Propylene Glycol Monomethyl Ether Acetate

[INQ. NO. 2202M16] PGMEA (Propylene Glycol Monomethyl Ether Acetate, cas no. 108-65-6) varies according to the purity, but the general purity (99.7%) is a cleaning solvent for printer boards, a precision cleaning solvent, and a solvent for paint. High purity (99.95%) is used as a PR thinner for LCD substrates, and ultra-high purity (99.99%) is used as a PR thinner for semiconductors.
During the semiconductor process, PGMEA is used as a thinner in the RRC (Reducing Resist Consumption) process, which applies a thinner first before raising the PR during the photolithography process, and the EBR (Edge Bead Removal) process that removes the PR solution attached to the edge of the wafer. The use of lithography processes of less than 10 nm has been expanded and its usage is gradually increasing.
As the semiconductor manufacturing process is refined from 10nm -> 7nm -> 5nm -> 3nm -> 2nm, the distillation process and the impurity removal process have been developed to match the semiconductor microprocessing process to produce ultra-high purity PGMEA.

JAEWON INDUSTRIAL CO., LTD. has since its foundation in September 1987 at Yeosu Industrial Complex, been engaged in petrochemical and electronic material production, which requires high-standard distillation technology for value-added production.
JAEWON INDUSTRIAL deals with a large variety of the high-value petrochemical refining business and industrial grade alternative fuel production using renewable resources.
