Abstract: A method for manufacturing a TFT is provided to prevent the contamination of a metal electrode and to lessen the degradation of step coverage due to a stacked portion under a gate insulating layer. A silicon channel material layer and a silicon ohmic material layer are sequentially formed on a substrate(20). Source and drain ohmic layers(23s,23d) for contacting a silicon channel and both end portions of the silicon channel are formed on the resultant structure by patterning selectively the channel material layer and the ohmic material layer. A gate insulating layer(24) is formed on the resultant structure to cover the source and drain ohmic layers. A gate(25) is formed on the gate insulating layer corresponding to the channel. An interlayer dielectric(26) for covering the gate is formed on the gate insulating layer. A contact hole(H) through the interlayer dielectric and the gate insulating layer is formed on the source and drain ohmic layers, respectively. Source and drain electrodes(27s,27d) for contacting the source and drain ohmic layers through the contact hole is formed on the interlayer dielectric. A passivation layer is then formed on the resultant structure to cover the source and drain electrodes.

Abstract: A recording method for an optical recording and reproducing apparatus is provided to prevent a recording error through a pretreatment such as the replacement of an optical disc and prevent the loss of information by displaying recording environment before the start of record and predicting a recording successful rate. If an optical disc is loaded(S101), a kind of the optical disc is judged(S103). When the loaded optical disc is a recordable disc, an initialization process for setting RF(Radio Frequency) power and servo timing is performed(S105). The optical disc is divided into a plurality of areas, and a characteristic value including a focus offset, the optimum tilt determination value, and an RF reflective signal level is confirmed according to the respective areas(S107). An OPC(Optimum Power Control) process for selecting recording power suitable for the optical disc is performed in inner circumference and outer circumference, and record is performed for a specific sector(S109). A grade of recording environment is determined according to the deviation of the area-classified characteristic values of the optical disc, an OPC jitter value, and a bit error rate(S111). The determined recording environment grade is displayed to predict a recording successful rate(S113). Recording start power is set up from the recording power selected in the OPC process in consideration of a current recording speed, and data to be recorded are recorded in the optical disc according to a file structure by using the set recording start power(S115-S123).

An equipment for purifying water of a freshwater lake or river comprises: a floating body(10) floating on the freshwater lake; a pump installed at one side of the floating body to pump up water around the bottom of the freshwater lake; sedimentation separating tanks(30) for settling sludge contained in an influent supplied from the pump and performing an anaerobic digestion actively; batch type treating tanks(50) for repeatedly aerating and settling an influent that has been treated in the sedimentation separating tanks and the concrete filter part; a final sedimentation tank(60) which settles an influent that has been treated in the batch type treating tanks, and has an air lift(61) for returning excess sludge and nitrifying bacteria to the sedimentation separating tanks or the batch type treating tanks; an aeration type discharge tank(70) for eradicating Escherichia coli in an influent that has been treated in the final sedimentation tank and guiding stable discharge of treated water; and a concrete filter part(40) installed on upper parts of the respective tanks to contact soil strains and plant roots with treated water that has been treated in the respective tanks.

Abstract: An apparatus and a method for performing a scan function in a car audio system are provided to allow a user to accurately recognize the existence of an error track on a compact disk. An apparatus for performing a scan function in a car audio system includes a compact disk scanning unit(170), an output unit, and a control unit(100). The compact disk scanning unit performs a compact disk scan function under predetermined control. The output unit outputs information indicating detection of an error track during compact disk scanning. The control unit controls the compact disk scanning unit to start a compact disk scan function upon detection of a compact disk scan request, and the output unit to output information indicating the detection of an error track, and ejects the compact disk upon detection of an error track during compact disk scanning.
