Question

What is butting contact and buried contact?

Answer 1

junctions, in silicon-gate integrated circuits. With this method – requiring an additional masking layer – it was possible to use the polysilicon as an additional layer of interconnection, greatly improving the circuit density, particularly in random logic circut Semiconductor to test the critical parameters of devices built using the
silicon gate technology .
The device marked D is a polysilicon to silicon diode and the device marked R11 is a resistor whose connections are made with polysilicon to silicon contacts. The red outline is intended to more clearly illustrate the polysilicon to silicon contact
