Abstract: Provided is a semiconductor device and a manufacturing method thereof. The method includes the steps of: forming a thin film transistor including a substrate having a semiconductor layer and silicon, a gate insulation layer formed on the semiconductor layer, a gate electrode formed on the gate insulation layer, and source and drain regions formed in the semiconductor layer; forming a first metal layer on the substrate having the semiconductor layer and the gate electrode; forming a second metal layer on the first metal layer; forming a third metal layer on the second metal layer; forming a nitride layer on the third metal layer; and annealing the substrate having the nitride layer, and forming a silicide layer on the gate electrode and the source and drain regions.

Abstract: Disclosed is a built-in refrigerator provided in a sink and effectively discharging heat from a condenser and a compressor. The built-in refrigerator includes a cabinet provided in the sink and a component chamber at a rear bottom thereof and a dust guard provided at a front bottom of the cabinet; a compressor provided in the component chamber; a condenser provided under a bottom surface of the cabinet; a ventilating passage communicating the component chamber with a bottom of the cabinet and outside of the dust guard for discharging heat generated from the condenser and the compressor to outside; and a cooling fan provided in the component chamber for cooling the compressor and the condenser.
