Abstract

A short-channel metal oxide semiconductor varactor may include a source region of a first polarity having a source via contact. The varactor may further include a drain region of the first polarity having a drain via contact. The varactor may further include a channel region of the first polarity between the source region and the drain region. The channel region may include a gate. The varactor may further include at least one self-aligned contact (SAC) on the gate and between the source via contact and the drain via contact.
