Cadence Tutorial - Layout

Example: CMOS Inverter Layout Covering Contacts with Metal-1

Active contacts in fact only define holes in the oxide (connection terminals). The actual connection to the corresponding diffusion region is made by the Metal layer.

1. Select layer Metal-1 from the LSW

2. Draw two rectangles 1.2u wide to cover the contacts

Note that Metal-1 has to extend over the contact in all directions by at least 0.3u (1 lambda).
