Method for testing for blind hole formed in wafer layer
Apr 19 , 2021
A new method for detecting blind holes in the contact layer of a multi-chip semiconductor test wafer makes use of the fact that if the hole is not a blind hole, a subsequent etch step extends the hole a predetermined distance into the layer immediately underlying the contact layer. After a predetermined number of holes have been etched through the contact layer and for a predetermined distance int...

Why choose UV laser cutting machine for wafer cutting
May 17 , 2021
Why choose UV laser cutting machine for wafer cutting Most semiconductor materials have a good absorption of light in the ultraviolet band. Take the absorption of monocrystalline silicon in different wavelength bands as an example. When laser processing in the ultraviolet band is used to process semiconductor materials, due to the narrow focus spot of ultraviolet light, the photon energy is ...
