Silicon products


Outline   Both “Cross-edge” microprocessing technology and quality assurance system make it possible to realize the highly-reliable silicon products. We continue to supply silicon parts which can meet the technological innovation our customers are handling.


Major advantages
By adopting ultrapure silicon materials (monocrystal/polycrystal), our products can minimize the risk of contamination and maintain your high-quality processes.
As our products have the same characteristics (thermal conductivity, specific heat, coefficient of thermal expansion) as silicon wafer, damage to your product is suppressed much lower than any other material, leading to the improvement in the yield and productivity of your process.
Excellent thermal conductivity realizes the uniform distribution of film and its stability.
Outstanding heat-resistance and corrosion-resistance make it possible to enhance the durability in high temperature process.
High precision processing with complicated shapes can meet various customers' needs.
Ultrapure silicon products can enhance reliability of product without delamination of the coating which may cause contamination.

Samples of processing silicon/ceramics products

We apply our high-precision microprocessing technology to a variety of materials such as silicon, Al2O3, AlN, sapphire, etc. Some of the examples are dicing into bars of 100 &mu m-wide with chipping suppressed, and burr-less metalized ceramic dicing.
