  • Technique to radiation-harden trench refill oxides
    Patent number: 8021991
    Abstract: Oxide films are deposited under conditions generating a silicon-rich oxide in which silicon nanoclusters form either during deposition or during subsequent annealing. Such deposition conditions include those producing films with optical indices (n) greater than 1.46. The method of the present invention reduces the TID radiation-induced shifts for the oxides.
