Shanghai Qianghua

In April, 1999, Shanghai Qianghua Quartz Products Factory was officially founded amid the tide of the times.

In February 2009, Qianghua Industrial was founded. In the same year, the new Jinshan factory was officially put into operation.

In June 2011, the Phase II factory of Qianghua Jinshan was put into operation. It houses two major divisions: thermal processing and mechanical processing, with business focused on the localization of quartz products for integrated circuits in China.

Qianghua joined the China Integrated Circuit Materials Industry Technology Strategic Innovation Alliance, participating in the formulation of national standards for quartz products used in semiconductors, and accelerating the company's pace in the localization of semiconductor quartz products.

The company passed the localization certification for quartz devices under the National Major Science and Technology Project entitled Ultra-large Scale Integrated Circuit Manufacturing Equipment and Complete Set of Processes (the 02 Special Project) of SMIC. It has become a qualified supplier for the localization of quartz devices, ranking as the first domestic Chinese-funded enterprise to pass SMIC’s certification for quartz products, and also China’s first non-original manufacturer with OEM certification to supply FAB fabs.

The company completed the joint-stock system reform at the end of 2017 and was renamed Shanghai Qianghua Industrial Co., Ltd. On August 2, 2018, the company’s shares were officially listed and publicly traded on the National Equities Exchange and Quotations (NEEQ). The stock code is 872927, with the stock short name Qianghua Shares.

The company planned to launch the project of the Lingang production base for key new materials of core integrated circuit equipment, and signed relevant agreements with the Lingang Administrative Committee, with a planned investment of 550 million yuan. In the same year, the company initiated the acquisition of Quartztec, one of the three major quartz product manufacturers in Europe.

The company undertook and successfully tackled the national key project Quartz-related Devices for Large-Diameter MOCVD Processes of Integrated Circuits, realizing the localization of high-process diffusion technology for integrated circuit manufacturing.

In July 2023, the company successfully completed the holding acquisition of British quartz products enterprise QUARTZTEC. It became the first domestic Chinese-funded quartz enterprise in China to complete an overseas merger and acquisition, further expanding its markets in Europe and America and laying a solid foundation for the company's global layout.

In September 2023, the reconstruction and expansion of the company's Jinshan Factory was completed. The new 12-inch high-purity and high-precision (SHP) thermal processing workshop was officially put into production, enhancing the company's service capacity for 12-inch semiconductor quartz products.

The Phase II factory of the UK subsidiary QUARTZTEC has been put into operation, further enhancing the company's overseas production capacity and service capabilities.

In 2025, the company's Lingang Production Base Project for Key New Materials of Core Integrated Circuit Equipment was officially put into operation, marking an important milestone in the company's strategic layout.
