Title: Removing method for defect of silicon wafer
IPC: H01L21/324
Filed: 1992-03-12
Abstract: PURPOSE:To eliminate the generation of a defect due to Cu contamination on a surface layer at the time of heat treating in a wafer process. CONSTITUTION:When a silicon wafer is heat treated in a nonoxidative gas atmosphere by using a hot wall type heat treating furnace, the wafer is previously wet oxidized at 1000 deg.C or higher for 5min or more and dry oxidized for 10min or more, and an oxide film is then removed by etching. Thus, when it is altered to SiO2 due to oxidation of lattice Si, Si among the lattice is increased in an Si bulk to suppress the generation of BMD. Accordingly, the generation of BMD is suppressed at the time of heat treating in the atmosphere, and Cu generated from the furnace is not accumulated on the wafer.

Filed: 1990-04-02
Abstract: PURPOSE:To accurately detect a rotational frequency without using any power source by interposing a free rotation section in the joint part between a driven shaft and a driving shaft and rotating a rotor speedily precedently to the driving shaft. CONSTITUTION:When the driving shaft 18 rotates, a male joint part 20 contacts a female joint part 19 and the rotary torque of the shaft 18 is transmitted to the side of the driven shaft 18 to rotate the rotor 12. When the rotor 12 rotates, the magnetic pole of the rotor 12 moves to the neutral point side. After the rotor 12 passes the neutral point, the rotor 12 is rotated speedily precedently to the shaft 18 as the rotor 12 and a stator core 13 are driven with a magnetic attracting force since the gap B is formed as the free rotation gap between the joint parts 20 and 19. At this time, a cross cross-linkage magnetic flux quantity per unit time becomes large abruptly. Then a coil 14 outputs a high- voltage signal by an increase in dphi/dt and the rotational frequency can accurately be detected.
