Abstract: A metal-oxide-semiconductor (MOS) device for radio frequency (RF) applications may include a guard ring. The guard ring may surround the MOS device and at least one other MOS device. The MOS device may further include a level zero contact layer coupled to a first interconnect layer through level zero interconnects and vias. The first interconnect layer may be for routing to the MOS device.

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.
