Abstract
A method of forming an electrical contact in a semiconductor structure includes performing a patterning process to form a hard mask on a semiconductor structure comprising a first semiconductor region, a second semiconductor region, a dielectric layer having a first opening over the first semiconductor region and a second opening over the second semiconductor region, wherein the hard mask covers an exposed surface of the first semiconductor region within the first opening, performing a first selective deposition process to form a contact layer on the exposed surface of the second semiconductor region within the second opening, and performing a second selective deposition process to form a cap layer on the contact layer.
