摘要: A method is disclosed for the improvement of BiCMOS or CMOS manufactured device performance, specifically bipolar junction transistor performance, in a cost effective manner. The method provides for fewer masking operations during bipolar junction transistor formation, in a CMOS flow process, yet also provides for the bipolar junction transistor to be optimized.
