[News] Shortage in Global Semiconductor Photomasks! Prices Expected to Rise in 2024

According to South Korean media The Elec’s report, due to strong demand from Chinese chip manufacturers and wafer foundries, the shortage of photomasks in the market has not eased, and it is anticipated that prices will rise in 2024.

The report notes that most photomask manufacturers, including Japan’s Toppan, DaiNippon Printing, and the U.S.’s Photronics, are currently operating at full capacity with a utilization rate of 100%. Some Chinese chip companies are even willing to pay additional fees to expedite delivery schedules.

In the field of integrated circuits, the function of a photomask is similar to the “film” in a traditional camera. With the collaboration of exposure and development processes in photolithography machines and photoresist, the pre-designed patterns on the photomask are transferred to the photoresist on the substrate, enabling mass production through image replication.

Photomasks play an indispensable role in the semiconductor chip manufacturing process, especially in advanced processes where more intricate circuit patterns require multiple layers of photomasks to aid production. For example, mature processes may require around 30 photomasks, while the latest advanced processes might demand as many as 70 to 80 photomasks to handle.

Currently, Chinese foundry giant SMIC employs Deep Ultraviolet (DUV) technology to produce 7nm chips. Compared to Extreme Ultraviolet (EUV), DUV requires more photomasks for the fabrication of multiple circuit patterns.

Toppan Printing, in its latest quarterly financial report covering July to September, anticipates a continual increase in demand for photomasks throughout 2023. DaiNippon Printing expressed agreement with this assessment in its half-year financial report for the period from April to September.

The graphic dimensions, precision, and manufacturing technology requirements of semiconductor photomasks continue to increase, with only a 3% domestication rate for high-end photomask versions in China. In the preparation of photomasks, the Chinese semiconductor photomask industry faces a situation where high-end equipment and materials are dominated by foreign manufacturers.

In the photomask industry chain, the upstream sector primarily involves equipment, substrates, light-blocking films, and chemical reagents; the midstream sector is photomask manufacturing, and the downstream sector includes chips, flat panel displays, touchscreens, circuit boards, and more.

The urgent demand for domestic substitutes for photomask versions is apparent, and the revenue scale of Chinese photomask manufacturers still has a considerable gap compared to leading overseas manufacturers.
