Abstract: PROBLEM TO BE SOLVED: To form the contact hole having the specified shape by improving the selecting ratio of an insulating film for a photoresist film. SOLUTION: A wafer W is mounted on a lower electrode 106 arranged in a processing chamber 102 of an etching device 100. At the same time, the gas containing C4F8 is introduced into the processing chamber 102. From a plasma generating electrode 120, the electric power of 27 MHz is applied to an upper electrode 114 by a controller 112. At the same time, the electric power of 800 kHz is intermittently applied to the lower electrode 106 from a bias electric power supply 108. When the bias electric power is ON, an insulating film 202 comprising SiO2 of the wafer W is etched. When the power is OFF, a polymer (protecting film) is formed on a photoresist film 206.

Abstract: PROBLEM TO BE SOLVED: To perform a quick seek control by controlling the rotation of a coarse adjusting arm in accordance with the change of the angle formed by the polarization direction of a laser luminous flux by the rotation of the coarse adjusting arm and a track groove at the time of executing a fine adjusting tracking. SOLUTION: A voltage value Vref corresonding to the track position of the moving destination of a rotating arm and the detection signal λES of the output of a detecting circuit 134 are respectively inputted to the noninverted input terminal and the inverted input terminal of a differential amplifier 131 and the difference between them is multiplied by K in an amplifier 132 to be inputted to an actuator driver 133. Then, the difference between them is made so as to become zero by moving the rotating arm while driving a voice coil motor 4 according to this input signal. Here, the detection signal λES is outputted by detecting a return luminous flux from an optical disk with detecting sensors fixed to the rotating arm by the movement of the rotating arm.  Thus, the quick seeking operation is made possible by estimating the directional angle being on the detecting sensors of a diffracted light from track groove with the signal intensity of the detection signal λES and making it zero in this manner.
