ABSTRACT:
Multi-levels are etched into silicon. The levels are etched through a combination of crosslinking photoresist, multiple photoresist patterning and development, wet etching and/or dry-etching. RIE, DRIE, and other etch techniques can be used during different steps. The multilevel structure may thereby be produced at commercially acceptable production rates allowing the method of the present application to be used in volume production of multilevel structures.
