ExxonMobil to start production of 99.999 percent ultra-pure IPA to support semiconductor manufacturing

Share:

With growing demand for U. S.-made semiconductors and increasingly stringent purity requirements for the latest chips, ExxonMobil will expand its isopropyl alcohol (IPA) portfolio in 2027 to begin production of 99.999 percent ultra-pure IPA in Baton Rouge.

The company's entire IPA supply chain, from raw materials to finished product synthesis, will be based in the United States, thereby facilitating the production of high-purity IPA and strengthening our domestic supply chain to support U.S. industry. While 99.9 percent IPA is ideal for hand sanitizers and household cleaning solutions, next-generation semiconductors require 99.999 percent IPA to avoid damaging delicate microchips. As chips develop into smaller devices (sometimes as small as 2 nanometers, which means that 150,000 chips can be placed on a grain of salt), higher IPA purity becomes critical. These chip nodes or information centers compressed into small devices require ultra-pure IPA to dry the wafer surface, reduce impurities, and prevent damage. Advanced chip manufacturers rely on this high-purity IPA to minimize defects in sensitive circuits. Producing IPA with a purity of 99.999 percent is the next step in the company's development with this market. The semiconductor chip manufacturing industry needs a reliable domestic supply of ultra-pure IPA, and the company is committed to providing this supply. ExxonMobil is upgrading our plant in Baton Rouge, the world's largest isopropanol plant 1, to meet growing demand through 2027.
