Abstract: The present invention provides a fluid dispensing system and method wherein, after dispensing a fluid, a scavenging pump is used to remove (i.e., scavenge) residual fluid from the dispensing hose without encountering the drawbacks of the prior art. Another advantage is that the scavenging pump can be utilized for priming a main fluid supply used to supply fuel to the dispensing hose.

Abstract: A method of forming an implanted pocket region, to reduce short channel effects (SCE), for narrow channel length, NMOS devices, has been developed. After forming an initial indium pocket region, with an initial indium profile, in the area of a P type semiconductor to be used to accommodate an N type source/drain region, a low temperature anneal procedure is used to activate indium ions in the initial indium pocket region, and to create a final indium pocket region, featuring a final indium profile. The final indium profile remains unchanged after experiencing subsequent high temperature procedures, such as a post-heavily doped, source/drain anneal. The narrow channel length NMOS devices, fabricated using the low temperature anneal procedure described in this invention, resulted in a reduced Vt roll-off phenomena, when compared to counterpart, narrow channel length NMOS, formed without the benefit of the low temperature anneal procedure.

Abstract: An apparatus and a method for oxidizing silicon substrates by either a wet oxidation or a dry oxidation process in the same oxidation chamber are provided. In the apparatus, an additional conduit is provided for evacuating any residual water vapor trapped in a conduit section between an external torch and the oxidation chamber such that residual water vapor does not flow into the oxidation chamber and cause problems for a dry oxidation process subsequently conducted. The present invention novel apparatus therefore allows thin silicon oxide films such as those used in gate oxides to be formed with high quality in the same oxidation chamber. The present invention novel apparatus further allows high quality tri-layered silicon oxide films to be formed in a dry-wet-dry oxidation process for achieving satisfactory deposition rates and high quality oxide films on the substrate.
