    摘要: A method and device providing a HA junction varactor which may be fabricated with a reduced variation in C-V tuning curve from one varactor to the next. The process produces a varactor with an active region formed substantially by doping an Si substrate with various dopants at various energy levels. Accordingly, unit-to-unit device variation is reduced because etching, growing, and deposition processes to make the active portion of the varactor are reduced or eliminated. The resulting HA junction has a more uniform thickness, and a more uniform doping profile.

    摘要: The invention relates to noise isolation in semiconductor devices, and a design structure on which a subject circuit resides. A design structure is embodied in a machine readable medium used in a design process. The design structure includes a deep sub-collector located in a first epitaxial layer, and a doped region located in a second epitaxial layer, which is above the first epitaxial layer. The design structure further includes a reach-through structure penetrating from a surface of the device through the first and second epitaxial layers to the deep sub-collector, and a trench isolation structure penetrating from a surface of the device and surrounding the doped region.

    摘要: A method of fabricating a buried subcollector in which the buried subcollector is implanted to a depth in which during subsequent epi growth the buried subcollector remains substantially below the fictitious interface between the epi layer and the substrate is provided. In particular, the inventive method forms a buried subcollector having an upper surface (i.e., junction) that is located at a depth from about 3000 Å or greater from the upper surface of the semiconductor substrate. This deep buried subcollector having an upper surface that is located at a depth from about 3000 Å or greater from the upper surface of the substrate is formed using a reduced implant energy (as compared to a standard deep implanted subcollector process) at a relative high dose. The present invention also provides a semiconductor structure including the inventive buried subcollector which can be used as cathode for passive devices in high frequency applications.
