Examples

  • Each new lithographic wavelength has required the development of new photoresists specifically tailored to it.

    Academic text (2001)
  • Instead, ultraviolet light is projected through masks to expose wafers coated with photoresist.

    Academic text (1997)
  • Here, the pattern is first defined by photoresist.

    Academic text (1998)
  • The surfaces of the metal part are finished, and the photoresist is dissolved, leaving the finished parts.

    Academic text (2005)
  • The last step is to dissolve the photoresist from under the metal.

  • Copper is electrochemically plated, and then the photoresist and seed layer are removed.

    Academic text (1995)
  • Then, a 20-microm-thick photoresist is coated and patterned, which in turn is used as a plating stencil.

    Academic text (1995)
  • Electrochemical processing through polymeric photoresist masks is a primary technique for microfabrication of high-density patterned structures.

    Academic text (1998)
  • To fabricate each of these curved mirrors, researchers formed a photoresist disk on a planar GaAs–GaAs optical cavity.

is specialized for creating fine patterns on surfaces in electronics photolithography

Surface Forms

photoresist singular
photoresists plural

Morphology

photoresist = resist (semi-transparent) = photo + resist

The parts suggest a light-related resist, but the specialized electronics meaning is not fully predictable for an average learner.

Etymology

Photoresist combines photo- meaning 'light' (as in photograph) and resist meaning 'to refuse or stop', so it is a material that works with light to control which parts stay or are removed. That's why a photoresist is a light-sensitive coating used to make tiny patterns on chips and other surfaces.
