摘要:
A method of manufacturing a device comprises depositing one or more metallization layers to a substrate, locally heating an area of the one or more metallization layers to obtain a substrate/metallization-layer compound or a metallization-layer compound, the compound comprising an etch-selectivity toward an etching medium which is different to that of the one or more metallization layers outside the area, and removing the one or more metallization layers in the area or outside the area, depending on the etching selectivity in the area or outside the area, by etching with the etching medium to form the device.
摘要(中):
一种制造器件的方法包括将一个或多个金属化层沉积到衬底上,局部加热所述一个或多个金属化层的区域以获得衬底/金属化层化合物或金属化层化合物,所述化合物包含蚀刻 - 选择性不同于区域外的一个或多个金属化层的蚀刻介质的选择性,以及根据该区域或区域外的蚀刻选择性,去除该区域或区域外的一个或多个金属化层, 通过用蚀刻介质蚀刻以形成该器件。
