ABSTRACT:
Superposed fine-detail multi-level patterns (e.g., superposed diffraction gratings having specified line spacing dimensions less than 10 micrometers and specified depth dimensions less than 5 micrometers) can be fabricated by linearly adding (e.g., by evaporation) an additional two-level pattern to an existent multi-level pattern or, alternatively, by linearly subtracting (e.g., by sputter or plasma etching) an additional two-level pattern to an existent multi-level pattern.
