Substrate cleaning device and substrate cleaning method

A substrate cleaning device and a substrate cleaning method reduces liquid drops remaining on a substrate to prevent the irregular heating of the substrate by a heating process due to liquid drops or water marks remaining on the substrate. A cleaning liquid is poured through a cleaning liquid pouring nozzle onto the surface of a substrate such that a region onto which the cleaning liquid is poured moves from a central part toward the circumference of the substrate. A gas is jetted radially outward at a region on the surface of the substrate behind a region onto which the cleaning liquid is poured with respect to the rotating direction of the substrate. The gas forces a liquid film of the cleaning liquid flowing on the surface of the substrate to flow in a circumferential direction and a radially outward direction. The cleaning liquid poured out onto the surface of the substrate through the cleaning liquid pouring nozzle is restrained from flowing by a liquid damming member held at a height equal to or lower than that of the nozzle exit of the cleaning liquid pouring nozzle to collect a mass of the cleaning liquid. A high centrifugal force acts on the mass of the cleaning liquid to force the mass of the cleaning liquid to flow outward even if the substrate is rotated at a low rotating speed.

Method of improving channel switching speed in digital television receiver and the digital television receiver

Provided is a method of improving a channel switching speed in a digital television (TV) receiver. The method includes: generating transport stream packets by channel tuning and demodulating a broadcasting signal of a channel selected by the channel change instruction;outputting the transport stream packets before completion of tuning and demodulating of the broadcast signal; andgenerating video and / or audio data by demultiplexing and decoding the outputted transport stream packets. In addition, a digital TV receiver applying the improvement of the channel switching speed is provided. The digital TV receiver includes a tuning and demodulating unit generating transport stream packets by tuning and demodulating a broadcasting signal of a broadcasting channel selected by a channel change instruction and outputting the transport stream packets before completion of the tuning and demodulation of the transport stream packets. The digital TV receiver starts screen mute in response to the channel change instruction and terminates the screen mute when a normal image display is possible by using the transport stream packets output from the tuning and demodulating unit. Therefore, the channel switching speed increases as compared with a case where the improvement of the channel switching speed is attempted by using the transport stream packets.
