Cell structure for bipolar integrated circuits and method

摘要

In one embodiment, a bipolar cell (31) includes a cell boundary (32) that defines a cell active area (33), a first array of bipolar transistors (41) is formed within the cell active area (33) and configured for a first function. The bipolar transistors (42) within the first array (41) are parallel to each other. The bipolar cell (31) further includes a second array of bipolar transistors (61) formed within the cell active area (33) and configured for a second function that is different than the first function. The bipolar transistors (62) within the second array (61) are parallel to each other and oriented in a different direction than the transistors (42) in the first array (41).
