Abstract: Provided are a silicon nitride film etching composition, a method of etching a silicon nitride film using the same, and a manufacturing method of a semiconductor device. Specifically, a silicon nitride film may be stably etched with a high selection ratio relative to a silicon oxide film, and when the composition is applied to an etching process at a high temperature and a semiconductor manufacturing process, not only no precipitate occurs but also anomalous growth in which the thickness of the silicon oxide film is rather increased does not occur, thereby minimizing defects and reliability reduction.

Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

Abstract: There is provided a drill bit comprising a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body, having a channel coupled to the receptor portion formed therein, and having an opening formed in one end thereof and connected to the channel; and a cutting portion provided at a periphery of the opening of the drilling portion for drilling a workpiece, wherein the channel of the drilling portion has a small diameter in order that the cutting oil is not discharged outside of the channel by external pressure or gravitational force, and the channel of the drilling portion has a structure in which capillary action occurs due to cut chips flowing through the channel during drilling of the workpiece so that the cutting oil may be discharged by the capillary action.

Abstract: The present disclosure provides a brazing bond type diamond tool having excellent cuttability and a method of manufacturing the same. The diamond tool includes a shank having a body and a tip portion formed along an edge of the body, and a brazing bond layer formed on the tip portion of the shank to secure diamond particles with a brazing bond. The tip portion is thinner than the body and is integrally formed with the body.

Abstract: There is provided a drill bit capable of performing a continuous drilling operation on a high-strength workpiece such as a tempered tile and the like. The drill bit comprises a bit body having a receptor portion formed therein, the receptor portion being filled with a cutting oil; a drilling portion extended from one end of the bit body and coupled to the receptor portion of the bit body to form a channel in which a capillary phenomenon occurs, and having an opening formed in one end thereof; and a cutting portion provided in the opening of the drilling portion to drill a workpiece. The drill bit thus configured may be useful to enable a continuous drilling operation on the high-strength workpiece, to enable the refilling of a cutting oil used to cool the high-strength workpiece, to shorten a time for the drilling operation on the high-strength workpiece, and to drill the high-strength work-piece to the maximum extent using the minimum number of drill bits.
