Abstract:
Disclosed herein is a patterning mold to form a micropattern on a substrate or glass. The disclosed patterning mold includes a body having a patterning part formed at one end of the body. The patterning part may be configured to contact a surface of the substrate, to form a channel. In example embodiments, an ink supply passage communicating with the channel may be formed in the patterning mold, to supply an ink to the channel. In example embodiments, a fixing member is coupled to an exterior of the transfer body, to prevent or reduce deformation of the exterior of the transfer body.
Abstract:
According to example embodiments, a printing apparatus includes a wafer delivery unit configured to move and support a wafer, an optical microscope configured to inspect the wafer, a pattern transfer unit configured to display a position of a defect on the wafer detected using the optical microscope.
Abstract:
An ink composition for flexo printing contains a dye type colorant in order to precisely print. The ink composition for flexo printing includes about 1 to 40 wt. % of a colorant, about 5 to 40 wt. % of a binder, about 20 to 95 wt. % of a solvent and a remainder of an additive, wherein the wt. % of the colorant, the binder, the solvent and the additive is based on a total weight of the ink composition.
