    摘要: A manufacturing method of a SiGe HBT is disclosed. Alter an emitter region is formed, an ion implantation is performed with a tilt angle to a base region by using an extrinsic base ion implantation process; boron ions are implanted during the extrinsic base ion implantation with an implantation dose from 1e15 to 1e16 cm−2, an implantation energy from 5 to 30 KeV, and a tilt angle from 5 to 30 degrees. The tilt angle enables the implantation of P-type impurities into the part of the intrinsic base region at the bottom of the emitter window dielectric layer as well as the extrinsic base region, so that the base region excluding the part of the intrinsic base region in contact with the emitter region is entirely doped with P-type impurities, thus reducing the base resistance and improving the frequency characteristic of a transistor without needing to reduce its size.

    摘要: This invention disclosed a manufacturing approach of collector and buried layer of a bipolar transistor. One aspect of the invention is that a pseudo buried layer, i.e, collector buried layer, is manufactured by ion implantation and thermal anneal. This pseudo buried layer has a small area, which makes deep trench isolation to divide pseudo buried layer unnecessary in subsequent process. Another aspect is, the doped area, i.e, collector, is formed by ion implantation instead of high cost epitaxy process. This invention simplified the manufacturing process, as a consequence, saved manufacturing cost.

    摘要: A PN-junction varactor in a BiCMOS process is disclosed which comprises an N-type region, a P-type region and N-type pseudo buried layers. Both of the N-type and P-type regions are formed in an active area and contact with each other, forming a PN-junction; the P-type region is situated on top of the N-type region. The N-type pseudo buried layers are formed at bottom of shallow trench field oxide regions on both sides of the active area and contact with the N-type region; deep hole contacts are formed on top of the N-type pseudo buried layers in the shallow trench field oxide regions to pick up the N-type region. A manufacturing method of PN-junction varactor in a BiCMOS process is also disclosed.
