photomask is an opaque plate with transparent areas that allow light to shine through in a defined pattern. Photomasks are commonly used in photolithography for the production of integrated circuits (ICs or “chips”) to produce a pattern on a thin wafer of material (usually silicon).
Several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set.A set of photomasks, each defining a pattern layer in integrated circuit fabrication, is fed into a photolithography stepper or scanner, and individually selected for exposure.
In multi-patterning techniques, a photomask would correspond to a subset of the layer pattern.In photolithography for the mass production of integrated circuit devices, the more correct term is usually photoreticle or simply reticle.
In the case of a photomask, there is a one-to-one correspondence between the mask pattern and the wafer pattern. This was the standard for the 1:1 mask aligners that were succeeded by steppers and scanners with reduction optics.
Global photomask coating system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Toppan Carves Out Semiconductor Photomask Business to Launch New Company. Toppan, a global leader in communication, security, packaging, décor materials, and electronics solutions, has entered into a share transfer agreement to carve out its semiconductor photomask business and establish a new company, Toppan Photomask Co., Ltd.
(Toppan Photomask), with independent Japanese private equity company Integral Corporation (Integral) as an investment partner.
Toppan Photomask begins operations today as a joint venture between Toppan and Integral. The company will drive further growth and strengthen competitiveness as an independent business entity that continues to support the rapidly growing semiconductor industry.
As digital innovation accelerates in diverse markets due to the evolution of technologies including artificial intelligence, automotive, power, and 5G networks, the global semiconductor market continues to expand at a rapid pace.
Against a backdrop of a global shortage of semiconductors, manufacturers are moving to bolster production capacity, which is in turn driving unprecedented demand for photomasks, essential components for semiconductor fabrication.
