Title: Wafer cleaning method
Inventor: MIYATA NORIYUKI
IPC: H01L21/304
Filed: 1991-12-26
Abstract: PURPOSE:To provide a wafer cleaning method by which unnecessary elements, such as oxygen, carbon, etc., are not allowed to adhere to the surface of a wafer even when the wafer is left in the air and, at the same time, the scattering of necessary elements, such as fluorine, etc., is prevented. CONSTITUTION:After contaminants, such as carbon, heavy metals, etc., adhering to the surface of a wafer 1 are removed by performing RCA cleansing on the surface of the wafer 1, the wafer 1 is dipped in a boiling mixed solution of an acid, hydrogen peroxide, and pure water so as to form an oxide layer 10 having a thickness of about several atomic layers on the surface of the wafer 1. Then, after the layer 10 is removed by dipping the surface of the wafer 1 in a diluted hydrofluoric acid solution and the surface of the wafer 1 is terminated with hydrogen, the wafer 1 is immediately dipped in a hot hydrochloric acid so that the silicon surface of the wafer 1 can be terminated with chlorine atoms instead of hydrogen.

Abstract: PROBLEM TO BE SOLVED: To terminate a telephone call, which is made to a hand set, through a telephone master set, connected to a cable public line by connecting the cordless telephone master set connected to the cable telephone line and capable of being connected to the cordless telephone hand set with an extension radio line to a portable telephone set, capable of being connected to a public base station with a public radio line through an adapter device. SOLUTION: When a telephone call is terminated through a public radio line WLp and a PHS base station 2 to a PHS hand set 20-h in a dual wait mode, the PHS hand set 20-h is switched to a public mode. The call incoming information is converted into the transmission information of cordless telephone format through a transmission line 45 and transmitted through an extension WLh to a master set 10C of cordless telephone. Thus, the telephone call terminated through the PHS station 2 to the PHS hand set 20-h can be made incoming to the master set 10C, connected to a public cable telephone line LN. Further, speaking is enabled between a persons of line wire 2 and a subscriber house 1.

Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To improve the stability of the amount of light of an optical system with respect to temperature by constituting an optical branching device so that change in the amount of emission light of a light source due to change in temperature may be cancelled out and that the branching ratio changes as the wavelength of the light source changes. SOLUTION: This is a technique to cancel out fluctuation of the amount of light due to locational deviation at the fiber end of a light source part, which is the main factor of fluctuations of the amount of light in an optical system, by the wavelength characteristics of the branching ratio of an optical coupler (optical demnltiplexer). To be concrete, the characteristics that the emission wavelength of a semiconductor light source as a light source is linearly changed by temperature and the characteristics that the branching ratio of an optical coupler is similarly changed to the wavelength are used together to chancel one changes in the amount of light by the characteristics of the branching ratio of the optical coupler.  In other words, the branching ratio of the optical coupler to wavelength is set so that changes in the amount of light due to locational deviation at the fiber ends of a light source due to changes in temperature may be canceled out by change in the amount of light due to changes in the branching ration of the optical coupler due to changes in the wavelength of the light source. As a result, the stability of the amount of light to temperature is increased to improve performance.
