摘要:
A method of removing at least a portion of a layer of material from over a semiconductor substrate that can include dispensing an etching solution over the semiconductor substrate to form a pool of etching solution on the layer of material, wherein a footprint of the pool of etching solution is less than a footprint of the semiconductor substrate. The pool of etching solution and the semiconductor substrate can be moved with respect to each other. A pool boundary of the pool of etching solution can be defined on the semiconductor substrate with at least one air-knife such that the pool of etching solution etches the layer of material over the semiconductor substrate within the footprint of the pool of etching solution. The etching solution and at least a portion of the layer of material etched by the etching solution can be removed with the at least one air-knife.
摘要(中):
一种从半导体衬底上去除材料层的至少一部分的方法,其可以包括在半导体衬底上分配蚀刻溶液以在该材料层上形成蚀刻溶液池,其中蚀刻池的覆盖区 溶液小于半导体衬底的覆盖区。 蚀刻溶液池和半导体衬底可以相对于彼此移动。 可以使用至少一个气刀在半导体衬底上限定蚀刻溶液池的池边界,使得蚀刻溶液池在蚀刻溶液池的覆盖区内蚀刻半导体衬底上的材料层。 蚀刻溶液和由蚀刻溶液蚀刻的材料层的至少一部分可以用至少一个气刀去除。
