Dummy Wafer

Dummy Wafer
Product Introduction:
Dummy wafer is a fundamental, low-cost tool used to maintain, calibrate, and stabilize multi-million-dollar semiconductor manufacturing equipment. They ensure that by the time a high-value product wafer enters the tool, the environment is perfectly controlled and predictable, maximizing yield and quality. Without dummy wafers, the consistent production of modern chips would be impossible.

Bare Wafer 1

Dummy wafers are widely used in semiconductor manufacturing as a cost-effective solution for equipment calibration, process stabilization, and routine testing. Unlike product wafers, dummy wafers do not carry active circuits, but they play a critical role in ensuring that production tools run smoothly before high-value silicon wafers are processed.

Our silicon dummy wafers are available in 6-inch, 8-inch, and 12-inch sizes, with multiple options for dopants (P/Boron or N/Ph), thickness, flats or notches, and surface finishes (as-cut, lapped, etched, SSP/DSP). These specifications make them suitable for a wide range of applications, from tool qualification to process development and equipment monitoring.

By using dummy wafers, manufacturers can reduce costs, improve wafer yield, and maintain consistent quality in chip production. They are a practical choice for fabs, research labs, and semiconductor equipment maintenance.
