Abstract: Disclosed is a cutting oil composition, which is vastly superior in view of layer separation, dispersibility, viscosity, ingot-cleaning time after sawing, and wafer warpage after sawing, compared to conventional cutting oil compositions, and which includes mineral oil that is highly hydrogenated, as represented by Chemical Formulas 1 to 3, bentonite clay as a thickener, and glycerol trioleate as a dispersant. A cutting method using the cutting oil composition is also provided.

Abstract: The present invention relates to an anti-reflective coating solution composition and an anti-reflective coating film using the same. More particularly, an anti-reflective coating solution composition is provided, which has a low refractive index to thus improve transmittance and can also increase abrasion resistance to thus maintain an anti-reflective effect for a long period of time, whereby an anti-reflective coating film for improving solar cell module efficiency can be formed, and thus can be applied not only to a solar cell module glass but also to glass in a variety of fields.

Abstract: Disclosed are a cleaning composition for photolithography and a method of forming a photoresist pattern using the same. The cleaning composition, necessary for forming a photoresist pattern having a high aspect ratio, includes water and a compound represented by Chemical Formula 1 below: wherein R is H or OH, x is an integer selected from 1 to 100, y is an integer selected from 0 to 100, and z is an integer selected from 0 to 100. This cleaning composition is useful for forming a pattern using any of a variety of light sources, and also, even when it is difficult to form a fine pattern as desired using a photoresist alone, a fine pattern can be realized at a desired level of fineness and production costs can be reduced.
