On May 11, Hangzhou Shilan Microelectronics Co., Ltd. (hereinafter referred to as "Shilan Microelectronics") issued a public announcement saying that due to the planning of a major matter involving the purchase of assets, the matter may constitute a major asset restructuring, and the stock has been suspended since May 12. Two months later, the asset restructuring officially surfaced. On July 12, Shilan Microelectronics issued another announcement that it had formally acquired Leshan Radio Co., Ltd. (hereinafter referred to as Leshan Radio, LRC).
Data show that Leshan Radio, formerly Leshan Radio Factory, was founded in 1970. Located in the historical and cultural city of Leshan, Sichuan Province, which is the center of China's western development, Leshan Radio is a comprehensive electronic enterprise with semiconductor discrete devices as its main products, and has a number of wholly owned and joint venture group enterprises. Since 1993, the annual sales revenue of discrete semiconductors has ranked the first in the country for 12 consecutive years. They are well-known high-tech enterprises and export earning enterprises in Western China.
Leshan Radio Co., Ltd. is mainly engaged in the design, manufacture and sale of semiconductor discrete devices. Its main products include small signal discrete devices and power semiconductor devices. The actual control of the company is Mr. Pan Minzhi.
Leshan Radio has Chengdu Advanced Power Semiconductor Co., Ltd., Leshan-Phoenix Semiconductor Co., Ltd., Chengdu Shuxin Integrated Circuit Design Co., Ltd., Leshan Feiji Mold Co., Ltd., Bridge Device Production Line, Plastic-encapsulated Device Production Line, Glass-encapsulated Device Production Line, Semiconductor Chip Manufacturing Branch and other manufacturing bases. 。
Chengdu Advanced Power Semiconductor is located in the export processing zone of Chengdu Hi-tech West District. It is an independent subsidiary of Leshan Radio, covering an area of 166 acres (27 acres). It is mainly planned to produce SMD and other new packaging devices. The company was founded in October 2009 and put into operation in November 2010. The total investment of the first phase project is about 600 million RMB. It has the most advanced semiconductor packaging and testing equipment and technology in the world. The company's main customers include: Samsung, Huawei, Foxconn, Jeep, Osram and other well-known enterprises.
Leshan-Phoenix, founded in 1995, is a Chinese semiconductor packaging and testing enterprise jointly established by American Ansenmei Semiconductor Company (80% holding) and Leshan Radio (20% holding). At present, Leshan-Phoenix Semiconductor's total investment has exceeded 509 million US dollars, with a total capacity of 400 billion, has three post-process packaging and testing plants, and the total number of employees has reached 2600. At present, the company's main products are surface mounted discrete semiconductor devices, including SOT/SOD/SC/TSOP/DFN and other packaging types, which are mainly used in electronic and electrical equipment, automotive industry, communication systems, broadband data technology, computers and household appliances, and has built SOT series, SC series, SOD series and other emerging surfaces. The production line of mounted devices has a capacity of 28 billion.
Chengdu Shuxin is a FABLESS company which designs and manufactures analog integrated circuits. It is located in Chengdu Hi-tech Incubation Park. Its main products are LDO series, voltage detection and reset circuit, single gate logic and so on.
Leshan Feiji is a joint venture between Bill Semiconductor Industries, a Dutch semiconductor precision die manufacturer, and Leshan Radio Corporation. It is mainly engaged in the design and manufacture of semiconductor precision packaging die, shear forming die, various precision parts and special machinery and equipment. It is worth noting that Leshan Feijiao is also the first ultra-high precision processing plant in China to reach 1 micron.
Bridge device production line, plastic packaging device production line, glass sealing device production line and semiconductor chip manufacturing branch are the main discrete device manufacturers of Leshan Radio. The bridge device production line mainly produces high-quality half-bridge, full-bridge, automobile bridge and other products, and is one of the main manufacturers of bridge devices in China; the plastic-encapsulated device production line mainly produces SMA chip diodes, 1-6A ordinary and fast rectifiers, TVS, Schottky and other products; the glass-encapsulated device production line produces regulators, switching tubes. Two-way trigger tube and other products.
Major global discrete device suppliers
Semiconductor discrete devices in the world are monopolized by the United States, Japan and Europe. Joint ventures are the main domestic suppliers. Manufacturers mainly include: U.S. Department in the world of power IC, TI, IR, Diodes, Fairchild, Ansenmei, Vishay and so on; European Power Semiconductor Trident, Infineon, NXP, ST, etc; Japanese discrete device corps, Toshiba, Reza, Rom, Fuji Motor, etc; Taiwan, China, Licast, Fuding Advanced, Maoda, Chong, etc. Trade and so on.
In recent years, the global voice of China's semiconductor discrete devices is steadily improving, and it has become the largest discrete device market in the world. At present, Guangdong, Jiangsu and Shanghai are among the top three exporters of semiconductor discrete devices in China. The major exporters of semiconductor discrete devices in China are still coastal provinces, with a large number of manufacturers, mainly producing low-voltage products. However, domestic manufacturers have made breakthroughs in high-power device IGBT, and have entered the field of new materials SiC and GaN.
Local discrete device manufacturers mainly include Yangjie Technology, Huawei Electronics, Suzhou Gouteng, Taiwan-based shares, Kaihong Technology, Hualian Electronics, Leshan Radio, etc. The following are the main manufacturers of semiconductor discrete devices in China (ranked in no particular order):
