Abstract
A housing arrangement for a plurality of semiconductor chips (1) is disclosed, in which each of the chips is received in a respective frame or cassette (4), there being a first electrically conductive member (5), having portions (6) which are in electrical connection with one face of each of the chips and a second electrically conductive member (7), having portions (8) which are in electrical connection with an opposite face of each of the chips.
Claims5
A housing arrangement for a plurality of semiconductor chips, in which each of said chips is received in a respective frame to form a discrete sub-assembly, there being a first electrically conductive member, having portions which are in electrical connection with one face of each of the chips, and a second electrically conductive member, having portions which are in electrical connection with an opposite face of each of the chips, a local axis of each of said chips and its respective connecting portions being free to move by thermal expansion relative to such a local axis of any other of said chips and its connecting portions, substantially without transferring stress between any of said chips, and wherein the frames are shaped so that, for each two adjacent frames, a projection on one side wall face of one of them enters into a recess of a side wall face of the other.
A housing arrangement for a plurality of semiconductor chips, in which each of said chips is received in a respective frame to form a discrete sub-assembly, there being a first electrically conductive member, having portions which are in electrical connection with one face of each of the chips, and a second electrically conductive member, having portions which are in electrical connection with an opposite face of each of the chips, wherein each frame engages a clip, the clip acting to retain components within its associated frame, and portions of each clip engage with protrusions formed on side wall faces of its associated frame, and wherein the frames and clips are shaped so that, for each two adjacent frames, a protrusion and engaging clip portion on one side wall face of one frame enters into a recess of a side wall face of the other frame.
