摘要： A semiconductor device protecting the ends of a gate line and a method of forming the same are disclosed. The semiconductor device includes a semiconductor substrate, a gate line crossing over the semiconductor substrate, and a protecting pattern covering ends of the gate line. According to the method, a gate line is formed at a semiconductor substrate. A spacer is formed to cover sidewalls of the gate line. A protecting pattern is formed to cover the ends of the gate line. The protecting pattern may be formed of silicon nitride or silicon oxide. Since the protecting pattern protects ends of a gate line, it is possible to prevent gate electrodes from being damaged by a cleaning solution such as SC1 in a subsequent process.

摘要： The present disclosure relates to an acid catalyst composition for producing 5-chloromethyl-2-furfural from galactan derived from seaweed and a method for producing 5-chloromethyl-2-furfural from galactan derived from seaweed on a two component phase using the acid catalyst, the acid catalyst composition for producing 5-chloromethyl-2-furfural from galactan derived from seaweed including organic solvent and dilute hydrochloric acid, a concentration of the dilute hydrochloric acid being 4N to 8N (normal).According to the present disclosure, there is an advantage of converting 5-chloromethyl-2-furfural from galactan derived from seaweed by means of a single process by mixing dilute hydrochloric acid and organic solvent by an optimal ratio, unlike conventional methods for producing 5-chloromethyl-2-furfural that had to go through a multi-phase process of preconditioning and saccharification.
