Photomask is one of the key materials in semiconductor chip and display panel manufacturing . In recent years, with the rapid development of China's semiconductor and display industries, the demand for photomask has been increasing year by year. Photomask has high technical threshold, high-end photomask mostly depends on import, so that it increases the cost of photomask, and chrome mask blank is the basis of the photomask materials.we provides high quality raw materials for domestic photomask production enterprises , the industry chain will be improved. In order to create a high precision, low defect mask blanks, we has set up a professional research and development team with the world's leading production technology. Optrytech adopts the world's most advanced production equipment ,testing equipment, grade 10 purification workshop. we has the scientific, strict, perfect inspection system and after-sales system . we provides high precision and low defect products  for “Made in China”, we always insists on quality first and is based on sincerity.

What is an optical mask

    A structure in which various functional patterns are fabricated and precisely positioned on a film, plastic or glass substrate for selective exposure of a photoresist coating, known as a lithography reticle.
    The fabrication process of semiconductor integrated circuits usually requires multiple photolithography processes to dig various doping windows, electrode contact holes on the dielectric layer on the surface of the semiconductor crystal, or etch metal interconnect patterns on the conductive layer. The photolithography process requires a complete set of photocopying masking stencils with specific geometries that can be accurately registered with each other (several pieces to as many as a dozen pieces).

- The photomask is a high-precision version with microcircuits engraved on it. It is made of a quartz plate or glass plate with a flat surface and a layer of chromium. The residual chromium part after etching is the designed microelectrogram. This method of plate making is called light transmission in the mask industry.
