  • Birdsbeak encroachment using combination of wet and dry etch for isolation nitride
    Patent number: 6066545
    Abstract: A technique for reducing active area encroachment (birdsbeak) by using a polysilicon hard mask combined with both wet and dry etch for the isolation nitride. This process forms a thinner layer of nitride adjacent the openings for oxide growth, which reduces stress at the silicon/nitride interface. The advantages include control over birdsbeak, reliable gate oxide quality, low junction leakage current, an improved active area, improved isolation, low peripheral junction leakage, and higher field transistor threshold voltage.
