ENTG

Entegris, Inc.

A maker of the ultrapure materials, chemicals, and handling gear that go into making computer chips, Entegris keeps silicon wafers clean and flat during fabrication, supplying things like CMP slurries, specialty gases, and wafer carriers to chipmakers worldwide. The company traces back to 1966's Fluoroware, which made Teflon-based containers for early microelectronics, and took its current name in 1999 after merging with EMPAK. Fun fact: "Entegris" blends "integrity" and "ingenuity" — a nod to keeping microscopic circuitry flawless.
