Title: Semiconductor device
Inventor: KAJITA TATSUYA
IPC: H01L29/792
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a semiconductor device, in which the prevention of the deterioration of the gate oxide film of a floating gate field-effect transistor and its operation at high speed are made compatible with each other, by selecting a material for the gate electrode of the floating-gate field-effect transistor different from that of the gate electrode of a peripheral element. CONSTITUTION:The gate of a memory transistor A is formed in layers in the order of a first gate oxide film 4, a floating gate electrode 11, a second gate oxide film 47 and a control gate electrode 12 from a lower section. Since the control gate electrode 12 among them is composed only of polysilicon and a high melting-point metallic silicide is not superposed, the possibility of the deterioration of the second gate oxide film 47 due to surface stress is prevented. On the other hand, sections except the gate electrode section of the memory transistor A that is, a wiring section and the gate of a peripheral transistor B, are shaped in layers in the order of the first gate oxide film 4 and a gate electrode 1B from a lower section. Since the gate electrode 1B between them is formed in structure in which WSi2 13 is superposed to polysilicon 12, the resistance of a current path is lowered, thus increasing the working speed of an element. Accordingly, a semiconductor device in which the prevention of the deterioration of the gate oxide film of a floating-gate field-effect transistor and operation at high speed are made to coexist is acquired.
