Title: Semiconductor silicon wafer carrying retention tool and semiconductor process device using the same
Inventor: TAMURA KAZUYOSHI
IPC: B25J15/06
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the diffusion of an impurity from a retaining tool and prevent the particles and contamination from being generated when the wafer is exposed to an etching gas and a plasma gas, by forming the retaining tool of a carrying device with silicon with the same material as a wafer. SOLUTION: While a gas in a vacuum chamber 12 is being evacuated from an exhaust pipe 13 through a vacuum pump, a semiconductor silicon wafer W is vacuum chucked by a porous suction plate 11. Then, after it has been carried to a specific position by a robot, vacuum is released and the wafer W is allowed to leave the pours suction plate 11. In this case, although an entire vacuum suction device 10 is made with a single-crystalline silicon, only the porous suction plate 11 that directly touches the wafer W may also be manufactured with single-crystalline silicon. In the manner, by forming a chucking tool with silicon with the same material as the wafer W, the generation of particles and contamination when the wafer is exposed to an etching gas and a plasma gas can be prevented, thus improving the manufacturing yield of the wafer.

Abstract: PURPOSE:To obtain a blood flow speed image on the basis of the blood flow speed by forming an interposed layer between a vibrator element and a backing member and reducing the sound impedance of the interposed layer smaller than that of the backing member and setting the thickness of the layer to 1/4 of the wave length of the generated supersonic wave. CONSTITUTION:The back surface of a piezoelectric element 1 is supported by a backing member 2, and the base board of the piezoelectric element 1 is formed, and the supersonic wave supplied from the back surface of the piezoelectric element 1 is prevented from returning to the piezoelectric element surface again. Further, an interposed layer 3 is installed between the piezoelectric element 1 and the backing member 2, and the sound impedance is reduced to be smaller than that of the backing member 2, and the thickness of the interposed layer 3 is allowed to correspond to 1/4 of the wave length of the supersonic wave generated from the piezoelectric element 1. Accordingly, the phase difference of half the wave length of the supersonic wave is generated between the supersonic wave supplied from the back surface of the piezoelectric element 1 and the reflection wave reflected in the boundary part between the interposed layer 3 and the backing member 2. Thus, the synchronization with the supersonic wave generated by the piezoelectric element 1 itself is realized, and the ultrasonic wave vibration having the long duration time is obtained, and the blood flow speed can be measured correctly, and a blood flow speed image is obtained on the basis of the measurement.
