  • Patent number: 10047440
    Abstract: The present disclosure generally relates to an improved method for forming low resistivity crystalline silicon films for display devices. The processing chamber in which the low resistivity crystalline silicon film is formed is pressurized to a predetermined pressure and a radio frequency power at a predetermined power level is delivered to the processing chamber. In addition, feeding locations of one or more VHF power generator and controlling of each VHF power generator via phase modulation and sweeping allows for plasma uniformity improvements by compensating for the non-uniformity of the thin film patterns produced by the chamber, due to the standing wave effect. Diffuser plate having two curved surfaces helps improve crystallinity uniformity.

  • Patent number: 9950924
    Abstract: A method for fabricating an integrated MEMS-CMOS device uses a micro-fabrication process that realizes moving mechanical structures (MEMS) on top of a conventional CMOS structure by bonding a mechanical structural wafer on top of the CMOS and etching the mechanical layer using plasma etching processes, such as Deep Reactive Ion Etching (DRIE). During etching of the mechanical layer, CMOS devices that are directly connected to the mechanical layer are exposed to plasma. This sometimes causes permanent damage to CMOS circuits and is termed Plasma Induced Damage (PID). Embodiments of the present invention presents methods and structures to prevent or reduce this PID and protect the underlying CMOS circuits by grounding and providing an alternate path for the CMOS circuits until the MEMS layer is completely etched.
