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.
Claims6
A semiconductor device package comprising:
- a unitary semiconductor package element including a base and side walls projecting transversely to said base for containing a semiconductor chip within said side walls;
- a generally planar lid having opposed first and second surfaces and a periphery, a part of said first surface being bonded to said side walls of said semiconductor package element;
- and
- a cooler bonded to said second surface of said lid wherein the part of said first surface of said lid bonded to said side walls of said semiconductor package element is positioned inside and spaced from the periphery of said lid by a predetermined distance.
