Abstract: Implementations described herein generally relate to substrate processing equipment and more particularly to methods and compositions for temperature control of substrate processing equipment. In one implementation, a method of cooling a processing chamber component is provided. The method comprises introducing an inert purge gas into a supply reservoir containing a coolant and flowing the treated coolant to a processing chamber component to cool the processing chamber component. The coolant initially comprises deionized water and a water-soluble base.

Abstract: A method and apparatus for thermally processing a substrate is provided. A substrate is disposed within a processing chamber configured for thermal processing by directing electromagnetic energy toward a surface of the substrate. An energy blocker is provided to block at least a portion of the energy directed toward the substrate. The blocker prevents damage to the substrate from thermal stresses as the incident energy approaches an edge of the substrate.

Abstract: Embodiments of the invention generally provide a method for forming a doped silicon-containing material on a substrate. In one embodiment, the method provides depositing a polycrystalline layer on a dielectric layer and implanting the polycrystalline layer with a dopant to form a doped polycrystalline layer having a dopant concentration within a range from about 1×1019 atoms/cm3 to about 1×1021 atoms/cm3, wherein the doped polycrystalline layer contains silicon or may contain germanium, carbon, or boron. The substrate may be heated to a temperature of about 800° C. or higher, such as about 1,000° C., during the rapid thermal anneal. Subsequently, the doped polycrystalline layer may be exposed to a laser anneal and heated to a temperature of about 1,000° C. or greater, such within a range from about 1,050° C. to about 1,400° C., for about 500 milliseconds or less, such as about 100 milliseconds or less.

Abstract: In one embodiment, the invention generally provides a method for annealing a doped layer on a substrate including depositing a polycrystalline layer to a gate oxide layer and implanting the polycrystalline layer with a dopant to form a doped polycrystalline layer. The method further includes exposing the doped polycrystalline layer to a rapid thermal anneal to readily distribute the dopant throughout the polycrystalline layer. Subsequently, the method includes exposing the doped polycrystalline layer to a laser anneal to activate the dopant in an upper portion of the polycrystalline layer.

Abstract: The present invention relates to a low-pressure chemical vapor deposition (LPCVD) process for depositing silicon dioxide. In particular, the present invention describes a process involving a pre-cleaning step in which all impurities are removed from the substrate followed by a LPCVD step performed at temperatures of between 200.degree. C. and 300.degree. C. The process of the present invention is intended to replace higher temperature LPCVD and thermal processes for depositing silicon dioxide.More particularly, the present invention involves a process in which a substrate is washed using a predetermined cleaning process. The substrate is then exposed to a dilute hydrofluoric acid solution which removes native oxide and contaminants from the surface. Next, the substrate is rinsed with, for example, de-ionized water or ultra-clean water to remove any hydrofluoric acid or other residue from the previous process steps.

Abstract: A process for setting the exposure speed of photolithography instruments is described, using a method of dosimetry based on photoactive compound bleaching of photoresist. A curve of light absorbance to exposure speed and a calibration curve of light absorbance to dose are determined for a photoresist. The exposure speed for any desired degree of resist bleaching can be set using the first curve, and the exposure speed for a predetermined dosage can be set by determining the common light absorbance value on the exposure speed and dosage curves.
