Abstract:
A bio-sensing semiconductor structure is provided. A transistor includes a channel region and a gate underlying the channel region. A first dielectric layer overlies the transistor. A first opening extends through the first dielectric layer to expose the channel region. A bio-sensing layer lines the first opening and covers an upper surface of the channel region. A second dielectric layer lines the first opening over the bio-sensing layer. A second opening within the first opening extends to the bio-sensing layer, through a region of the second dielectric layer overlying the channel region. A method for manufacturing the bio-sensing semiconductor structure is also provided.

Abstract:
The present disclosure relates to an integrated chip having an integrated bio-sensor with a sensing well having one or more sensing well spacers that reduce a size of the sensing well after its formation. In some embodiments, the integrated bio-sensor has a sensing device disposed within a semiconductor substrate. A dielectric structure is disposed onto a first side of the semiconductor substrate. The dielectric structure has an opening with a first width, which is exposed to an ambient environment and that overlies the sensing device. One or more sensing well spacers are arranged on sidewalls of the opening. The one or more sensing well spacers expose a bottom surface of the opening to define a sensing well having a second width that is smaller than the first width.
Abstract:
The present disclosure relates to a wafer transfer robot having a robot blade that can be used to handle substrates that are patterned on both sides without causing warpage of the substrates. In some embodiments, the wafer transfer robot has a robot blade coupled to a transfer arm that varies a position of the robot blade. The robot blade has a wafer reception area that receives a substrate. Two or more spatially distinct contact points are located at positions along a perimeter of the wafer reception area that provide support to opposing edges of the substrate. The two or more contact points are separated by a cavity in the robot blade. The cavity mitigates contact between a backside of the substrate and the robot blade, while providing support to opposing sides of the substrate to prevent warpage of the substrate.

Abstract:
The present disclosure relates to a method of gettering that provides for a high efficiency gettering process by increasing an area in which a getter layer is deposited, and an associated apparatus. In some embodiments, the method is performed by providing a substrate into a processing chamber having one or more residual gases. A cavity is formed within a top surface of the substrate. The cavity has a bottom surface and sidewalls extending from the bottom surface to the top surface. A getter layer, which absorbs the one or more residual gases, is deposited over the substrate at a position extending from the bottom surface of the cavity to a location on the sidewalls. By depositing the getter layer to extend to a location on the sidewalls of the cavity, the area of the substrate that is able to absorb the one or more residual gases is increased.
Abstract:
A method of etching a trench in a substrate is provided. The method repeatedly alternates between using a fluorine-based plasma to etch a trench, which has trench sidewalls, into a selected region of the substrate; and using a fluorocarbon plasma to deposit a liner on the trench sidewalls. The liner, when formed and subsequently etched, has an exposed sidewall surface that includes scalloped recesses. The trench, which includes the scalloped recesses, is then bombarded with a molecular beam where the molecules are directed on an axis parallel to the trench sidewalls to reduce the scalloped recesses.
