A patch antenna for operation within a high temperature environment. The patent antenna typically includes an antenna radiating element, a housing and a microwave transmission medium, such as a high temperature microwave cable. The antenna radiating element typically comprises a metallization (or solid metal) element in contact with a dielectric element. The antenna radiating element can include a dielectric window comprising a flame spray coating or a solid dielectric material placed in front of the radiating element. The antenna element is typically inserted into a housing that mechanically captures the antenna and provides a ground plane for the antenna. Orifices or passages can be added to the housing to improve high temperature performance and may direct cooling air for cooling the antenna. The high temperature microwave cable is typically inserted into the housing and attached to the antenna radiator to support the communication of electromagnetic signals between the radiator element and a receiver or transmitter device.

A novel image sensor structure formed on a substrate of a first conductivity type includes a photosensitive device of a second conductivity type and a surface pinning layer of the first conductivity type. A trench isolation region is formed adjacent to the photosensitive device pinning layer. The structure includes a dopant region comprising material of the first conductivity type formed along a sidewall of the isolation region that is adapted to electrically couple the pinning layer to the substrate. The corresponding method facilitates an angled ion implantation of dopant material in the isolation region sidewall by first fabricating the photoresist layer and reducing its size by removing a corner, or a corner portion thereof, which may block the angled implant material. To facilitate the angled implant to the sidewall edge past resist block masks, two methods are proposed: 1) a spacer type etch of the imaged photoresist; or, 2) a corner sputter process of the imaged photoresist.

A wiring substrate is provided with an insulating resin film; and first and second conductive films provided on the back side and top side of the insulating resin film, respectively. The wiring substrate includes a via formed to fill a recess provided in the insulating resin film and electrically connecting the top side and back side of the insulating resin film. The via includes a first metal film formed to cover the side wall of the recess, an oxide film formed to cover the first meal film, and a second metal film formed on the metal oxide film.

A Subscriber Identity Module (SIM) card connecting device for a portable electronic device which is adapted to further reduce a thickness of the portable electronic device by limiting the height of the SIM card connecting device. The device includes: a printed circuit board (PCB); one or more patterned contacts provided on the PCB and being coupled with one or more contacts formed on the SIM card; and a housing mounted on the PCB for allowing the SIM card to be inserted into / extracted from the housing. The housing presses the inserted SIM card so that the contacts of the SIM card and the patterned contacts come into substantial pressurized contact and / or pressurized contact with each other, depending on a shape of the patterns. According to the present invention, the SIM card mounting space can be reduced, and the portable electronic device can have a further reduction in thickness.
