Silicon (Si) is a semiconductor-grade material widely used in electronics, photonics, and MEMS manufacturing due to its controlled electrical properties, high purity, and thermal stability. We offer high-precision CNC machining of monocrystalline and polycrystalline silicon components, including wafers, substrates, and structural parts for cleanroom and high-vacuum environments.
Silicon is a crystalline elemental material with a diamond-cubic structure. It is the foundation of the semiconductor industry, valued for its predictable electronic behavior, low thermal expansion, and compatibility with microfabrication. In mechanical form, silicon also serves in precision optics, sensors, and thermal isolation components.
We offer CNC machining for high-purity sintered Silicon (Si).
