Product description

Perfect for microfluidics applications. For microelectronics or MEMS applications, please contact us for detailed specs.

 

Microelectronics’ product line includes both single side polished (SSP) and double side polished (DSP) wafer substrates. Double side polished wafers are typically required in semiconductor, MEMS, and other applications where wafers with tightly controlled flatness characteristics are required. They are also needed for double side patterning and device manufacturing projects.

Large stock of double side polished wafers in all wafer diameters ranging from 100mm to 300mm.  If your specification is not available in our inventory, we have established long term relationships with numerous vendors that are capable of custom manufacturing wafers to fit any unique specifications. Double side polished wafers are available in silicon, glass and other materials commonly used in the semiconductor industry.

Customized dicing and polishing is also avaible according to your requirements. Please feel free to contact us.
