At present, the rapid development of smartphone technology has caused a global phenomenonTechnologycircles, in particularChipsAdvances in technology. And in the face of fierce competition and external restrictions, domesticTechnologyThe improvement of strength is particularly urgent. The so-called facing difficulties is not only to catch up with the pace of technological development, but also toCriticalAchieve independent innovation in the field of technology, get rid of external constraints, and create ChinaTechnologyA new chapter. Although people are concernedChipsAdvances in design and manufacturing, but still have some supportChipsManufacturedCriticalFactors are overlooked. These factors include:ChipsManufacturing supports technologies and materials that play a vital role throughout the value chain.
InChipsmanufacturing process, exceptChipsIn itself, the quality of the supporting materials and technologies is also crucial. For example, high-purity silicon wafer pairsChipsPerformance is critical, and achieving this high purity is a technical challenge. Although some progress has been made in the production of silicon wafers in certain purity grades, it is necessary to produce higher performanceChipsThe extremely high purity silicon wafers that we still faceTechnical barriers。In addition,LithographyYesChipsIndispensable to manufacturing, it can accurately draw complex circuit patterns on silicon wafers. However, the domestic high-endPhotoresistThe production capacity is still not enough to meet the demand, and most of it still needs to be imported. This dependency problem limits China at the high endChipsDevelopments in the field of manufacturing.
Expanding: To be inChipsBreakthroughs have been made in the field of manufacturing, in addition to the focusChipsIn addition to technological innovation in design and manufacturing, it is also necessary to strengthen itCriticalResearch and development supported by materials and technology. High-purity silicon wafers as:ChipsThe basic material for the manufacture of the pair, the process of its preparationChipsPerformance has a critical impact. On the basis of the production of silicon wafers of a certain purity level in China, how to break through the technical difficulties of higher purity requirements has become a difficult problem to be overcome. In addition,LithographyYesChipsAn indispensable process in manufacturing, it is mainly achieved by projecting the circuit pattern onto the silicon waferChipsof manufacturing. At this stage, the domestic high-endPhotoresistThe ** still failed to meet the market demand, which will also become domesticChipsManufacturing capacity improvementCriticalOne of the bottlenecks.
In addition to the material andCriticalThe ability to independently manufacture chemicals and domestic production tools is also an important criterion for judging the independence of a country's semiconductor industry. Lithography machineAsChipsOne of the core equipment of production, its precision requirements are extremely high, but it is currently high-end in the worldLithography machineThe market is almost monopolized by a few countries, which is essential for the realizationChipsIndustrial autonomy is a major challenge. Domestic independent research and development and production of high-endLithography machineImperative.
Expanding:ChipsThe production equipment required in the manufacturing process is also an important factor affecting the level of industrial autonomy. toLithography machineFor example, as one of the most core and highest-precision equipment, it occupies a dominant position in the international market. However, at the moment the global high-endLithography machineThe situation of the market is almost monopolized by a few countries, which makes itChinese chipsThe industry is facing serious challenges. To think inChipsThe whole industrial chain of manufacturing is independent, and domestic R&D and manufacturing are high-precisionLithography machineIt has become a top priority.
In the current globalTechnologyIn the competition, China is inChipsThe independent development of the field faces many challenges and constraints, but it also has great potential and opportunities for development. To be realizedChipsIn addition to paying attention to the autonomy of the industryChipsIn addition to the improvement of design and manufacturing technology, it is also necessary to further increase investment in research and development of materials, technical support and production equipment, build a complete industrial chain, strengthen international cooperation and make breakthroughsTechnical barriers。Only through continuous efforts and innovation,Chinese chipsTechnology can leap against the trend and achieve real independent innovation and leading edge.
