摘要:
A system for fabricating an integrated circuit is disclosed that includes providing a semiconductor substrate (10), and forming a gate oxide layer (12) on an active area on the substrate. A polysilicon gate (14) is formed, on top of the gate oxide, by etching. Etch damage (16) on the substrate surface is repaired by anneal in an inert gas environment—e.g., He, Ne, N2, Ar gas, or combinations thereof.

The present invention is directed to a memory cell which comprises a storage node, a switching device for controlling access to the storage node, and a diode between the switching device and the storage node. A method for controlling charge transfer to and from a storage node through a switching device is also disclosed.

摘要:
A method for forming field isolation regions in multilayer semiconductor devices comprises the steps of masking active regions of the substrate, forming porous silicon in the exposed field isolation regions, removing the mask and oxidizing the substrate. A light ion impurity implant is used to create pores in the substrate. Substrate oxidation proceeds by rapid thermal annealing because the increased surface area of the pores and the high reactivity of unsaturated bonds on these surfaces provides for enhanced oxidation.
