Abstract: A through silicon via (TSV) and a deep trench capacitor (DTCap) or a deep trench isolation (DTI) are simultaneously formed on the same substrate by a single mask and a single reactive ion etching (RIE). The TSV trench is wider and deeper that the DTCap or DTI trench. The TSV and DTCap or DTI are formed with different dielectric materials on the trench sidewalls. The TSV and DTCap or DTI are perfectly aligned.

Abstract: A modularized capacitor array includes a plurality of capacitor modules. Each capacitor module includes a capacitor and a switching device that is configured to electrically disconnect the capacitor. The switching device includes a sensing unit configured to detect the level of leakage of the capacitor so that the switching device disconnects the capacitor electrically if the leakage current exceeds a predetermined level. Each capacitor module can include a single capacitor plate, two capacitor plates, or more than two capacitor plates. The leakage sensors and switching devices are employed to electrically disconnect any capacitor module of the capacitor array that becomes leaky, thereby protecting the capacitor array from excessive electrical leakage.

Abstract: Embodiments of the invention provide a relatively uniform width fin in a Fin Field Effect Transistors (FinFETs) and apparatus and methods for forming the same. A fin structure may be formed such that the surface of a sidewall portion of the fin structure is normal to a first crystallographic direction. Tapered regions at the end of the fin structure may be normal to a second crystal direction. A crystallographic dependent etch may be performed on the fin structure. The crystallographic dependent etch may remove material from portions of the fin normal to the second crystal direction relatively faster, thereby resulting in a relatively uniform width fin structure.

Abstract: Voltage programmable anti-fuse structures and methods are provided that include at least one conductive material island atop a dielectric surface that is located between two adjacent conductive features. In one embodiment, the anti-fuse structure includes a dielectric material having at least two adjacent conductive features embedded therein.

When the anti-fuse structure is in a programmed state, a dielectric breakdown path is present in the dielectric material that is located beneath the at least one conductive material island which conducts electrical current to electrically couple the two adjacent conductive features.

Abstract: A high-density deep trench capacitor array with a plurality of leakage sensors and switch devices. Each capacitor array further comprises a plurality of sub-arrays, wherein the leakage in each sub-array is independently controlled by a sensor and switch unit. The leakage sensor comprises a current mirror, a transimpedance amplifier, a voltage comparator, and a timer. If excessive leakage current is detected, the switch unit will automatically disconnect the leaky capacitor module to reduce stand-by power and improve yield. An optional solid-state resistor can be formed on top of the deep trench capacitor array to increase the temperature and speed up the leakage screening process.

The insulating layer is etched to, at the same time, form at least one void both within the implant region and outside of the implant region, wherein the etch rate through the insulating layer within the implant region is different from an etch rate through the insulating layer outside of the implant region. The void is filled with at least one conductor material to form the feature in the insulating layer.
