In the introduction of domestic productionLithography machineLet's take a look at the stages of developmentRear end lithography machine, because in this area, domestic technology is not bad. ShanghaiMicroelectronicsYesRear end lithography machineThe leader in the field, the global market share has reached 37%, and the domestic market share is 85%. Many global packaging and testing companies choose to start from ShanghaiMicroelectronicsBuy hereRear end lithography machinefor chip packaging. Rear end lithography machinecomparativelyFront-end lithography machineThe threshold is low and the difficulty is small, which is also the reason why domestic technology can make breakthroughs.
Front-end lithography machineYesLithography machineIt is divided into different types, including I-line, G-line, KRF, ARF, etcarfiand eUV lithography machineasmlIt is the dominant player, accounting for more than 80% of the global market share. ARF is a common dry typeLithography machine, which supports up to 65nm. WhilearfiIt is immersionLithography machine, with a maximum process support of 7nm. As for eUV lithography machine, currently only available worldwideasmlAble to be manufactured, the technology is used below the 7nm process. In addition,arfiLithography machineThe manufacture of is also onlyasmlwithNikonTwo businesses.
Attached below is a picture, from which it is obvious that the four mainstream companies are inFront-end lithography machineGap in the level of technology. asmlAt the top of the list, the technology is the most advanced, followed byNikon, reaching the high-end level, iearfiTechnology. ShanghaiMicroelectronicswithCanonIt is in the lower end of the field and has always been stagnant in the 90nm process stage. Of course, there are also some netizens who claim to be domesticLithography machineThe level of technology is not just stuck at 90nm, but it has not been disclosed yet. This view varies from person to person, and we can only analyze it based on publicly available data.
To sum up, the wholeLithography machinefield, domesticRear end lithography machineThe technology is already in the lead, and the main thing that needs to be broken through isFront-end lithography machine。At present, the ARF technology has been mastered in China, and the next step is to make a breakthrougharfitechnology, that is, immersion technology. And when it can break through, it still depends on ShanghaiMicroelectronicsefforts. We look forward to achieving this breakthrough as soon as possible, and although the technology is still stuck at 90nm, it only takes one breakthrougharfitechnology, it is expected to reach the process level of 7nm. In this way, the US blockade policy will be a complete failure.
DomesticLithography machineWhat stage has it reached?Judging by the current situation, inRear end lithography machinefield, the country has achieved a leading position, especially ShanghaiMicroelectronicsSuccessful performance in the global market. However, forFront-end lithography machineIn other words,asmlIt almost monopolizes the entire market, and the country is in a relatively backward state. The goal is to break through the immersion technology and realize the transition from ARF toarfito reach a higher level of craftsmanship. For domesticLithography machineIndustry-wise, breakthroughsFront-end lithography machineThe field is full of challenges, but it is also full of opportunities and potential. Strive to break through the technical bottleneck, improve the ability of independent innovation, domestic productionLithography machineWe will be able to develop by leaps and bounds and become world-classLithography machineManufacturing powerhouse.
