Latest Patents

Tashiro holds a patent for a negative photoresist stripping liquid composition. This innovative composition comprises from 30 to 75% by weight of dimethyl sulfoxide, from 20 to 65% by weight of 1,3-dimethyl-2-imidazolidinone, from 0.1 to 5% by weight of a tetraalkylammonium hydroxide, and from 0.5 to 15% by weight of water. The composition demonstrates superior stripping performance, particularly against alkali-developable photoresists that can form films of at least 20 µm in thickness. Additionally, it remains stable and does not freeze when stored outdoors in winter conditions. This composition is particularly useful for stripping negative photoresists used in bump formation and for fabricating circuit substrates. Tashiro has 1 patent to his name.
