Bridging advanced semiconductor integration and AI-driven manufacturing intelligence.

Enabling compact RF design through 3D integration and hybrid bonding.

Turning proprietary Fab data into learning-based manufacturing intelligence.
The future of semiconductor competitiveness is no longer defined only by smaller geometries or faster equipment.
It is defined by the ability to manage complexity — in RF architecture, thermal behavior, manufacturing flow, equipment constraints, and human decision-making.
3DMMIC operates at this intersection.
We develop technologies that address semiconductor complexity from two directions: 3D integration for compound semiconductor MMICs, and learning-based manufacturing intelligence for semiconductor Fab operations.

3DMMIC re-architects compound semiconductor MMICs through wafer-level 3D integration.
By separating active and passive functions into vertically integrated wafers, our 3D Solution enables more compact RF layouts, more efficient use of compound semiconductor material, and RF / thermal co-design for next-generation MMIC applications.
3DMMIC develops learning-based AI models for semiconductor shop-floor decision-making.
Our Smart Manufacturing approach transforms proprietary Fab data and experienced human decisions into manufacturing intelligence for dispatching, scheduling, bottleneck management, delivery precision, and productivity improvement.
Compound semiconductor innovation is becoming increasingly complex.
At the device level, RF performance, die size, passive networks, thermal distribution, and manufacturability must be considered together.
At the Fab level, product mix, WIP distribution, equipment constraints, Q-time pressure, bottlenecks, and delivery commitments change continuously.
3DMMIC focuses on practical technologies that help semiconductor companies manage these complexities with engineering discipline and learning-based intelligence.
