Xi'an is one of the important semiconductor industry bases in China. Although far from the coast, Xi'an still quickly seized the market hotspots. During the “Eleventh Five-Year Plan†period, Xi'an made a misplaced development in the integrated circuit industry, focusing on design, equipment, materials and navigation.
Mass production of a variety of independent innovation chips
Xi'an's first dislocation development area is the integrated circuit design industry. “Because design is an intellectual industry, Xi’an’s resources in this area are very advantageous.†Qi Jianwen, secretary general of Shaanxi IC Industry Association, introduced the reasons. “In this regard, we need to develop some high-end, independent knowledge. Innovative products of property rights, this is the aspect that we have spent a lot of energy in recent years.†After several years of development, the design industry has begun to take shape.
At the same time, a group of small and medium-sized innovative integrated circuit design companies that have been established and grown up in Xi'an have also launched some independent innovation chips with relatively high design levels in recent years. In the process of introduction, Zhai Jianwen highlighted the These products are used by the whole machine company.
In terms of communication, the broadband circuit-switched chip designed by the core is mainly used for optical switching equipment. At this stage, the switching speed has reached 80 GHz/s, which has been adopted by Fiberhome Communications, and is a main chip in the 烽ç«å…‰é€šä¿¡è®¾å¤‡. There is also an SDH single-chip system solution designed by Shenya, which has been adopted by telecom equipment companies such as Bell-Alcatel and Eastern Communications. In this year's very popular GPS field, Huaxun is the first company to launch baseband and RF chipset in China, and has been adopted by more than 10 companies for application.
In the field of consumer electronics, DTV's post-processing chip and IP core's Jiaoda Chuangxin, and the development of WAPI IP core, Xidian Jietong, etc., have become one of the few semiconductor IP suppliers with independent intellectual property rights in China, Hisense and Changhong. Hongwei and CLP Huada purchased their IP licenses respectively. In response to the demand of overseas markets, Xixin has launched a digital broadcast receiver baseband chip that meets the European standard, and has achieved a small-volume supply of 100,000 pieces per month. The servo device driver chip designed by Yatong is currently in a monopoly position in the domestic market. At the same time, it has also launched a power carrier communication chip, which has been adopted by many system manufacturers such as Shen Technology. For DVD products, Wansi successfully launched a series of 5.1-channel audio codec chips, which have been adopted by dozens of system manufacturers such as BBK and Hualu.
In addition, Xi'an has obvious advantages in analog circuit design. According to Yan Jianwen, there are currently a quarter of enterprises in the IC design base, that is, about 10 companies mainly focusing on power management design. The products they design include power management chips that are used in mobile phones, for example. The more mature products such as Deheng, Biaoxin, Yuanxiang and Yacheng have higher domestic market share in LDO chips. In addition, in the design of special processes such as BCD products, some companies have introduced PDP line scanning, column scanning, LCD driver and other chip products.
Develop demand for materials and devices
In addition to integrated circuit design, Xi'an's misplaced development also includes silicon materials, semiconductor devices and advanced semiconductor functional devices.
In terms of silicon materials, the foundation of the Tianhong Silicon Project was laid in September this year. This is a polysilicon project with a total investment of 3.7 billion yuan. It is planned to be constructed in three phases, with a capacity of 1,250 tons per period.
This is the first electronic grade polysilicon project in China for the production of 8-inch monocrystalline silicon. Its construction will provide high-quality polysilicon raw materials for China's electronic grade monocrystalline silicon and solar photovoltaic industry. According to Qi Jianwen, there are currently five large-scale silicon material processing enterprises in Xi'an, with an annual processing capacity of over 900 tons, and four solar photovoltaic module manufacturers including BP, with an annual production capacity of about 250 MW. In addition to the application of 4-8 inch electronic grade monocrystalline silicon products, the solar photovoltaic industry will be a big market. After the project is put into production, the scale of the silicon material industry in Shaanxi Province will reach more than 30 billion yuan.
LED local market space, large enterprise opportunities, long triangle lighting market facing bottlenecks need to be broken, LED growth slows down, manufacturers look for new market, world white LED market will grow by 16% in 2008.
