LITHO-ETCH-LITHO-ETCH WITH SELF-ALIGNED BLOCKSA method for fabricating a semiconductor device includes forming a plurality of mandrel cuts from a first set of mandrels of a base structure using lithography, surrounding the first set of mandrels and a second set of mandrels of the base ...
区别在于工艺研发不同。etch意思是干法刻蚀，lithography，litho，photo都指光刻。etch只负责etch工艺研发，litho只负责litho工艺研发。工艺部门最好的是litho第二是etch。一般半导体研发中litho在前，etch在后。litho曝光完成对图案的传递后，再利用etch蚀刻技术把图案转移到光刻胶下面的film中。

曝光是将芯片图案投射到光刻胶层上,显影是使用显影液去除未曝光的光刻胶,暴露出光学图案,退光则是使用退光工艺将曝光图案转移到芯片表面。这些步骤需要高精度的设备和材料,以确保芯片的质量和精确度。 二、litho工艺在半导体研发中的应用 在半导体研发中,...

To cut lines and create vias at densities too high to achieve in one pass, several iterations of lithography and etch are used, each creating a low-density distribution of the feature. Lithography defines the location of the feature; etch removes material to form the feature and improves th...
