    摘要: A method includes bonding a first bond layer to a second bond layer through eutectic bonding. The step of bonding includes heating the first bond layer and the second bond layer to a temperature higher than a eutectic temperature of the first bond layer and the second bond layer, and performing a pumping cycle. The pumping cycle includes applying a first force to press the first bond layer and the second bond layer against each other. After the step of applying the first force, a second force lower than the first force is applied to press the first bond layer and the second bond layer against each other. After the step of applying the second force, a third force higher than the second force is applied to press the first bond layer and the second bond layer against each other.

    摘要: 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.
