Method for fabricating a self-aligned bipolar transistor with planarizing layer and related structure










Image Number 5 for United States Patent #6809353.

According to one exemplary embodiment, a bipolar transistor comprises a base having a top surface. The bipolar transistor further comprises first and second link spacers situated on the top surface of the base. The bipolar transistor further comprises a sacrificial post situated on the top surface of the base between the first and second link spacers. The first and second link spacers may have a height, for example, approximately equal to or, in another embodiment, substantially less than a height of the sacrificial post. According to this exemplary embodiment, the bipolar transistor further comprises a non-sacrificial planarizing layer situated over the sacrificial post, first and second link spacers, and base. The non-sacrificial planarizing layer may comprise, for example, silicate glass. The sacrificial planarizing layer may have a height, for example, approximately equal to or, in another embodiment, greater than greater than a height of the first and second link spacers.
