摘要： A photoresist composition includes an alkali-soluble resin, a dissolution inhibitor including a quinone diazide compound, a first additive including a benzenol compound represented by the following Chemical Formula 1, a second additive including an acrylic copolymer represented by the following Chemical Formula 2 and an organic solvent. Accordingly, heat resistance of a photoresist pattern may be improved, and the photoresist pattern may be readily stripped. As a result, crack formation in the photoresist pattern may be reduced and/or prevented.

摘要： The present invention provides a stent that allows a simple surgical operation for affected parts of a lumen in a human body, and particularly reduces a medical side effect by contact or friction between the inside of the lumen and the outside of the stent when the stent is removed from the lumen. The stent includes a cylindrical wire structure having an internal passage and wires that are bent along the internal passage to have peaks and valleys, and a cover film that covers the wire structure. In particular, the cover film covers the wires such that the wires are embedded at the outside of the wire structure and exposed at the inside.
