HETEROGENEOUS INTEGRATED CIRCUIT

원문 (중국어)

Aspects of the present disclosure relate to a 3D-millimeter wave integrated circuit (3D-mmWIC configured to improve the efficiency and functionality of radio-frequency (RF) circuits through a multi-material, multi-layered architecture. These aspects can integrate silicon-based complementary metal-oxide semiconductor (CMOS) technology with other semiconductor materials, including Gallium Nitride (GaN), graphene, and/or various semiconductor alloys from the periodic table's Groups II-VI and/or III-V. The 3D-mmWIC can employ a layered structure comprising a silicon substrate, interleaved dielectric layers with embedded metal regions of varying thicknesses and lengths, a semiconductor layer, and/or additional oxide and dielectric layers. This architecture can enable the integration of multiple source, drain, and gate modules, interconnected via a sophisticated metal/oxide network. The disclosed integrated circuit architecture can provide significant advancements in RF circuit integration, offering reductions in size and cost while increasing design flexibility and performance.
