Shenghui Integration was established in 2003. Its main business is a clean room project known as the "chip delivery room", covering clean room factory construction planning, design suggestions, equipment configuration, engineering construction, engineering management and maintenance services and other related services. The company initially mainly served the downstream precision manufacturing field, and later entered the electronics industry with more stringent requirements for the production environment. With market recognition in the panel processing and chip packaging and testing, the company has further grown and strengthened in the semiconductor field, entering IC production, silicon wafer manufacturing and other links.
has been deeply engaged in the industry for 20 years. The company has the ability to "engineering construction design + procurement + construction + maintenance" EPCO, and has successfully implemented more than 300 clean room-related projects above a certain scale, including nearly 50 clean room projects of level 100 or above. The "Shenghui" brand is well-known in the industry.

is also one of the few companies in the industry that have the highest level of clean room construction capabilities. The company has ISOClass1 level clean room construction capabilities and experience, and has mastered the control capabilities and experience of ±0.1℃ temperature and ±2%RH humidity, as well as PPT level AMC control capabilities and VC-C level micro vibration control capabilities. Based on the country's leading process technology, the company has a high market share in the clean room engineering service field of the high-end electronics industry. World-renowned semiconductor companies such as Foxconn Group, Wistron, SMIC, Sanan Optoelectronics, and Crystal Integration were all customers of the company.
In recent years, under the trend of domestic semiconductor substitution, the company's performance has shown accelerated growth. From 2019 to 2021, the expressway achieved operating income of RMB 934 million, RMB 1.096 billion and RMB 1.702 billion, respectively, and the net profit attributable to shareholders of RMB 73.3472 million, RMB 81.7347 million and RMB 123.6038 million respectively during the same period.

In the long run, with the rise of my country's high-end manufacturing industry and the trend of domestic production in the semiconductor industry, the domestic clean room engineering industry is expected to expand rapidly.
