Among other things, one or more support structures for integrated circuitry and techniques for forming such support structures are provided. A support structure comprises one or more trench structures, such as a first trench structure and a second trench structure formed around a periphery of integrated circuitry. In some embodiments, one or more trench structures are formed according to partial substrate etching, such that respective trench structures are formed into a region of a substrate. In some embodiments, one or more trench structures are formed according to discontinued substrate etching, such that respective trench structures comprise one or more trench portions separated by separation regions of the substrate. The support structure mitigates stress energy from reaching the integrated circuitry, and facilitates process-induced charge release from the integrated circuitry.

The presented principles describe an apparatus and method of making the same, the apparatus being a semiconductor circuit device, having shallow trench isolation features bounding an active area and a periphery area on a semiconductor substrate to electrically isolate structures in the active area from structures in the periphery area. The shallow trench isolation feature bounding the active area is shallower than the shallow trench isolation feature bounding the periphery area, with the periphery area shallow trench isolation structure being formed through two or more etching steps.
