  • Structure and fabrication of SiCr microfuses
    Patent number: 5340775
    Abstract: A SiCr microfuse, deletable either by electrical voltage pulses or by laser pulses, for rerouting the various components in an integrated circuit, as where redundancy in array structures is implemented, and the method of fabricating same, at any wiring level of the chip, by utilizing a direct resist masking of the SiCr fuse layer to eliminate problems of mask damage and residual metal adjacent the fuse.
    Type: Grant

  • Keying system for assuring proper array configuration of cable cards
    Patent number: 4900274
    Abstract: A keying system for assuring the proper sequence or arrangement of cable cards within a card grouper is provided. The grouper includes a plurality of slots to receive the cable cards. The cards include tab means at at least one side thereof which can be selectively trimmed to one of several specific extension distances from the card. The grouper includes a template which has grooves configured to receive cards having their tabs programmed to one and only one configuration. Thus any given card, when programmed, will fit in only one location. The cards and grouper also include coacting surfaces to allow the appropriate card to be inserted in only one orientation in any given slot.
