Title: Fabrication of semiconductor device
Inventor: SAKURAI KOJI
IPC: H01L29/423
Filed: 1991-05-13
Abstract: PURPOSE:To make smooth the step of polycide electrode and to prevent exfoliation of high melting point metal silicide layer constituting the polycide gate electrode. CONSTITUTION:A gate oxide film 2, a poly-Si layer 3 and a tungsten silicide(WSi) layer 4 are formed sequentially on a silicon semiconductor substrate 1 and then the WSi layer 4 and the poly-Si layer 3 are patterned, arsenic ions 5 are implanted at high concentration to render the poly-Si layer 3 low resistive while simultaneously to make the surface of the WSi layer 4 amorphous thus preventing exfoliation of the WSi layer 4 due to abnormal oxidation. A silicon dioxide layer 6 is then formed through CVD method and annealed to render the WSi layer 4 low resistive. Fluorine(F) in the WSi layer 4 is mainly absorbed by the silicon oxide layer 6 having high affinity with F and scarcely dispersed into the poly-Si layer 3 thus preventing the withstand voltage of the gate oxide film 2 from deteriorating. Furthermore, the thickness of the silicon oxide layer 5 is not added to the step of the gate electrode.

Filed: 1982-06-25
Abstract: PURPOSE:To suppress generation of an unnecessary angle modulation component, by inserting limiters of two stages or more between an AM-FM signal generator and a BPF, and also using a multiplication type amplitude modulator.
