Imec cleanroom

Leuven, Belgium

The chip design center Imec is located in the medieval city of Leuven, Belgium. The historic buildings are a strong contrast to Imec's high-tech mission, but they come together with common links to the city's university, founded in 1425.

Imec built a new $1.1 billion clean room, a mammoth block of a building that will be used to design the computer chips that will arrive in 2020 and beyond.

For now, Imec's new clean room is nearly empty. This will change as new chipmaking equipment is installed so the chip industry can figure out what will work best to build future chips. The clean room is so named because it's kept free of dust and other contaminants that can spoil the super-small features of computer chips.

The current Imec clean room is packed with chipmaking equipment. Processors are made as circular disks of silicon crystals are shuttled from one machine to another. The machines lay down precise patterns of circuitry that form tiny on-off switches called transistors.

The new Imec clean room is a hulking presence, but its exterior is reflective to help the building seem more like whatever mixture of clouds or blue sky prevails over the Belgian city of Leuven.

Imec is working on contact lenses that, after detecting whether a person is trying to read something up close or look at something farther away, autofocus accordingly. It's like bifocal glasses without the glasses.

Belgium is partial to cycling with bike paths all over that are widely used even in bad weather. This one leads from the center of Leuven to Imec to the south of the city center.

Imec is branching out beyond helping chip industry companies to others wrestling to rebuild their businesses around computer technology. One example: this chip that can sort blood cells down different guides depending on whether their shape indicates the cell is cancerous. Imec's technology currently checks 4,000 cells per second, but researchers want to speed it up.

Andy Lambrechts, an Imec imaging program manager, shows how a hyperspectral image sensor takes 25 photos of the same scene, each photo in a different frequency of light. The technique can be used to spot food that's going bad or help scientists looking at satellite photos figure out exactly what plants are growing where.

Imec is researching hyperspectral image sensors, which capture many different colors of light, unlike human eyes, which see the world in just red, green and blue. Hyperspectral imaging has been a very expensive technology, but building it directly into the chip makes it cheap enough that farmers spraying fertilizer on crops can use computer analysis to instantly figure out exactly how much to use as a tractor traverses the field.

When fruits and vegetables go bad, they can change colors, but it's not always so obvious as in this case. Hyperspectral imaging can spot subtle signs.

A hyperspectral camera reveals much more information about a field than an ordinary camera or human eye can detect.

Imec's new cleanroom is seamlessly attached to the earlier building, but it breaks with the prevailing architectural style.

Imec's new cleanroom will be used to develop chipmaking processes for the whole chip industry. That industry funds Imec's cooperative work. The farther in the future the technology -- and the organization is looking at chips that will arrive in 2024 -- the more cooperative. Nearer-term research tends to be more proprietary and specific to a particular chipmaker like Samsung, Intel or Taiwan Semiconductor Manufacturing Corp.

Imec has developed prototype brain activity monitors that are easier to wear than a bunch of electrodes.

Imec is working on chip technology to make self-driving cars more economical. This chip is for radar that can detect events like another car ahead braking.

Imec is investigating not just traditional silicon solar cells, but also transparent thin-film solar cells that could be built into windows. It's also looking at combining the two to improve how much electrical power a solar panel can generate.

Imec has grown since its founding in a single building in 1984. Now it's got a cluster connected by pathways and rainproof corridors.

Imec Tower is modern but resembles medieval European buildings whose upper stories have more area than the ground floor -- an architectural design decision that made sense when taxes were based only on the ground-floor footprint.
