Abstract:
An electronic device and methods of manufacture thereof. One or more methods may include providing a lid wafer having a cavity and a surface surrounding the cavity and a device wafer having a detector device and a reference device. In certain examples, a solder barrier layer of titanium material may be deposited onto the surface of the lid wafer. The solder barrier layer of titanium material may further be activated to function as a getter. In various examples, the lid wafer and the device wafer may be bonded together using solder, and the solder barrier layer of titanium material may prevent the solder from contacting the surface of the lid wafer.

Abstract:
Methods for reducing wafer bow induced by an anti-reflective coating of a cap wafer are provided. The method may utilize a shadow mask having at least one opening therein that is positioned opposite recessed regions in a cap wafer. The method may further include depositing at least one layer of an anti-reflective coating material through the shadow mask onto a planar side of a cap wafer to provide a discontinuous coating on the planar side.
Abstract:
In certain embodiments, a system includes a deposition system and a plasma/bonding system. The deposition system deposits a solder outwardly from a substrate of a number of substrates. The plasma/bonding system comprises a plasma system configured to plasma clean the substrate and a bonding system configured to bond the substrates. The plasma/bonding system at least reduces reoxidation of the solder. In certain embodiments, a method comprises depositing solder outwardly from a substrate, removing metal oxide from the substrate, and depositing a capping layer outwardly from the substrate to at least reduce reoxidation of the solder.

Abstract:
A structure for detecting electromagnetic radiation having a predetermined wavelength. The structure includes a device wafer having a sensing element disposed on a predetermined region of a surface of the device wafer responsive to the electromagnetic radiation. A cover wafer is provided having a region thereof transparent to the electromagnetic radiation for passing the electromagnetic radiation through the transparent region onto a surface of the sensing element. A bond gap spacer structure is provided for supporting the surface of the sensing element from an opposing surface of the transparent region of the cover wafer a distance less than a fraction of the predetermined wavelength when. the cover wafer is bonded to the device wafer.
