<p>A ring quad (140) comprised of four diodes (142, 144, 146, 148). Bridges (173, 175, 177, 179) couple the anodes (183, 185, 187, 181) and cathodes (282, 284, 286, 288) of the diodes. Beam leads that are part of a lower lead (141, 143, 145, 147) package are coupled to the bottoms of the cathodes of the diodes. A method of forming a ring quad, including the steps of forming an oxide layer on top of silicon (301), forming a plurality of wells, cutting the oxide and silicon into a plurality of mesas (442, 44, 446, 448) filling channels (305, 306, 307) bordering each mesa with glass (180), forming a plurality of openings (481, 483, 485, 487), such that the metal contacts the N- layer (203, 211, 259, 253), forming a plurality of cathodes by placing metal into each of the plurality of wells such that the metal contacts the N+ layer (201, 209, 257, 251), coupling the cathodes and anodes, cutting central channels (161, 163) through a portion of glass, removing the bottom silicon, and coupling beam leads (141, 143, 145, 147) that are part of a lower lead package to the metalized bottoms (172, 174, 176, 178) of the N+ layers.</p> |
