摘要： A transmission electron microscopy (TEM) or scanning electron microscopy (SEM) sample preparation method includes the steps of depositing a metal layer on top of a substrate, depositing a silicon nitride passivation layer on top of the metal layer, and cutting the substrate and the metal and passivation layers to expose their cross-sections for examination by electron microscopy. As a result, a TEM/SEM sample having sharp, well-defined boundaries is produced.

摘要： Photoresist masks are stripped using a H.sub.2 -N.sub.2 plasma to prevent increasing the dielectric constant of an exposed carbon-containing dielectric material. Embodiments of the present invention include forming a low dielectric constant, carbon-containing layer, e.g., a polymeric layer, on an exposed metal feature overlying a wafer, forming a photoresist mask on the dielectric layer, forming an opening in the dielectric layer exposing the metal feature and a portion of the dielectric layer, preheating the wafer and stripping the photoresist mask using the H.sub.2 -N.sub.2 plasma.

摘要： This invention describes improved apparatus and methods for spin-on deposition of semiconductor thin films. The improved apparatus provides for controlled temperature, pressure and gas compositions within the deposition chamber.

In one embodiment, the precursor solution is dispensed from the outer edge of the wafer toward the center. In alternative embodiments, processors regulate the movement of the dispensing arm and the precursor pump to provide an evenly dispensed layer of precursor solution. The invention also describes improved methods for evaporating solvents and curing thin films. The methods of this invention enable the production of spin-on thin films, which have more even film thickness and uniformity. The semiconductor thin films produced by the methods of this invention are useful for the manufacture of semiconductor devices comprising interlevel dielectric materials.

摘要： The present invention is a method and system for eliminating voids in a semiconductor device. The method comprises the steps of forming metal lines over a semiconductor substrate, forming a first oxide layer utilizing a high density plasma deposition technique, forming a second oxide layer utilizing a carbon free resin and forming a topside dielectric layer. Through the use of a method in accordance with the present invention, the voids that are created in the dielectric films during conventional semiconductor processing methodology are eliminated. The use of a high density plasma deposition technique provides a more directional deposition that can get between metal lines that are separated by smaller gaps. The dielectric films are thereby strengthened, which increases the reliability of the semiconductor device. Furthermore, by utilizing hydrogen silsesquiloxane instead of a conventional spin-on glass, there is no concern regarding carbon contamination since hydrogen silsesquiloxane doesn't contain carbon atoms.
