    摘要: Provided is an etching composition for electively removing silicon dioxide at a high etch rate, more particularly, a composition for wet etching of silicon dioxide, including 1 to 40 wt % of hydrogen fluoride (HF); 5 to 40 wt % of ammonium hydrogen fluoride (NH4HF2); and water, and further including a surfactant to improve selectivity of the silicon dioxide and a silicon nitride film. Since the composition for wet etching of silicon dioxide has the high etch selectivity of the silicon dioxide to the silicon nitride film, it is useful for selectively removing silicon dioxide.

    摘要: An ink composition for roll printing is provided. The ink composition uses a solvent having an evaporation rate (Vt) of at least 0.09 mg/cm2-min and an absorption rate (St) into a blanket of less than 3.5 mg/cm2-min. The use of the highly volatile solvent can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent can be minimized.
