Semiconductor Surface Detector Systems Optical Testing Equipment
40x
Applications
For the process control and yield management of blank mask in the
fields of semiconductor display and
integrated circuit chip manufacturing, we use high throughput optical testing
technologies to make fast and
accurate automatic detection for the surface defects of blank mask. According to
professional user needs,
we have developed series of high throughput MASK inspection machines with reliable quality and
high cost
performance ratio, to help glass substrate, mask and panel manufacturers to identify and monitor the mask
defects, reduce the risk of yield and improve their independent ability of R&D for core technologies.
Working Principle
With regards to level and type of surface defect, 4x telecentric
lens, specific angle ring light and coaxial light
source are selected as the visual approach. When the device is running,
the sample moves along the X
direction and the vision module carries out defect detection along the Y direction.
