    • The present invention provides a method for forming a silicon nitride spacer by using an atomic layer deposition (ALD) method. The procedure of the ALD is to use a first kind of excess gas as a reactant air and thus produce a first mono-layer solid phase of the first reactant air on the wafer. When the first chemical reaction is completed, the first excess air is drawn out, and then the second excess air is released to deposit a second mono-layer solid phase of the second reactant air on the first mono-layer solid phase. In this way, a whole deposited layer with a layer of the first mono-layer solid phase, a layer of the second mono-layer solid phase, and so on are stepwise formed on the wafer surface. The ALD method is a time consuming task in deposition process such as in the generation of 0.35 &mgr;m to 0.5 &mgr;m of VLSI ages. However, in the generation of 0.18 &mgr;m, 0.13 &mgr;m or beyond of VLSI ages, because the device is getting smaller than ever before, the deposition speed of the ALD method is just right on time to meet the demand and is an appropriate method in depositing silicon nitride spacer.
    • 本发明提供了通过使用原子层沉积(ALD)方法形成氮化硅间隔物的方法。 ALD的过程是使用第一种过量气体作为反应物空气,从而在晶片上产生第一反应物空气的第一单层固相。 当第一化学反应完成时,第一过量空气被抽出,然后第二过量空气被释放,以将第二反应物空气的第二单层固相沉积在第一单层固相上。 以这种方式,在晶片表面上逐步形成具有第一单层固相层,第二单层固相层等的全部沉积层。 ALD方法在沉积过程中是耗时的任务,例如在0.35m至0.5mil的VLSI年龄的产生中。 但是,由于器件比以往任何时候都要小,所以在0.18微米,0.13微米或超过VLSI的时代,ALD方法的沉积速度正好准时满足需求,是一种适当的方法 氮化硅间隔物。

    • An off axis illumination stepper exposure system includes an illumination system with an aperture element and lenses. The aperture element comprises an array of electronically switchable pixels in a matrix. The aperture element can be a transmissive spatial light modulator. An annular pattern of transmissivity through an aperture element is provided by a spatial light modulator operated under computer control. The computer can select and provide variable dimensions of the pattern to optimize operation of the device. In addition to a first transmissive spatial light modulator providing an aperture in the illumination system with a pattern of transmissivity operated under computer control, a mask is provided in the form of a second transmissive spatial light modulator operated under computer control operating cooperatively to provide images projected through a projection system onto a workpiece supported upon a stepper tool.
