Photoresist 16″China”s semiconductor industry loses color due to photoresist” (Science and Technology Daily, May 31)
Although my country has become a major semiconductor producer in the world, the overall industrial chain
of the panel industry is still relatively backward. At present, almost all photoresists for LCDs are imported,
and the core technology is still monopolized by Japanese companies such as TOK, JSR, Sumitomo Chemical,
and Shin-Etsu Chemical. Take BOE, which has certain competitiveness in the world, as an example. It has established
17 panel display production bases, 16 of which have been put into production. However, the photoresist used by BOE
for high-end panels is still provided by foreign companies. The main components of photoresist are polymer resins,
color pastes, monomers, photoinitiators, solvents and additives. The development involves many technical problems
, including oligomer structure design and screening, synthesis process determination and optimization,
activity Adjustments include monomer screening and control, color paste fineness control and stability, product formula
design and optimization, product production process optimization and stability, final use condition matching and tolerance
adjustment. Therefore, it is very technically difficult to independently develop and produce.
High voltage common rail system 17″The high-pressure common rail is useless, and domestic diesel engines are very
damaged” (Science and Technology Daily, June 4)
The electronically controlled diesel high-pressure common rail system is equivalent to the “heart” and “brain” of the diesel engine.
Its quality seriously affects the
use of the engine. The diesel engine industry is an important equipment foundation that promotes a country”s economic growth and
social operation. China is the world”s major market and producer of diesel engines, and in the domestic electronically controlled
diesel engine high-pressure common rail system market, companies such as Germany, the United States, and Japan account for the lion”s share
. Compared with the products of advanced foreign companies, there are still certain gaps in the performance, functions, quality
and consistency of domestic high-voltage common rail systems, and the cost advantage is not obvious.
