  • Patent number: 11955476
    Abstract: A low cost IC solution is disclosed to provide Super CMOS microelectronics macros. Hereinafter, the Super CMOS or Schottky CMOS all refer to SCMOS. The SCMOS device solutions with a niche circuit element, the complementary low threshold Schottky barrier diode pairs (SBD) made by selected metal barrier contacts (Co/Ti) to P— and N—Si beds of the CMOS transistors. A DTL like new circuit topology and designed wide contents of broad product libraries, which used the integrated SBD and transistors (BJT, CMOS, and Flash versions) as basic components. The macros include diodes that are selectively attached to the diffusion bed of the transistors, configuring them to form generic logic gates, memory cores, and analog functional blocks from simple to the complicated, from discrete components to all grades of VLSI chips. Solar photon voltaic electricity conversion and bio-lab-on-a-chip are two newly extended fields of the SCMOS IC applications.
