High Quality Glass Wafers

We can offer a wide range of glass wafers that meet your needs. Size and thickness, as well as material type, such as borosilicate, optical glasses or alkali-free glasses can be selected. We are also able to offer custom processing solutions to meet your project’s specific needs.

Dummy glass wafers are glass wafers for experimentation and inspection that are different from those used as components. It is used to improve stability of manufacturing equipment and processes, and is also used for process evaluation. Furthermore, it is often used for experimenting or testing of new processes.

Application

Testing settings for semiconductor processes, structural support for Si polishing

SEMI Standards Compliant

Standard Production Spec

Glass substrates are used in many experimental tests and product manufacturing processes. In general, test-only dummy glass wafers are used for test operation, but quality may vary.
We can provide dummy glass wafers with strict size and thickness requirements based on the SEMI standards. It also applicable to a wide range of user needs, such as laser engraving and coating.

Precision Processing

Precision dimensions (size, thickness) unstructured wafers are available.

Laser Marking

User specification such as laser engraving can be requested.

SEMI SPEC

We support a variety of wafer specifications that comply with the SEMI standards.

Wide range of applications

With over 40 years of accumulated glass processing technology, we realize designs that were impossible with conventional processes.
