  • Cascading diode switches
    Patent number: 4348651
    Abstract: An N or N.sup.+ type semiconductor substrate has a P-type layer diffused therein to form a PIN junction that is etched out between adjacent mesas and filled in with glass to form adjacent diodes between top and bottom surfaces of the substrate. The bottom surface is metallized. The top surface carries a conducting layer interconnecting the adjacent P-type portions of the mesas. This conducting layer has end portions connected to a respective diode of end width and length joined by an intermediate portion of intermediate width and length.
