Lithographie wafer
WebIn the manufacturing of semiconductors, structures are created on wafers by means of lithographic methods. A light sensitive film, primarily a resist layer, is coated on top of the wafer, patterned, and transfered into the … WebDirect-Write Lithography A lithography method whereby the pattern is written directly on the wafer without the use of a mask. Example: Due to throughput limitations, direct-write lithography may never be practical for IC mass production. Dispersion The variation of the index of refraction of a material as a function of wavelength.
