    • A method of forming a semiconductor device, includes forming a layer of oxide on a semiconductor substrate, forming a layer of silicon nitride on the oxide layer, forming isolation regions in the substrate using the oxide layer and the nitride layer, removing the silicon nitride layer, ion implanting dopant ions using the original oxide layer as a screen, into the substrate, and removing the oxide layer and forming a gate oxide layer over the substrate. Another method of forming an active area of a semiconductor device, includes using a pad oxide, remaining after removing a film layer thereover of an oxide/film mask stack, for a screen layer for well implants formed in the substrate, removing the oxide layer and forming a gate oxide over the substrate, following defining the well implants, without using a sacrificial oxide.
    • 一种形成半导体器件的方法,包括在半导体衬底上形成氧化物层,在氧化物层上形成氮化硅层,使用氧化物层和氮化物层在衬底中形成隔离区域,去除氮化硅层 ,使用原始氧化物层作为屏幕的离子注入掺杂剂离子进入衬底,并且去除氧化物层并在衬底上形成栅极氧化物层。 形成半导体器件的有源区域的另一种方法包括使用衬垫氧化物,在除去氧化物/膜掩模叠层之上的膜层之后留下用于在衬底中形成的阱注入的屏蔽层,去除氧化物层和 在不使用牺牲氧化物的情况下,在定义井注入之后,在衬底上形成栅极氧化物。

    • A phase-shifting photomask with a self aligned undercut rim-shifting element and methods for its manufacture are provided. One embodiment of the invention provides a method of manufacturing a phase-shifting photomask having a self aligned rim-shifting element, the method comprising: applying a patterning film to a first portion of a transparent substrate; etching the substrate to a depth to remove a second portion of the substrate not beneath the patterning film; etching the first portion of the substrate to undercut an area beneath the patterning film; and removing the patterning film, wherein the etched substrate forms a self-aligned undercut rim-shifting element.
    • 提供了具有自对准底切边缘移动元件的相移光掩模及其制造方法。 本发明的一个实施例提供了一种制造具有自对准边缘移位元件的相移光掩模的方法,所述方法包括:将图案化膜施加到透明基板的第一部分; 将衬底蚀刻到深度以去除衬底的第二部分而不在图案化膜下方; 蚀刻基板的第一部分以削去图案化膜下方的区域; 并且去除所述图案化膜,其中所述蚀刻的衬底形成自对准底切轮辋移位元件。
