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.


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.


Photovoltaics are a method of generating electrical power by converting light into electricity. There are a variety of solar cell technologies competing for highest efficiency and lowest cost. Thin film technology is crucial to a solar cell, and VEM has the answers with our high purity Sputtering Targets and Evaporation Materials. The most common technologies are crystalline silicon (c-Si), Cadmium Telluride (CdTe), and Copper Indium Gallium Selenide (CIGS). VEM provides materials for all of these technologies.
