Jiangsu Handtop Optical Materials Co., Ltd. was established in December 2014 with a registered capital of 100 million yuan. It is an early domestic enterprise engaged in the research and development and production of high-end photoresists. Its core team is composed of high-level overseas returning entrepreneurs and domestic and foreign experts. The company is committed to independent R&D, production and sales of high-end photoresist products and related materials used in the IC manufacturing process. At present, it has successfully developed four series of photoresist products of I-line photoresist, K r ​​F photoresist, A r F photoresist and electron beam photoresist, which have been evaluated or sold in many domestic units and IC factories. An industrial chain for the development and production of monomers of the group company, polymer resins and photoresists of Hantuo has been formed, so that the raw materials are guaranteed, the quality can be traced, and the cost can be controlled. The company is making every effort to promote cooperation with domestic and foreign IC manufacturers, and work hard for the domestic chip business and the localization of lithography materials.
