Method of fabricating a polymer frame with a rectangular array of cavities

摘要

An array of chip sockets defined by an organic matrix framework surrounding sockets through the organic matrix framework and a method of fabrication, the chip sockets are characterized by being rectangular with smooth walls that meet at corners that have radii of curvature of less than 100 microns thereby facilitating a close fit of each socket to the intended chip size, enabling compact chip packaging and miniaturization.
