    • In a CVD vacuum chamber processing system for depositing a blanket of refractory material, such as tungsten, upon a frontside of a semiconductor wafer, an inert gas, such as argon is directed to the backside of the wafer in a manner so as to prevent the chamber reaction gases from reacting with polysilicon or other materials on the backside of the wafer as well as to prevent the deposition of the blanket material on the backside of the wafer. This method alleviates the problems of particulate generation and loss of wafer backside datum surface due to the inadvertent buildup of unwanted materials. The wafer is placed on a heater platen and is secured by a specified range of vacuum pressures. The wafer is exposed to specified ranges of chamber pressure during the deposition phase. During the purge phase, the chamber pressure is reduced and the wafer chucking pressure is increased to a specified range. The method is terminated with the equalization of pressure between the front and backside of the wafer.
    • 在CVD真空室处理系统中,用于在半导体晶片的前侧沉积耐火材料(例如钨)的毯子,惰性气体例如氩气以这样的方式被引导到晶片的背面,以防止 室反应气体与晶片背面的多晶硅或其他材料反应,以及防止覆盖材料沉积在晶片的背面。 该方法由于无意的材料的无意积累而减轻了颗粒产生和晶片背面基准表面损失的问题。 将晶片放置在加热器台板上并通过特定范围的真空压力固定。 在沉积阶段,晶片暴露于规定范围的室压力。 在清洗阶段期间,腔室压力降低,并且晶片夹紧压力增加到指定范围。 该方法通过晶片的前侧和后侧之间的压力均衡来终止。
