摘要

This paper presents a technique for the fabrication of complementary bipolar circuits by the bonding of pre-processed wafers. Bonding of patterned buried layers allows the various long diffusions that are associated with well and sinker drives to be de-coupled from the buried layers allowing for the fabrication of high performance and/or high voltage devices. Bonding of patterned buried layers presents many problems, principally non-planar and chemically reactive surfaces. These can result in voids. In this paper we overcome these issues and present a process, which has been used to manufacture commercially available CBIC devices.
