摘要： A method for manufacturing a semiconductor device or a semiconductor wafer is provided, in which a removal of slurry that is adherently remained on the back surface of the semiconductor wafer can be ensured without a need for employing an increased dimension of apparatus. An edge portion of a semiconductor wafer is polished while a back surface of the semiconductor wafer is chucked to a chucking unit of a first polishing unit, and then, the polished semiconductor wafer is dechucked from the chucking unit of the first polishing unit. Next, a predetermined gap is formed in a location above the chucking unit of the second polishing unit, and the semiconductor wafer is disposed therein. Water is discharged form the chucking unit of the second polishing unit to clean the back surface of the semiconductor wafer W. Thereafter, the back surface of the semiconductor wafer is chucked to the chucking unit of the second polishing unit, and then the semiconductor wafer is polished.

摘要： Optical amplifier which can eliminate the need for an optical detection section before an external attenuating medium, can prevent SN degradation, and can reduce power required for pumping light. An attenuation amount detection section detects an amount of signal light attenuation caused by a variable optical attenuator and the external attenuating medium connected in series, by means of a front optical detection section provided before the variable optical attenuator and the external attenuating medium and a back optical detection section provided thereafter. An attenuation amount control section controls the variable optical attenuator such that the amount of signal light attenuation detected by the attenuation amount detection section is kept constant. A connection detection section detects a connection or disconnection of the external attenuating medium in accordance with the amount of signal light attenuation obtained when the amount of attenuation caused by the variable optical attenuator is minimized.

The wafer block is bonded to a dummy block on a support plate. Next, a processing step and a cutting step are repeated. The processing step is to perform specific processing on the medium facing surfaces of a row of slider sections in the medium facing surface of the wafer block bonded to the support plate. The cutting step is to cut the wafer block together with the support plate such that the row of slider sections whose medium facing surfaces have received the specific processing are separated from the wafer block to be the bar.

摘要： A thin-film magnetic head comprises a top pole layer incorporating a throat height defining layer and a yoke portion layer. The throat height defining layer is formed as follows. A magnetic layer to be a track width defining portion is formed on a recording gap layer. Next, the magnetic layer is selectively etched through the use of a mask so as to form an end portion of the magnetic layer for defining the throat height. Next, a nonmagnetic layer is formed to fill the etched portion of the magnetic layer while the mask is left unremoved. Next, the yoke portion layer is formed. Using the track width defining portion as a mask, the magnetic layer, the recording gap layer and a portion of the bottom pole layer are etched.
