Abstract:
A micro-structure is manufactured by patterning a sacrificial film, forming an inorganic material film on the pattern, providing the inorganic material film with an aperture, and etching away the sacrificial film pattern through the aperture to define a space having the contour of the pattern. The patterning stage includes the steps of (A) forming a sacrificial film using a composition comprising a cresol novolac resin and a crosslinker, (B) exposing patternwise the film to first high-energy radiation, (C) developing, and (D) exposing the sacrificial film pattern to second high-energy radiation and heat treating for thereby forming crosslinks within the cresol novolac resin.
