The first ArF photoresist production line by Nanda Optoelectronics has been officially put into production. It is estimated that the annual sales will reach 1 billion yuan after the project is fully operational.
Photoresist 光刻胶 is the core material for the production of integrated circuits, which mainly plays the role of “transferring the designed image from the template to the appropriate position on the wafer surface”. Therefore, the quality and performance of the photoresist have an important impact on the final product and performance of the chip. High-end types such as ArF photoresist almost rely 100% on imports.

It is the first time to verify the oblique detonation engine concept successfully with wind tunnel tests and the standing oblique detonation undergoes the initiation, transition and full-developed stages. The experiments also demonstrated well the criteria proposed in this paper. According to research progresses on oblique detonation engines, the Sodramjet engine is very promising for hypersonic airbreathing propulsion because that the engine system is simple in its structure, efficient in the thermo-cycle, broad in its operation Mach number range and low in aerothermodynamic heating load.
