    摘要: A method of fabricating a field effect transistor with increased resistance to hot carrier damage is disclosed. An oxide is grown on the gate electrode. This oxide is strengthened by nitridation and anneal. After a lightly doped drain implant, a second side oxide and a conformal nitride layer are deposited. Then, the conformal nitride is anisotropically etched to form spacers for masking a high dose drain implant. An NMOS transitor fabricated with this process has been found to be forty percent less susceptible to hot carrier damage than a conventional lightly doped drain process. Also, this process has proven to be more manufacturable than one in which the side oxide is nitrided and re-oxidized.

    摘要: A method of forming an air gap intermetal layer dielectric (ILD) to reduce capacitive coupling between electrical conductors in proximity. The method entails forming first and second electrical conductors over a substrate, wherein the electrical conductors are laterally spaced apart by a gap. Then, forming a gap bridging dielectric layer that extends over the first electrical conductor, the gap, and the second electrical conductor. In order to form a bridge from one electrical conductor to the other electrical conductor, the gap bridging dielectric materials should have poor gap filling characteristics. This can be attained by selecting and/or modifying a dielectric material to have a sufficiently high molecular weight and/or surface tension characteristic such that the material does not substantially sink into the gap. An example of such a material is a spin-on-polymer with a surfactant and/or other additives.
