Bipolar device having improved capacitance

Abstract:

The invention, in one aspect, provides a semiconductor device that comprises a collector located in a semiconductor substrate and an isolation region located under the collector, wherein a peak dopant concentration of the isolation region is separated from a peak dopant concentration of the collector by at least about 0.9 microns. The invention also provides a method for forming this device.

Abstract(Chinese):

本发明在一个方面提供了一种半导体器件，其包括位于半导体衬底中的集电极和位于集电极下方的隔离区域，其中将隔离区域的峰值掺杂浓度与集电极的峰值掺杂浓度分开，至少约0.9微米。本发明还提供了一种用于形成该装置的方法。
