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.
Power devices are semiconductor devices used as switches or rectifiers in power electronics. They include power diodes, MOSFETs and IGBTs. VEM has been working with suppliers of all of these devices to provide innovative solutions to their materials needs.
Evaporation Materials: VEM provides evaporation materials ranging from pure elements to compounds and alloys. We provide our metals in many shapes and sizes from small granules and wire to large pellets to suit any needs. VEM will collaborate with you to provide you with materials to your specifications.
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.
Light-Emitting Diodes, or LED's are devices that emit infrared or visible light when charged with an electric current. LED's are rapidly being adopted as an efficient and low energy solution in a broad range of applications from indicator lamps to general lighting. LED's are fabricated on compound semiconductor substrates such as GaAs and GaN. VEM is working with many of the largest suppliers of LED devices. We're helping them develop new materials and new solutions to their R&D and production challenges.
