SemiconductorsThe industry has always been consideredTechnologyThe "corner overtaking" in the field, people who have a place in this field, such as Liang Mengsong, once pointed outSemiconductorsThe field does not allow "overtaking in corners". However, there is no shortage of voices in China who believe that we are expected to achieve technological transcendence in this complex field. And at this time, it is the time when the United States is rightSemiconductorsRestrictions on exports, but the domestic has successfully developed 7Nanoof the advancedChips。Many foreign onesSemiconductorsThe giants also believe that under the ban of the United States, China'sChipsThe industry will rise rapidly. However, the latest key data reveals a reality: inSemiconductorsIn manufacturing, the country is still interested in products such as silicon wafers, electronic special gases andPhotoresistand other major raw materials are heavily dependent on imports, with a self-sufficiency rate of less than 10%. This means that domestic chips are still subject to key raw materials from abroad and cannot be fully independent and controllable. In such a situation, the "fire" of domestic cores may be too early.
DomesticSemiconductorsAll kinds of raw materials required in manufacturing, such as silicon wafers, electronic special gases, etcPhotoresistetc., the self-sufficiency rate is less than 10%, which makes the domesticChipsThe industry is still subject to foreign restrictions on key raw materials. Taking silicon wafers as an example, the size of large silicon wafers manufactured in China is only 300Nano, the market share is low, it is difficult to compete with foreign countries; And whereasPhotoresistIn other aspects, domestic manufacturers mostly stay at 90NanoThe level of technology is more difficult to get involved in more advanced technology. Therefore, whether it is the self-sufficiency rate or the process level, there is still a large gap between domestic chips and foreign countries.
Expansion: silicon wafer asSemiconductorsCritical materials in manufacturing, their quality and specificationsChipsPerformance has a direct impact. At present, although China has made some progress in silicon wafer production, it is still difficult to compare with foreign giants. WhilePhotoresistIt is an indispensable material in the manufacturing processChipsThe manufacturing process plays a vital role. The high level of domestic dependence on these key raw materials underscores our inSemiconductorsIn this field, it is still necessary to increase the degree of autonomy of the industrial chain.
In addition to the lack of self-sufficiency, domesticSemiconductorsThere is also a large gap between the technical level of materials and foreign first-class manufacturers. For example, the process technology of domestic manufacturers is mostly concentrated in the lower onesNanolevel, it is difficult to reach the international advanced level. For photomasks,PhotoresistThere are also difficulties in the coverage of various materials such as supporting reagents and polishing pads, and technical barriers cannot be ignored. In the current market size is not large but varied, domestic manufacturers must make a trade-off between R&D investment and market prospects, and are less willing to investSemiconductorsIn the field of raw materials, it is difficult to promote the overall technological upgrading of the industry.
Expanding: The level of technology is the way to judge a countrySemiconductorsAn important sign of strength, and the country is inSemiconductorsThere is still an obvious gap between the technical level of materials and foreign countries. Especially in the wafer production processPhotoresistIn terms of research and development of formulas and other key materials, China still needs to increase investment and breakthroughs. Although the market scale is relatively limited, the preparation and application of different types of materials is still an important part of promoting the progress of the industry, and domestic manufacturers must make more efforts to expand the scope of technology.
While domestic chips have made certain breakthroughs, they are still facing many challenges and problems. to domesticSemiconductorsThe lack of self-sufficiency in raw materials and the technological gap are examples of these problemsChina ChipGloballySemiconductorsChaincompetitive position. To be realizedChipsFor the sustainable development of the industry, domestic manufacturers need to increase investment in the research and development of key raw materials and the improvement of process technology, and do a good job in long-term planning and layout. At the same time, we also need to look at our own development status rationally, take precautions, and move forward in a low-key manner, so as to better win future development opportunities.
