Abstract:
An example a semiconductor device includes a first circuit (102) and a second circuit (104) formed in a semiconductor substrate (101). The semiconductor device further includes a first guard structure (106-1) formed in the semiconductor substrate and disposed between the first circuit and the second circuit, the first guard structure including first discontinuous pairs of n+ and p+ diffusions (108-1) disposed along a first axis. The semiconductor device further includes a second guard structure (106-2) formed in the semiconductor substrate and disposed between the first circuit and the second circuit, the second guard structure including second discontinuous pairs of n+ and p+ diffusions (108-2) disposed along the first axis, the second discontinuous pairs of n+ and p+ diffusions being staggered with respect to the first discontinuous pairs of n+ and p+ diffusions.
Abstract:
An integrated circuit (100) has a transistor with an active gate structure 108 overlying an active diffusion area 112 formed in a semiconductor substrate 126. A dummy gate structure 110 is formed over a diffusion area and separated from the active gate structure by a selected distance (d2). A stress layer (130) overlying the transistor array produces stress in a channel region (107) of the transistor.
Abstract:
Interconnecting logic provides connectivity of an embedded fixed logic circuit, or circuits, with programmable logic fabric of a programmable gate array such that the fixed logic circuit functions as an extension of the programmable logic fabric. The interconnecting logic includes interconnecting tiles and may further include interfacing logic. The interconnecting tiles provide selective connectivity between inputs and/or outputs of the fixed logic circuit and the interconnects of the programmable logic fabric. The interfacing logic, when included, provides logic circuitry that conditions data transfers between the fixed logic circuit and the programmable logic fabric.
