Silicon Wafer
MEMS Wafer
Wafer solutions for leading-edge technology development MEMS components are used in a wide variety of systems ranging from low volume sensoric elements in harsh industrial environments to high volume consumer goods. MEMS is forecasted to impact almost every product category bringing together silicon based microelectronics and micromachining technology in the same package or on the same chip.

Wafer solutions for leading-edge technology development MEMS components are used in a wide variety of systems ranging from low volume sensoric elements in harsh industrial environments to high volume consumer goods. MEMS is forecasted to impact almost every product category bringing together silicon based microelectronics and micromachining technology in the same package or on the same chip.
 
MEMS components require superior mechanical properties of the base silicon material. Pluto fulfills these requirements from all part of the electronics industry grounded on more than half a
century’s experience in manufacturing premium quality silicon wafers. The manufacture is based on Float Zone and Czochralski technology, respectively.
 
Pluto has specialised in growing Float Zone crystals with superior control of dopant content and distribution and with very low levels of contaminants. This is especially beneficial for applications requiring very low concentrations of oxygen such as power MEMS components, high efficiency microstructured solar cells and photodiodes as well as RF MEMS devices on high resistivity silicon.
 
To complete the range of MEMS products, Topsil also offers Czochralski wafers. Czochralski wafers are traditionally being used in MEMS applications with focus on the mechanical parameters and not on the bulk properties of the silicon. Most applications require low oxygen content, but a limit of 18 ppma (new ASTM) is sufficient in many cases.
