Intel, based in Santa Clara, Calif., first came to Hillsboro in 1974, buying the 35-acre parcel that became Aloha, because all its existing factories at the time were along California fault lines, the San Andreas Fault and Hayward Fault.
Intel's silicon development teams ran out of space at Aloha by the 1990s, so started building Ronler Acres, a 300-acre site a few miles away. At Ronler, Intel researchers study new ways to shrink chip transistors, to help make gadgets smaller, cheaper and faster.
Ronler's facilities are connected by a maze of stainless steel pipes and lattices, dotted with tall silos filled with gases and surrounded by a utilities building, water purification plants and an electrical substation.
In February 2011, President Barack Obama toured Intel's facilities in Hillsboro to highlight the company's investments in US manufacturing. Here's a chip wafer he signed during the visit, which Intel has framed at the lobby of its Jones Farm campus.
While its chips dominate in personal computers and servers, Intel has been playing catch up in mobile devices, with the company currently having little exposure to smartphones. Here, Intel wireless executive Aicha Evans, center, helps show off Intel's wireless labs inside Jones Farm.
A clean room -- a strictly controlled manufacturing space where chips are made -- requires all workers wear cloth suits, to reduce the amount of particles in the air. Any speck of dust could damage the sensitive work of making chips.
Mathews walks me through the process of putting on the gloves, hood, face mask, boots and suit needed to visit the clean room. The space is filled with yellow light, to protect a lithography chemical used in the machines.
To keep dust and other particles out of the air, GlobalFoundries clean-room workers can only wear odorless deodorant. Makeup and perfumes are prohibited, and workers need to wait two hours after smoking before they can re-enter the facility.
GlobalFoundries' factory works all day, 365 days a year, spitting out about 60,000 chip wafers a month. Here are Brian Rickert, a design engineer, left, and Ed Haldeman, a project manager, who help show me around.
