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. [26] The purchase price of a photomask, in 2006, could range from $250 to $100,000 [27] for a single high-end phase-shift mask. As many as 30 masks (of varying price) may be required to form a complete mask set.
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. [2] In 2013 cost of new 28 nm mask shop was estimated at $110 – 140 million. [3]
Mask work exclusive rights were first granted in the US by the Semiconductor Chip Protection Act of 1984. According to 17 U.S.C. § 904 , rights in semiconductor mask works last 10 years.
Multi-project chip (MPC), and multi-project wafer (MPW) semiconductor manufacturing arrangements allow customers to share tooling (like mask) and microelectronics wafer fabrication cost between several designs or projects. MPC consisting of five CMOS IC designs and few test N- and PMOS transistors for manufacturing acceptance

Hardmask materials can be metal or dielectric. Silicon based masks such as silicon dioxide or silicon carbide are usually used for etching low-κ dielectrics. [3] However, SiOCH (carbon doped hydrogenated silicon oxide), a material used to insulate copper interconnects, [4] requires an etchant that attacks silicon compounds.
