    • A processing system, a processing method, and a storage medium storing computer program are provided to automatically and accurately maintain uniformity of a film thickness of a film formed on a semiconductor wafer by adjusting a flow rate of the gas supplied to the wafer. A wafer(W) to be treated is received in a process chamber(2). Process gas supply members(16-20) supply process gas into the process chamber. A process condition memory stores process conditions including a mass flow rate of the process gas supplied from the process gas supply members. A model memory stores a flow rate-result relation model, which represents a relation between a mass flow of the process gas and a process result. A mass flow calculator(50) receives the process result at the process condition stored in the process condition memory, and calculates the mass flow of the process gas based on the process result and the flow rate-result relation stored in the model memory. Process members(21-25) change the mass flow of the process gas to the calculated flow rate of the mass flow calculator, and processes the water by using the calculated flow rate.

    • A semiconductor substrate having a silicon layer (24,26,28) is provided. In one embodiment, the substrate is a silicon-on-insulator (SOI) substrate (12,14,24,26,28) having an oxide layer (14) underlying the silicon layer (24,26,28). An amorphous or polycrystalline silicon germanium layer (32) is formed overlying the silicon layer (24,26,28). Alternatively, germanium is implanted into a top portion of the silicon layer (24,26,28) to form an amorphous silicon germanium layer (32). The silicon germanium layer (32) is then oxidized to convert the silicon germanium layer into a silicon dioxide layer (34) and to convert at least a portion of the silicon layer (24,26,28) into germanium-rich silicon (36,38). The silicon dioxide layer (34) is then removed prior to forming transistors (48,50,52) using the germanium-rich silicon (36,38). In one embodiment, the germanium-rich silicon (36,38) is selectively formed using a patterned masking layer (30) over the silicon layer (28) and under the silicon germanium layer (32). Alternatively, isolation regions may be used to define local regions of the substrate in which the germanium-rich silicon is formed. ® KIPO & WIPO 2007
    • 提供具有硅层(24,26,28)的半导体衬底。 在一个实施例中,衬底是在硅层(24,26,28)下方具有氧化物层(14)的绝缘体上硅(SOI)衬底(12,14,24,26,28)。 在硅层(24,26,28)上形成非晶或多晶硅锗层(32)。 或者,将锗注入硅层(24,26,28)的顶部以形成非晶硅锗层(32)。 硅锗层(32)然后被氧化以将硅锗层转化成二氧化硅层(34)并将至少一部分硅层(24,26,28)转化为富含锗的硅(36, 38)。 然后在使用富锗的硅(36,38)形成晶体管(48,50,52)之前去除二氧化硅层(34)。 在一个实施例中,富锗富硅(36,38)使用硅层(28)上方的图案化掩模层(30)和硅锗层(32)下选择性地形成。 或者,可以使用隔离区来限定其中形成富锗的硅的衬底的局部区域。 ®KIPO&WIPO 2007
