Disclosed is a method of producing a polyester fire-retardant core matrix for a prefabricated panel. The method includes adding a fire-retardant agent to a polyester floss to allow the fire-retardant agent to permeate into the polyester floss, rolling the polyester floss, drenched by the fire-retardant agent, using a roller to promote permeation of the fire-retardant agent into the polyester floss, drawing the excess fire-retardant agent from the polyester floss using a perforated roller, of which an air suction force is easily controlled, drying the semi-dried polyester floss using a microwave generating unit, and foaming the dried polyester floss using a heater. The polyester fire-retardant core matrix has advantages of excellent fire-retardancy, high strength, and low absorptivity.

Provided is a vascular stent used in percutaneous coronary intervention (PCI) which is specially designed for multiple drug loading and improved drug elution, including: a plurality of ring structures extending in the longitudinal direction of the vascular stent, including a plurality of struts disposed in a zigzag formation and connected to each other to form a cylindrical loop; and a plurality of link structures disposed between the ring structures and connecting the ring structures in the longitudinal direction of the vascular stent, wherein each of the struts in a ring structure is connected to adjacent struts in the same ring structure through one of a plurality of linking ends, a slot loaded with drugs is formed in the strut in the longitudinal direction of the strut, and a multi-layer structure comprising a plurality of layers of drugs is loaded in the slot. The vascular stent effectively inhibits restenosis by loading a large amount of a drug or various types of drugs in multiple layers in slots of struts in the vascular stent and controlling elution of the drugs, and can be easily installed in a serpentine coronary artery with excellent flexibility. In addition, the link structure of the vascular stent is disposed in a symmetric formation, and thus, side branch accessibility is excellent and an additional coronary intervention can be performed easily in a branched artery.

A first insulating film is formed on a substrate or a lower metal wiring, and a first metal layer is formed on the first insulating film. A second insulating film and a third insulating film are formed on the first insulating film and the first metal layer, and the third insulating film and the second insulating film are selectively slope-etched by using a first photosensitive film mask to form a sloped pad opening portion. A barrier metal layer and a pad metal layer are formed over the substrate, and the pad metal layer and the barrier metal layer are selectively etched by using a second photosensitive film mask to form a bonding pad. A fourth insulating film is formed over the substrate, and the fourth insulating film is selectively etched by using a third photosensitive film mask to expose a part of the bonding pad.

A method for fabricating a semiconductor device includes forming a first insulating pattern, a first conductive pattern, and a second conductive pattern on a semiconductor substrate; forming a spacer on sidewalls of the first insulating pattern, the first conductive pattern, and the second conductive pattern; forming a second insulating pattern over the substrate; forming a first salicide on an exposed portion of the substrate and a second salicide on an entire upper surface of the second conductive pattern; depositing a third insulating layer over the substrate, and etching selectively the third insulating layer to forming first and second contact holes exposing the first and second salicides. The method provides processing margin and prevents excessive etching of a conductive layer under the salicide, even if misalignment of an overlying contact hole happens.

A slit coater with a standby unit for a nozzle and a coating method using the same prevents environmental pollution by solvent steam and simultaneously maintains the slit nozzle in an optimum state. When in standby and not performing a coating application, the slit nozzle is kept in a standby unit having a solvent atmosphere therein. The slit coater includes: a table on which an object to be processed is positioned; a slit nozzle for applying a coating solution onto a surface of the object; and a standby unit into which the slit nozzle is loaded when on standby, and having a shutter at the opening thereof to maintain an inner space in a substantially hermetically sealed solvent atmosphere. The atmosphere in the standby unit is configured to prevent hardening of the coating solution in the slit nozzle and thereby maintain the slit nozzle in the optimum state for providing coating applications.
