摘要： An image forming apparatus having an automatic document feeding unit so as to successively read documents is disclosed. The image forming apparatus includes an image forming unit to form an image on a printing medium, an image reading unit pivotally coupled to an upper portion of the image forming unit to expose and shield a top of the image forming unit, an automatic document feeding unit pivotally coupled to an upper portion of the image reading unit to expose and shield a top of the image reading unit, and a locking device to selectively expose any one of the top of the image forming unit and the top of the image reading unit. Since the locking device prevents the top of the image forming unit and the top of the image reading unit from being simultaneously exposed, the automatic document feeding unit can be prevented from being damaged due to the simultaneous exposure of the top of the image forming unit and the top of the image reading unit.

摘要： A metal thin film with an ohmic contact for light emit diodes and a method of producing such a film are disclosed. The metal thin film has a p-type gallium nitride (GaN) semiconductor layer. Nickel (Ni), platinum (Pt) and gold (Au) layers are deposited on the GaN semiconductor layer in a way such that the gold layer forms a top layer, with either one of the platinum and nickel layers being selectively used as an inter-diffusion barrier between metal layers. The inter-diffusion barrier may be formed by depositing platinum between the nickel and gold layers, thus forming an Ni/Pt/Au metal thin film, or formed by depositing nickel between the platinum and gold layers, thus forming an Pt/Ni/Au metal thin film. In the method, a GaN semiconductor is washed so as to be free from carbide and oxide layers. The Ni, Pt and Au layers are formed on the GaN semiconductor layer through a vacuum deposition process at 5×10−5-2×10−1 torr. The GaN semiconductor, having the metal thin film, is heat treated for 30 seconds-3 hours and at 250-1,000° C., and under nitrogen or argon ambient.
