    摘要: A method of eliminating voids in the interlayer dielectric material of 0.18-&mgr;m flash memory semiconductor devices and a semiconductor device formed by the method. The present invention provides a method for eliminating voids in the interlayer dielectric of a 0.18-&mgr;m flash memory semiconductor device by providing a first BPTEOS layer, using a very low deposition rate and having a thickness in a range of approximately 3 kÅ; and providing a second BPTEOS layer, using a standard deposition rate and having a thickness in a range of approximately 13 kÅ, wherein both layers have an atomic dopant concentration of approximately 4.5% B and approximately 5% P. This two-step deposition process completely eliminates voids in the ILD for a 0.5-&mgr;m distance (gate-to-gate) as well as 0.38-&mgr;m distance (gate-to-gate) which is the future flash technology. A low dopant/TEOS flow performed at a higher pressure during the deposition of the first layer provides an excellent gap-filling capability which eliminates voiding. Further, the present invention has the advantage of in-situ deposition of the void-free ILD0 layer of the 0.18-&mgr;m flash memory semiconductor device having a sound dopant concentration.

    摘要: Bridging between nickel silicide layers on a gate electrode and source/drain regions along silicon nitride sidewall spacers is prevented by treating the exposed surfaces of the silicon nitride sidewall spacers with a plasma containing ammonia and nitrogen to create a clean surface region having increased nitrogen. Embodiments include treating the silicon nitride sidewall spacers with an ammonia and nitrogen plasma to reduce the refractive index of the surface region to less than about 1.95.
