In January 2025, Chemtronics acquired J3, a wafer processing company, 
thereby expanding its presence in the semiconductor business sector.
J3 manufactures wafers, which are the basis of semiconductors. 
In particular, J3 provides wafer reclamation services, creating economic and social value.
								

												The recent increase in demand for semiconductors for 
smartphones and vehicles has led to a rise in the use of wafers. 
In the mid- to long-term, demand for data storage devices such 
as servers and storage systems is expected to continue, 
which will lead to the continued growth of the wafer and 
reclaim markets.
											
												In line with this outlook, Chemtronics provides wafer reclaim 
service, leveraging our decap line and wastewater treatment 
infrastructure.
