摘要: A method for fabricating a drain/source path is provided, in which essentially firstly a nitride layer is applied, on which a TEOS layer is then patterned. The patterning is effected in a simplified manner by virtue of the fact that the nitride layer acts as an etching stop layer during the etching away of the TEOS layer.
