Abstract (en)

[origin: WO03107405A1] The invention relates to a method for producing a spacer structure. According to the inventive method, a gate insulation layer (2) comprising a gate deposition inhibition layer (2A), a gate layer (3) and a covering deposition inhibition layer (4) are formed on a semiconductor substrate (1), and the gate layer (3) and the covering deposition inhibition layer (4) are structured in such a way as to form stacks of gates (G). According to the invention, an insulation layer (6) is selectively deposited using the deposition inhibition layers (2A, 4) in order to form a spacer structure in a highly precise manner.
