The Science and Technology Innovation 50 Index was re-evaluated, and the company was not well evaluated online. In addition, Qingyi Optoelectronics has problems such as relying on foreign manufacturers for its main raw materials, and there is a gap between its products and foreign counterparts.
Data show that from 2016 to the first half of 2019, the amount of raw materials purchased by Qingyi Optoelectronics from its top five suppliers accounted for 82.98, 81.60, 84.02 and 85.06 of the total raw material purchases in the current period.
Taking the industrial chain as an example, the raw material of the mask is the mask substrate, which is a glass substrate coated with photoresist and chrome plating. Since photoresist has a certain timeliness, once it fails, it will affect product quality. Qingyi Optoelectronics does not have the ability to apply glue, and some foreign competitors have already deployed upstream.
1. Introduction to Qingyi Optoelectronics
Qingyi Optoelectronics is mainly engaged in the research and development, design, production and sales of masks. It is the earliest and largest mask production company in China. One of the enterprises. Customers include BOE and SMIC
What is a mask? Mask, also known as photomask, photomask, photolithography mask, mask, etc., is a pattern transfer tool or master in the microelectronics manufacturing process and is used for mass copy production in the downstream electronic component industry. The mask plays a key role in connecting the previous and the next in production and is an indispensable and important link in the industrial chain.
According to reports, as of the signing date of the prospectus, Qingyi Optoelectronics has obtained 24 invention patents and independently applied for, undertaken and compiled a national electronics industry standard, "Mask Specification for Thin Film Transistors (TFT)" .
Qingyi Optoelectronics’ customers include many well-known electronic companies, including BOE, Tianma, CSOT, Innolux, Hannstar Color Crystal, Longteng Optoelectronics, Truly, CEC Panda, Visionox, etc., and in the field of semiconductor chips, they include Aike, Qibang Technology, Changdian Technology, SMIC, Silan Micro, Intel, etc.
