The buried isolation layer interfaces with the isolation ring, thereby isolating the first and second circuit areas from a backside bias of the semiconductor substrate.

Abstract: Methods and apparatus are described that reduce the possibility that unintended subway short-circuits will occur between contacts of different potentials along the boundary between tensile and compressive liners (the T-C boundary). This may be done without unduly increasing the size of the semiconductor device, or even increasing the size at all over previous designs. For example, simply by adjusting the layout of the device, the contacts of two different common gates may be offset in opposing directions relative to the T-C boundary. Or, by forming a T-C boundary having a zigzag or other similar pattern, the contacts may be arranged even closer together while still reducing the likelihood of short-circuiting subways forming. Such layout adjustments do not otherwise require any additional steps or cost.
