Abstract
A method for fabricating electric contacts for a semiconductor substrate includes depositing a first line of a first conducting material on the semiconductor substrate and depositing a second line of a second conducting material on the substrate, so as to cross the first line. The first conducting material and the second conducting material may differ from one another in that the first conducting material and the second conducting material penetrate into the substrate to different depths when subjected to a heat treatment. Furthermore, materials may differ from one another in that an electrical connection formed between the substrate and the first conducting material when subjected to the heat treatment differs in its contact resistivity from an electrical connection formed between the substrate and the second conducting material when subjected to the heat treatment. Alternatively, the method may include depositing a first line of a conducting material on the substrate, the first line including a zone of reduced thickness, and depositing a second line of a conducting material on the substrate, so as to cross the first line at the zone of the reduced thickness.
