  • Patent number: 5561319
    Abstract: A CMOS integrated circuit structure is disclosed having a patterned nitride passivation layer, wherein the nitride is patterned such that it does not overlie the thin gate oxide portions of one or more of the MOS devices. When protection against the effects of external radiation is desired, the thin gate oxide areas of the PMOS devices are left uncovered by the patterned nitride passivation layer. When protection is desired against the effects of internally generated "hot electrons", the thin gate oxide areas of the NMOS devices are left uncovered by the patterned nitride passivation layer.

  • Patent number: 5516731
    Abstract: A technique for improving the radiation hardness and hot-electron resistance of a CMOS integrated circuit is described whereby undesirable hydrogen ions may be vented through any holes, such as contact holes, in an overlying passivation layer by applying an elevated temperature and/or electrical bias to the integrated circuit die. The elevated temperature and electrical bias serve to accelerate the process by which hydrogen vents from the die. The elimination of unwanted hydrogen significantly reduces threshold shifts in the CMOS integrated circuit, providing greater radiation hardness and hot-electron resistance.
