WebVLSI MCQ Set 1 1. Diffusion and polysilicon layers are connected together using a) butting contact b) buried contact c) separate contact d) cannot be connected 2. Which is more complex process? a) buried contact b) butting contact c) buried & butting contact d) none of the mentioned 3. Which contact cut occupies smaller area?… WebThe process is more complex for connecting diffusion to poly-silicon using the butting contact approach (Fig.b), In effect, a 2. x 2 contact cut is made down to each of the layers to be joined. The layers are butted together in such a way that these two contact cuts become contiguous.
