## About

Based in Hefei, China, and established in 2018, ADChem Semi-Tech. Inc., trading under the name Adchem, is a new material company that engages in the R&D, production, and sale of semiconductor film precursors. Its team has R&D, and management experience in Fortune 500, such as Apple, Applied Materials, and Evonik Specialty Chemicals, Germany. In July 2019, it received the first precursor order. Besides, it has R&D centres, production bases in Tongling, and sales centres in Shanghai and Hefei. In September 2025, it closed a round of strategic investment from new investor Zhonghua Jianxin Investment Management.

Adchem provides atomic layer deposition (ALD) precursors and chemical vapor deposition (CVD) precursors. The ALD precursors include Trimethylaluminum (TMA), Dicarbonylcyclopentadienyl cobalt (Ba(iPr3Cp)2), Copper hexafluoroacetylacetonate (Cu(hfac)2), Cyclopentadienylindium(I) (CpIn), trimethylation (TMSb), Diethylzinc (DEZ). The ALD is a key process in fabricating semiconductor devices, and part of the set of tools for synthesizing nanomaterials. The CVD is a vacuum deposition method, and the process used in the semiconductor industry to produce thin films. 

The company generates revenue from the sale of semiconductor precursors to integrated circuit fabs and equipment manufacturers.

Adchem plans to use its latest strategic investment to expand its production capacity, accelerate the development of high-k and advanced metal-based precursor products, and complete construction of its second production base in Hefei to meet increasing demand from memory and logic semiconductor manufacturers.
