1,002,725. Semi-conductor devices. CLEVITE CORPORATION. Jan. 3, 1963 [Feb. 6, 1962], No. 361/63. Heading H1K. A semi-conductive element is provided with a lead wire formed of a core of relatively hard metal with an adherent coating of a relatively soft metal, attached to the element by thermocompression bonding. In the embodiment (Fig. 2) a semi-conductor element of silicon 22 is gold-alloyed to a header member (Fig. 1, not shown), and has a base region 24 formed in its surface by diffusion of boron into the element, and an emitter region 26 formed by diffusion of phosphorus. The diffusion areas may be defined by a SiO 2 mask pattern 29. Two aluminium strips 28 and 30 are provided on the element to which electrode connection is made by a molybdenum wire 10 having a gold coating 11 by a thermo-compression bonding technique. A portion of exposed molybdenum core 34 is subjected to a hydrogen peroxide etch to separate the electrode connections. The wire core may be nickel or tungsten with a silver coating.

The present invention provides an image sensor module, including an integrated circuit substrate, an image sensing chip, a cover plate and an encapsulating material. The image sensing chip is disposed on the integrated circuit substrate. The image sensing chip includes an image sensing area and a non-image sensing area. A dam is disposed between the cover plate and the non-image sensing area of the image sensing chip. The cover plate includes a transparent material and a cushioning material. The encapsulating material covers the periphery of the image sensing chip, the periphery of the dam, part of the integrated circuit substrate and the periphery of the cover plate. The cushioning material is disposed between the transparent material and the dam and between the transparent material and the encapsulating material. The present invention reduces the possibility that the encapsulating material will peel off the cover plate.

A electronic device including lead attachment structure which permits operation of the devices over a wide temperature range. The device comprises a core conductor having a thin coating of metal thereon whereby only a limited amount of coating material is available to form an alloy which bonds the core conductor to the device electrode, the electrode composition thus being affected only in the region adjacent the lead and the bond between the electrode and device being unaffected.
