secure these administrative clearances leads to immediate suspension of local business operations.
