Latest Patents
Shimada's latest patents focus on innovative solutions for creating conductive and insulating layers on glass substrates. His inventions aim to resolve problems related to solvent handling and wastewater treatment during the photolithography process. One of his key patents describes a method for forming a conductive layer or an insulating layer using a photosensitive slurry solution. This solution is prepared by mixing low-melting glass powder with conductive or insulating powder into a PVA-based, water-soluble photosensitive solution. The careful regulation of the B.sub.2 O.sub.3 component in the low-melting glass powder to not more than 6% by weight allows for effective coating without gelation of PVA. This method presents a more environmentally friendly alternative to conventional solvent-based photolithography.
