Etching machine become single first in the block
During the fabrication wafer manufacturing, the use of special equipment mainly includes oxidation/diffusion equipment, lithography, etching equipment, cleaning equipment, ion implantation, thin film deposition equipment, chemical mechanical polishing equipment. The etching, lithography and thin film deposition, and called the three core semiconductor manufacturing process.
"Lithography" refers to the wafer at photoresist coated (or wafer) on the cover to make light of the stereotype, and then use ultraviolet ray through the lithography threatening the wafer for a certain time of exposure. Principle is to use ultraviolet light to make part of the photoresist metamorphism, prone to corrosion.
After etching is lithography, use corrosive liquid to that part of the photoresist erode away (short pimps), show at the surface of the wafer semiconductor devices and its connected graph. And then use another kind of corrosive liquid for wafer etching, formation semiconductor devices and circuits.
Micro to 2015, the company constantly improve the product craft, etching machine technology, has been in sync with the world advanced level, and with good marketing strategy, pushed out limitation etching machine sales in the United States, because the etching machine technology dominated by the United States, products, market share has been obvious.
Three years later, in 2018, according to IHS Market, the company is in broke d permitted and ace is strong, the monopoly of MOCVD equipment, the world's new gallium nitride leds - MOCVD Market share of 41%, the second half of the global accounted for more than 60%, single occupancy of products to the world's first.
Time came in 2021, micro etching mechanism in the process up to 5 nm, and successfully developed 3 nm etching machine, on January 22, 2022, the company disclosed in 2021 net profit, revenue increased 36.73% year-on-year, according to 3.108 billion yuan, a new sign of 4.13 billion yuan, rose 90.5%, an increase of 1.96 billion yuan. Reflect on the profits, in micro mother company belongs to the net profit of about 950 million yuan to 1.03 billion yuan, year-on-year growth of about 93.01% to 109.26%.
Except micro company in north China was the main etching machine of domestic manufacturers. But according to the consulting statistics, as of December 16, 2020, 348 sets of the Yangtze river stored accumulated bidding etching equipment, including the U.S. manufacturers Lam, Research the winning 187 units, accounting for 54% of total purchase amount.
Domestic manufacturers of micro, northern China, until tang company respectively the winning 50 Taiwan, 18, 13, the localization rate of 23.85%; Huahong factory of accumulative total 81 sets of bidding etching equipment, including LamResearch winning 45 units, accounting for 56% of total purchase amount, micro companies won the bid in the 15 units, for huahong factory of etching equipment, the second largest equipment suppliers, the proportion of the total purchase amount to 19%.
