Abstract (en)

[origin: DE10149773A1] Process for selecting faulty dielectrics (2) of semiconductor component (1) comprises: forming a testing layer (3) during production of the component above dielectrics; simultaneously testing functionality of the dielectrics by applying electrical voltage on testing layer above and on substrate (4) below dielectrics; and removing or structuring testing layer to continue to production of component. Preferred Features: The testing layer is produced by intermediate structuring of the material layers already produced by the production process. The testing layer is made from polysilicon or polysilicon-germanium.
