VIAs in VLSI

What are VIAs in VLSI? To connect between different metal layers, we need poly layer along with the metal layers that we are going to connect. These are basically called as VIAs. From the below picture we can see that…

Pitch, Spacing & Offset

Pitch The distance between the center to center of the metal is called as pitch. In the below picture, B is pitch. Spacing Spacing is the distance between the edge to edge metal layers. The distance A is spacing in…
