CMOS Technology at KTH
- The division of Electronics and Embedded Systems at KTH has established a CMOS technology based on fully depleted silicon on insulator (FDSOI) transistors and 3 level metallization.
- The technology includes a fabrication process of CMOS wafers in KTH's Electrum Laboratory and a design kit in Cadence environment.
- The full digital design flow from HDL to GDSII is available using Cadence tools GENUS211 (digital synthesis), INNOVUS181 (digital place & route), XCELIUM1803 (digital simulation), IC618 (Virtuoso Schematic and layout editor) and PVS161 (Design rule check and layout versus schematic physical verification).
- The CMOS technology is open to any academic researchers to design and fabricate integrated circuits.
- In collaborative work, it is possible to adopt the CMOS process to integrate heterogeneous materials/devices for innovative systems.
