A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.

Semiconductor structure having asymmetric source/drain regions

A semiconductor structure includes a gate structure, a source region, a drain region, and an isolation structure. The gate structure includes a first portion, a second portion and a third portion. The first portion extends in a first direction, and the second portion and the third portion extend in a second direction.

Semiconductor device with guard ring coupled resonant circuit

An isolation structure in a semiconductor device absorbs electronic noise and prevents substrate leakage currents from reaching other devices and signals. The isolation structure provides a duality of deep N-well ('DNW') isolation structures surrounding an RF device or other source of electronic noise. The DNW isolation structures extend into the substrate at a depth of at least about 2.5 &#x3bc;m and may be coupled to V. P+ guard rings are also provided in some embodiments and are provided inside, outside or between the dual DNW isolation structures.
