Abstract: PROBLEM TO BE SOLVED: To improve fine adjustment accuracy and prevent reduction in product quality by stopping the progress of etching individually and efficiently. SOLUTION: This method is used for manufacturing of a plurality of ultrathin piezoelectric resonator original plates simultaneously by using a large-area piezoelectric wafer. A plurality of recessed parts 2 are formed on the surface of a piezoelectric wafer 1 in the prescribed arrangement by etching, and then an ultrathin vibration part 3 is formed on the bottom of the respective recessed parts 2 and the variance of the wall thickness of the respective ultrathin vibration parts 3 formed on the piezoelectric wafer 1 is measured. Furthermore, an etchant 16 is dripped in the respective recessed parts 2 to correct the variance in the wall thickness of the ultrathin vibration parts 3 that is detected in the measurement of wall thickness and to reduce it the prescribed value.  A prescribed time later after the etchant 16 is dripped, a neutralizing liquid 21 is dripped in the respective recessed parts to neutralize the etching liquid 16, to thereby finely adjust the wall thickness.

Abstract: PURPOSE:To obtain a method which can form a non-alloy type contact layer in a desired pattern without executing a plurality of treatment processes by a method wherein the blank for the non-alloy type contact layer is vapor-deposited in the desired pattern on a semiconductor substrate by utilizing a focused ion beam from a focused ion beam device provided with an ion-beam deflecting function. CONSTITUTION:Fine particles extracted from an ion source 11 are accelerated toward the surface of a substrate (m) by means of a potential difference of 30 to 50[kV] given by an accelerating power supply; they are focused by a first electron lens 13a and are changed to a focused ion beam F3. At this stage, ions are selected by using a mass filter 14. The focused ion beam B which has been passed through the mass filter 14 is focused again by using a second electron lens 13b; its direction is adjusted by using a deflecting electrode 15 controlled by a deflecting-voltage control part 26 so as to obtain a desired contact pattern. When the focused ion beam 13 whose direction has been adjusted is passed through a decelerating electrode 16, it is decelerated down to a prescribed energy and is vapor-deposited on the gallium arsenide substrate (m). Consequently, it is possible to form a non-alloy type contact layer by executing one treatment process.
