A photoresist is a light-sensitive material which applied to a substrate during photolithography or photoengraving, to enable the desired pattern to be imaged. A properly exposed and developed photoresist masks portions of the substrate with extremely high precision. A positive resist is a type of photoresist in which the portion of the photoresist that is exposed to light becomes soluble to the photoresist developer. The unexposed portion of the photoresist remains insoluble to the photoresist developer. A negative photoresist is a type of photoresist in which the portion of the photoresist that is exposed to light becomes insoluble to the photoresist developer. The unexposed portion of the photoresist is dissolved by the photoresist developer. Micromarkets are defined as subsegments of the photoresist and photoresist ancillaries market included in the report. Core competencies of companies are determined in terms of their key developments and key strategies adopted by them to sustain in the market.
