From harnessing the first electron beams…

The roots of a Temescal system run deep, back to labs in Berkeley in the 1950s where we pioneered the first electron beam evaporation components and began patenting the first e-gun designs. Over the years, electron beam evaporation has become a well-established method for thin film coating, so well established that some might believe that a system is simply the sum of a vacuum chamber, an electron beam gun, and a high-voltage power supply.

…to volume Compound Semiconductor Metalization…

With our long history in designing and building electron beam evaporation systems, we know that a system is more than an assembly of parts. A precision tool for high-volume uniform coating is a symphony of specialized components, operating in precise relationships with careful optimizations that harmonize the system with multi-step coatings and the heart of the entire process, the flux cloud.

…we build highly optimized production tools…

From our most basic systems designed for R&D or pilot production to our top-of-the-line lift-off coaters, every Temescal system is designed for precision, efficiency and throughput. It’s one reason why the world’s leading compound semiconductor manufacturers depend upon Temescal systems, batch after batch, day after day.

…we engineer process material uniformity…

For us, the vapor cloud is the heart of every electron beam evaporation system. Each material evaporated by an electron beam produces a unique cloud, a repeatable flux distribution characteristic of radiation from the point source. Coating uniformity depends on the relationship between the wafer surface and the cloud. But the flux cloud isn’t static; it’s dynamically shaped by everything from deposition material, power, beam spot focus, crucible size—even factors like whether you’re using a crucible liner. We engineer Temescal systems to manage these variations, to harmonize with the cloud and deliver unparalleled uniformity.

…we are experts in the Science of the Vapor Cloud.

For over a decade, Temescal has been dedicated to mapping and better understanding the dynamics of the flux cloud. Through extensive testing and research, we have collected hundreds of vapor cloud maps and used these maps to advance and automate the process of Lift-off uniformity mask design. Now, Temescal systems incorporate this expertise in our Auratus deposition enhancement methodology, ensuring that your process is always harmonized to the cloud.

Temescal operates out of our facilities in Livermore, California.
