Mask shop


A mask shop is a factory which manufactures photomasks for use in the semiconductor industry. There are two distinct types found in the trade. Captive mask shops are in-house operations owned by the biggest semiconductor corporations, while merchant mask shops make masks for most of the industry.
Merchant mask shops will produce photomasks for a variety of integrated device manufacturers, foundries or optical device companies in addition to providing excess cavity work and re-pellicle for captive mask shops.
The company structure is similar to that of any medium-sized manufacture and has the
following unique departments or mask makers:
  • Sales Customer / customer services
  • Front end data prep
  • Facilities maintenance - plant & environment
  • Engineering - equipment maintenance
  • Engineering - process, inspection & metrology
  • Quality assurance
  • Shipping & dispatching

Photomask market

The worldwide photomask production market was $3.1 billion in 2013. Almost half of market attributed to captive mask shops.

Infrastructure (technical and financial)

The costs of creating new mask shop for 180 nm processes were estimated in 2005 as $40 million, and for 130 nm - more than $100 million. In 2013 cost of new 28 nm mask shop was estimated at $110 – 140 million.

Future

As technology shrinks, the cost to mask shops increase and the product turn around time grow longer as well.
