Abstract: A semiconductor device package includes a semiconductor package element for containing a semiconductor chip, a lid bonded to the semiconductor package using an adhesive agent, and a cooler bonded to a surface of the lid. The bonded surface between the semiconductor package and the lid is positioned inside the periphery of the lid by a predetermined distance. Thus, the adhesive agent does not adhere to a side nor surface of the lid and a cooler can be easily bonded to the lid surface. As a result, a highly reliable semiconductor device is provided and easily aligned at the time of forming a module by using a plurality of packages.

Abstract: A one-dimensional time-delay integration solid-state imager includes a plurality of light-to-electricity conversion parts which store signal charges generated in response to incident light, a vertical CCD corresponding to a series of the light-to-electricity conversion parts for transferring stored signal charges, and a gate for controlling transfer of signal charges stored at the light-to-electricity conversion parts to the vertical CCD. The signal charges corresponding to the same observed image moving on the plurality of light-to-electricity conversion parts are added to enhance the signal-to-noise ratio, and a background signal charge removing region for removing background signal charges is provided at the vertical CCD for removing background charges during the transfer of signal charges.
