摘要： Semiconductor methods and device structures for suppressing latch-up in bulk CMOS devices. The method comprises forming a trench in the semiconductor material of the substrate with first sidewalls disposed between a pair of doped wells, also defined in the semiconductor material of the substrate. The method further comprises forming an etch mask in the trench to partially mask the base of the trench, followed by removing the semiconductor material of the substrate exposed across the partially masked base to define narrowed second sidewalls that deepen the trench. The deepened trench is filled with a dielectric material to define a trench isolation region for devices built in the doped wells. The dielectric material filling the deepened extension of the trench enhances latch-up suppression.

摘要： Hybrid substrates characterized by semiconductor islands of different crystal orientations and methods of forming such hybrid substrates. The methods involve using a SIMOX process to form an insulating layer. The insulating layer may divide the islands of at least one of the different crystal orientations into mutually aligned device and body regions. The body regions may be electrically floating relative to the device regions.

摘要： A well isolation trenches for a CMOS device and the method for forming the same. The CMOS device includes (a) a semiconductor substrate, (b) a P well and an N well in the semiconductor substrate, (c) a well isolation region sandwiched between and in direct physical contact with the P well and the N well. The P well comprises a first shallow trench isolation (STI) region, and the N well comprises a second STI region. A bottom surface of the well isolation region is at a lower level than bottom surfaces of the first and second STI regions. When going from top to bottom of the well isolation region, an area of a horizontal cross section of the well isolation region is an essentially continuous function.

摘要： Semiconductor structures and methods for suppressing latch-up in bulk CMOS devices. The semiconductor structure comprises a shaped-modified isolation region that is formed in a trench generally between two doped wells of the substrate in which the bulk CMOS devices are fabricated. The shaped-modified isolation region may comprise a widened dielectric-filled portion of the trench, which may optionally include a nearby damage region, or a narrowed dielectric-filled portion of the trench that partitions a damage region between the two doped wells. Latch-up may also be suppressed by providing a lattice-mismatched layer between the trench base and the dielectric filler in the trench.

摘要： Semiconductor structures and methods for suppressing latch-up in bulk CMOS devices. The semiconductor structure comprises first and second adjacent doped wells formed in the semiconductor material of a substrate. A trench, which includes a base and first sidewalls between the base and the top surface, is defined in the substrate between the first and second doped wells. The trench is partially filled with a conductor material that is electrically coupled with the first and second doped wells. Highly-doped conductive regions may be provided in the semiconductor material bordering the trench at a location adjacent to the conductive material in the trench.
