What is chrome mask blank/photomask blanks?
English name : Photomask blanks /Chrome mask blanks /Photolithography mask layers
Chrome mask blanks plate is a hard-surface photomask material, that is, a photomask base plate, which is the mainstream photosensitive material (equivalent to photographic photosensitive film) for current and future microfabrication photomask production. It is formed by depositing a chromium nitride-chromium oxynitride film on a flat, high-quality glass substrate by DC magnetron sputtering (SP), and then coating a layer of photoresist on it. Etch (also known as photoresist) or electron beam resist to make a uniform chrome plate.
The uniform chrome plate has the characteristics of high photosensitivity, high resolution, low defect density, good wear resistance, easy cleaning, long service life, etc. It is currently widely used in IC, LCD, PCB, PDP, DOT and other product masks Production of film.
1. Display devices such as FDP, represented by LCD, are developing into larger screens and wider viewing angles, and are rapidly developing into high-definition and high-speed displays.
2. The electronic components represented by (semiconductor chips) are miniaturized and refined, and the manufacturing process becomes more complicated. The elements that meet these requirements are the production of fine and high-dimensional components and electronic circuit patterns. At present, most electronic circuit diagrams are produced. The pattern plate prepared by the photolithography method is called a photomask, and the uniform chrome plate (photomask base, blank mask) is used as the base of the photomask, and its production requirements are extremely high. Next Let's find out together.
3. The manufacturing process of the photomask chrome plate: cleaning, coating, and gluing (as shown in the figure). After the production is completed, the pattern is produced by electron beam lithography/laser direct writing lithography.

4. Product application
Chrome maskblanks plate is mainly used in: semiconductor chip manufacturing, display panel industry, optical industry mask, semiconductor display device, PCB and other industries. Photomask is one of the key materials in the manufacturing process of semiconductor chips and display panels. In recent years, China The semiconductor and display industries are developing rapidly, and the demand for photomasks is increasing year by year. The technical threshold of photomasks is high. Most of high-end photomasks rely on imports, which increases the production cost of products. Chengguang provides high-quality raw materials for domestic photomask mask manufacturers to make the industry chain more perfect. In order to create high-precision, low-defect blank photomasks, the company has established a professional scientific research team with world-leading production technology. The company adopts the world's most advanced production equipment, testing equipment, ten-level purification workshop, scientific, strict and perfect inspection system and after-sales system. In order to provide high-precision, low-defect products made in China, Optrytech always insists on quality first and honesty.
