Latest Patents

Yang holds a patent for a "Vitreous carbon mask substrate for X-ray lithography." This invention focuses on utilizing vitreous carbon as a substrate material for creating masks used in X-ray lithography. The new substrate allows for a reduced thickness of the mask absorber, which in turn improves mask accuracy. An alternative embodiment of this invention involves using vitreous carbon as a LIGA substrate, where the VC wafer blank is etched in a reactive ion plasma, followed by bonding an X-ray resist. This surface treatment ensures good adhesion of the X-ray photoresist and facilitates the nucleation and adhesion of electrodeposited metal for LIGA mold-making. Additionally, the VC substrate effectively minimizes secondary radiation effects that can lead to delamination of the X-ray resist from the substrate.
