ABSTRACT:
A semiconductor integrated circuit device includes a rigid planar member or cover affixed to and overlying at least a portion of the upper surface of a semiconductor integrated circuit bar. The upper surface of the planar member is textured to lock the member to the encapsulating medium, and has a thermal coefficient of expansion similar to that of the integrated circuit bar. According to another aspect of the invention the planar member is formed of a material having a low alpha particle emission.
