  • Patent number: 7457154
    Abstract: A memory system comprising a memory array having a plurality of memory units, a column decoder, a row decoder, a selecting/driving circuit and a sensing circuit is disclosed. Each memory unit comprises a gate electrode coupled to a word lines, a source region coupled to a source line or a first bit line, a drain region coupled to a drain line or a second bit line, a first spacer between the source region and the gate electrode and a second spacer between the drain region and the gate electrode. When a first-bit program operation is performed on the memory unit, a switch-on signal is applied to the gate, a programming signal is applied to the source region and the drain region is switched to ground. As the memory unit is activated, the carriers are injected and stored in a first spacer, thus represents a first bit in the memory unit.

  • Patent number: 6423646
    Abstract: The present invention discloses a method for simultaneously removing from a silicon surface polymeric films and damaged silicon layers by exposing the surface to a cleaning solution that contains amine or ethanolamine for a length of time that is sufficient to remove all such unwanted materials. The method is effective in cleaning away damaged silicon layers having a thickness between about 20 Å and about 60 Å in a period of time between about 2 minutes and about 20 minutes. In a preferred embodiment, the cleaning solution is a water solution of ethanolamine and gallic acid.

  • Patent number: 6376384
    Abstract: A method for forming a via through a silicon oxide layer. There is first provided a substrate. There is then formed over the substrate a patterned silicon nitride layer which defines a contact region beneath the patterned silicon nitride layer. There is then formed over the patterned silicon nitride layer a silicon oxide layer. There is then etched the silicon oxide layer while employing a reactive ion etch (RIE) method employing a first etchant gas composition comprising a fluorocarbon etchant gas to form: (1) an etched silicon oxide layer which exposes the contact region without substantially etching the patterned silicon nitride layer; and (2) a fluorocarbon polymer residue layer formed upon at least one of the etched silicon oxide layer and the patterned silicon nitride layer. Finally, there is stripped from the substrate the fluorocarbon polymer residue layer while employing a downstream plasma etch method employing a second etchant gas composition comprising a fluorocarbon etchant gas and oxygen.

  • Patent number: 6278189
    Abstract: A method for fabricating contact holes in high density integrated circuits and the resulting structure are disclosed. It is shown that by judiciously integrating the process of forming shallow tapered holes with self-alignment techniques, self-aligned holes can be fabricated with reduced number of masking process steps. This is accomplished by first forming shallow tapered holes to a certain depth over certain regions in a substrate by means of isotropic etching and then extending them by anisotropic etching to full depth corresponding to the regions they are allowed to contact. The net result is a whole set of holes which are self-aligned and which are formed by means of a single photoresist mask.

  • Patent number: 6265296
    Abstract: A method for making self-aligned contacts on a semiconductor substrate using a hard mask. After the transistor is formed, a blanket insulating layer is formed on said semiconductor substrate. A hard mask having openings on the blanket insulating layer is formed over the insulating layer. The openings overlay the source/drain region and part of the gate electrode structure. Using the patterned hard mask, the insulating layer is etched to the gate electrode protecting layer. Then self-aligned contacts is completed by etching the insulating layer to expose the source/drain regions using the gate electrode protecting layer and the insulating sidewall spacers as the mask.
