Abstract:
A field effect transistor including a source region, a drain region, a channel region extending between the source region and the drain region, a gate on the channel region, a gate contact on the gate at an active region of the gate, a source contact on the source region, a drain contact on the drain region, and recesses in the source and drain contacts substantially aligned with the gate contact. Upper surfaces of the recesses in the source and drain contacts are spaced below an upper surface of the gate by a depth.
