Abstract

A method of forming of biological sensing structures including a portion of a substrate is recessed to form a plurality of mesas in the substrate. Each of the plurality of mesas has a top surface and a sidewall surface. A first light reflecting layer is deposited over the top surface and the sidewall surface of each mesa. A filling material is formed over a first portion of the first light reflecting layer. A stop layer is deposited over the filling material and a second portion of the first light reflecting layer. A sacrificial layer is formed over the stop layer and is planarized exposing the stop layer. A first opening is formed in the stop layer and the first light reflecting layer. A second light reflecting layer is deposited over the first opening. A second opening is formed in the second light reflecting layer.
