Laser Marking Glass

Laser Marking

Coresix has multiple UV and CO2 laser systems for the application of unique serialization to glass wafers. Our systems accommodate SEMI standards and custom parameters to precise location. Once the laser mark is applied, the wafer is re-cleaned and inspected before final packaging. Wafer ID’s can be applied to the label and data provided to each part.

Inspecting Glass


A surface imperfection not visible to the naked eye can become a glaring defect when magnified in the end product. A particle of glass, a finger print, a water spot may go unnoticed until enhanced by the application of optical films.

Chemical Strengthening Glass Process

Chemical Strengthening

Coresix performs chemical strengthening by inducing an exchange between the larger Potassium ions of the chemical bath and the smaller Sodium ions of the glass. The resulting compacted surface stress greatly increases the strength of the glass without optical distortion.
