Microelectronics - Lessons learned: the installation of a 300 to 600 GPM Semiconductor High Purity Water System

0

The life of a high-purity water treatment project may be compared to roll-ing a boulder down a dome-shaped hill (1). The project gets rolling with a fairly small nudge. Once it is rolling, however, it takes a great deal of effort (time and money) to change the direction or go back up the hill. The project to design, build, install, and commission the 'E' high-purity water system at VLSI Technology's San Antonio, Texas, manufacturing site followed this model. Now that we are at the bottom of the hill with a functional system, we will take a look back to see the major decisions and players that made the new system successful.

Every custom water system carries a 'flavor' from the owner. VLSI Technology Inc. makes custom and semi-custom integrated circuits (ICs) primarily for the digital communications and graphics industries. VLSI currently has one wafer fabrication plant for production quantities of ICs. This plant in San Antonio has approximately 60,000 square feet of Class 1/Class 100 cleanroom space making a variety of products with mini-mum line sizes of 0.8 micron (pm) to 0.2 pm on 150-millimeter (mm) (6 inch) wafers. The plant is currently converting to 200-mm (8 inch) wafers. VLSI had 1998 revenue from continuing operations of $548 million and employs about 2,200 people worldwide of which 600 to 700 work in San Antonio.
