Photolithography - Meaning, Definition & English Examples
Photolithography is a process used in microfabrication to transfer geometric patterns onto a substrate, often in semiconductor manufacturing. It involves light-sensitive materials and precise exposure to create detailed designs.
Definition:
A printing process using light to transfer a pattern onto a surface, often in semiconductor manufacturing.
Synonyms:
lithography, photoprinting, photoengraving
Part of Speech:
noun
Antonyms:
freehand drawing, manual etching
Common Collocations:
semiconductor fabrication, microchip production, circuit patterning
Derivatives:
photolithographic, photolithographer
Usage Tips:
Use "photolithography" when discussing precise printing techniques in electronics or microfabrication contexts.
Common Phrases:
high-resolution photolithography, UV photolithography, maskless photolithography
Etymology:
From Greek "photo-" (light) + "lithos" (stone) + "-graphy" (writing), originally referring to stone engraving with light.
