摘要： By growing semi-insulating CaF.sub.2 films (272) on a silicon substrate (240), forming superlattice structures (260) made of CaF.sub.2 :Nd and other semiconductor layers (294) and by associating a co-dopant with Nd in the CaF.sub.2 films photoluminescence efficiency of CaF.sub.2 films is increased. This permits using electrons to produce photons and controlling optoelectronic devices using CaF.sub.2 films through voltage variation.

摘要： Multiple trench depths within an integrated circuit device are formed by first forming trenches in a substrate to a first depth, but of varying widths. Formation of a dielectric layer can cause some of the trenches to fill or close off while leaving other, wider trenches open. Removal of a portion of the dielectric material can then be tailored to expose a bottom of the open trenches while leaving remaining trenches filled. Removal of exposed portions of the underlying substrate can then be used to selectively deepen the open trenches, which can subsequently be filled. Such methods can be used to form trenches of varying depths without the need for subsequent masking.

摘要： According to the present invention, an ultrathin buried diffusion barrier layer (UBDBL) is formed over all or part of the doped polysilicon layer of a polysilicide structure composed of the polycrystalline silicon film and an overlying film of a metal, metal silicide, or metal nitride. More specifically, according to one embodiment of the present invention, a memory cell is provided comprising a semiconductor substrate, a P well, an N well, an N type active region, a P type active region, an isolation region, a polysilicide gate electrode structure, and a diffusion barrier layer. The P well is formed in the semiconductor substrate. The N well is formed in the semiconductor substrate adjacent to the P well. The N type active region is defined in the P well and the P type active region is defined in the N well. The isolation region is arranged to isolate the N type active region from the P type active region. The polysilicide gate electrode structure is composed of a polycrystalline silicon film and an overlying metal, metal silicide, or metal nitride film. The polycrystalline silicon film comprises an N+ polysilicon layer formed with the N type active region and a P+ polysilicon layer formed with the P type active region. The diffusion barrier layer is formed in the polysilicide gate electrode structure over a substantial portion of the polycrystalline silicon film between the polycrystalline silicon film and the metal, metal silicide, or metal nitride film.
