Foundry is a booming business that manufactures parts for hundreds of industries. Foundries manufacture semiconductor devices for a variety of end markets. Given the breadth of devices they manufacture, foundries require extensive materials. VEM supplies foundries with sputtering targets and evaporation materials ranging from Aluminum to Zirconium and just about everything in between.

Data Storage

The demand for data storage seems endless. Big data is driving the requirement for big data storage devices. New materials continue to enable innovative solutions to today's data storage challenges. VEM is working with the major data storage suppliers to provide these solutions.


Memory and Logic devices constitute the greatest volume of semiconductor devices in the industry. Every year devices require more and more memory and VEM works with producers to keep up with the demand. Memory devices include DRAM, SRAM, and non-volatile memory devices or flash memory devices. Logic devices include microprocessors, micro-controllers, ASIC's, and PLD's. For decades, leading logic and memory companies have been innovating with new materials to get to the next generation of devices. VEM has been working with many of the largest device suppliers throughout that time.

RF Wireless Communications

The rapid growth of smartphones has driven a demand for high speed communications devices. The explosive growth of this industry requires significant high quality materials to keep up with the constant new innovations. These materials must be of high purity and low resistivity to provide maximum performance. We supply ultra high purity gold Evaporation Materials in any shape or size you may need at fair prices. VEM is working with all of the major RF Wireless device manufacturers to find solutions to their next generation devices.
