    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: A far subcollector, or a buried doped semiconductor layer located at a depth that exceeds the range of conventional ion implantation, is formed by ion implantation of dopants into a region of an initial semiconductor substrate followed by an epitaxial growth of semiconductor material. A reachthrough region to the far subcollector is formed by outdiffusing a dopant from a doped material layer deposited in the at least one deep trench that adjoins the far subcollector. The reachthrough region may be formed surrounding the at least one deep trench or only on one side of the at least one deep trench. If the inside of the at least one trench is electrically connected to the reachthrough region, a metal contact may be formed on the doped fill material within the at least one trench. If not, a metal contact is formed on a secondary reachthrough region that contacts the reachthrough region.

    摘要: Methods are disclosed for forming a varied impurity profile for a collector using scattered ions while simultaneously forming a subcollector. In one embodiment, the invention includes: providing a substrate; forming a mask layer on the substrate including a first opening having a first dimension; and substantially simultaneously forming through the first opening a first impurity region at a first depth in the substrate (subcollector) and a second impurity region at a second depth different than the first depth in the substrate. The breakdown voltage of a device can be controlled by the size of the first dimension, i.e., the distance of first opening to an active region of the device. Numerous different sized openings can be used to provide devices with different breakdown voltages using a single mask and single implant. A semiconductor device is also disclosed.
