Test wafers

WHS manufactures high-quality aluminum test wafers designed for a range of cleanroom applications. These wafers, near SEMI-standard, are durable and versatile, making them ideal for operator training, automation setup, target wafer customization, and electrostatic chuck protective covers in wafer process chambers. With precise engineering and carefully selected materials, WHS aluminum test wafers are built to withstand rigorous use, reducing the risk of damage to more sensitive silicon dummy wafers. 

Made from aluminum alloy 5754-H22, these test wafers are heat-treated for high resistance to deformation and warping, with a surface roughness of 1.6μm Ra. WHS can supply aluminum test wafers to suit your specific needs, providing reliable performance in cleanroom environments.
