摘要： An integrated circuit having semiconductor devices is connected by a first conductive channel damascened into a first oxide layer above the devices. A stop nitride layer, a via oxide layer, a via nitride layer, and a via resist are sequentially deposited on the first channel and the first oxide layer. The via resist is photolithographically developed with rectangular cross-section vias greater than the width of the channels and the via nitride layer is etched to the rectangular cross-section. A second channel oxide layer and a second channel resist are sequentially deposited on the via nitride layer and the exposed via oxide layer. The second channel resist is photolithographically developed with the second channels and an anisotropic oxide etch etches the second channels and rectangular box vias down to the stop nitride layer. He stop nitride layer is nitride etched in the rectangular via configuration and conductive material is damascened into the second channels and the via to be chemical-mechanical polished to form the interconnections between two levels of channels.

摘要： A method for shrinking a semiconductor device and minimizing auto-doping problem is disclosed. An etch stop layer is eliminated and is replaced with a consumable liner oxide layer so that stacked gate structures of the device can be positioned closer together, thus permitting shrinking of the device. The liner oxide layer is formed directly over a substrate and in contact with stacked gate structures, sidewall spacers, and sources and drains formed on the substrate, and serves as an auto-doping barrier for the dielectric layer to prevent boron and phosphorous formed in the dielectric layer from auto-doping into the sources and drains.

摘要： The present invention provides systems and methods that facilitate formation of semiconductor devices via planarization processes. The present invention utilizes dishing effects that typically occur during a chemical mechanical planarization (CMP) process. A reducing CMP process is performed on a semiconductor device in order to form a passive layer instead of performing a first CMP, followed by a deposition and a second CMP to form a passive layer. The reducing CMP process utilizes a slurry that includes a reducing chemistry that forms the passive layer in a dish region of an electrode. Thus, the passive layer is formed in conjunction with the reducing CMP process utilized for forming the electrode.
