Merged source/drain and gate contacts in SRAM bitcell
Abstract:
A method of forming a semiconductor device with uniform regular shaped gate contacts and the resulting device are disclosed. Embodiments include forming first and second gate electrodes adjacent one another on a substrate; forming at least one trench silicide (TS) on the substrate between the first and second gate electrodes; forming a gate contact on the first gate electrode, the gate contact having a regular shape; forming a source/drain contact on a trench silicide between the first and second gate electrodes, wherein an upper portion of the source/drain contact overlaps an upper portion of the gate contact.
