Abstract:
An improved method for providing electrical connection to a photodetector in a Dewar flask is disclosed. A plurality of conductive paths are formed on the inner flask of the Dewar. Each of the conductive paths extends from the side surface on to the top surface of the inner flask. A photodetector having lead tabs is mounted to the top surface of the inner flask with the lead tabs aligned with the conductive paths. The lead tabs are bonded to the conductive paths to provide electrical connection to the photodetector.
Abstract:
Techniques for minimizing stress induced by temperature changes in an integrated circuit (e.g., focal plane array or processor) or other such assemblies that include materials having mismatched coefficients of thermal expansion/contraction are disclosed. A thermal interface including a flexible comb-like pattern enables compensation for mismatched coefficients thereby reducing thermal-related stress.
Abstract:
An improved method for providing electrical conductive paths in a Dewar flask is disclosed. A thin metal film is deposited over the side and top of the inner flask of the Dewar. Portions of the metal film are then selectively removed to provide electrical conductive paths which extend from the side on to the top of the inner flask.
Abstract:
An electromagnetic radiation detector has a first surface which receives incident electromagnetic radiation. The sides of the detector are sloped such that incident radiation does not initially strike the sides.
Abstract:
An improved method for fabricating lead throughs in a Dewar flask is disclosed. Each lead through is provided with a contact portion which is essentially parallel to the side surface of the inner flask. The contact portion is bonded to a conductive path on the side surface of the inner flask.
