Global Top 4 Companies Accounted for 60% of total Soda Photomask market (QYResearch, 2022) | |
A photomask is an opaque plate with holes or transparencies that allow light to shine through in a defined pattern. They are commonly used in photolithography and the production of integrated circuits (ICs or "chips") in particular. Masks are used to produce a pattern on a substrate, normally a thin slice of silicon known as a wafer in the case of chip manufacturing.Photomask Materials The most common types of glass for manufacturing masks are Quartz and Soda Lime. Quartz is more expensive, but has the advantage of a much lower coefficient of Thermal Expansion (which means it expands less if the mask gets warm during use) and is also transparent at deeper Ultraviolet (DUV) wavelengths, where Soda Lime glass is opaque. Quartz needs to be used where the wavelength being used to expose the mask is less than or equal to 365nm (i-line). The global key manufacturers of Soda Photomask include Toppan, Photronics, ShenZheng QingVi, Taiwan Mask, Newway Photomask, etc. In 2022, the global top four players had a share approximately 60.0% in terms of revenue.
