Patent JP-S59203354-A (JP)
Title: Scanning electron microscope
Inventor: KANDA KIMIO
IPC: H01J37/28
Filed: 1983-05-04
Abstract: PURPOSE:To achieve good adjustment of the deflection center by installing a shunt, having an impedance proportional to the impedance of a deflecting coil, parallel to the deflecting coil. CONSTITUTION:An electron beam 1 is scanned over a sample 4 by being deflected with deflecting coils 2 and 3 incorporated in a mirror body. An objective diaphragm 6 is installed on the main surface of an objective 6. A coil 2 is formed by connecting an inductance (L1) and a resistance (R1) in series, while a coil 3 is formed by connecting an inductance (L2) and a resistance (R2) in series. The coils 2 and 3 are connected in series when used and the same current is fed to them. Correct adjustment of the deflection center can be achieved without controlling the scanning frequency by changing the distribution rate by installing external controlling inductance (L) and resistance (R) parallel to the coil 2. In addition, the impedance of a deflection current regulator is switched correspondingly to the excitation of the lens 6 thereby enabling the deflection center as well as the change of the deflection center caused by change in the excitation of the objective 6 to be controlled.

Title: Direct joint of semiconductor wafer
Inventor: GOTO YOSHITAKA
IPC: H01L21/762
Filed: 1989-03-28
Abstract: PURPOSE:To suppress the creation of voids in the contact boundary between semiconductor wafers by a method wherein warping material films having a thermal expansion coefficient different from that of the wafers are formed on the one side surfaces of the respective wafers and, while the wafers are warped in an atmosphere whose temperature is different from that of the process for forming the warping material films, the whole contact surfaces of both the wafers are brought into contact with each other and the wafers are jointed by applying a current to the wafers. CONSTITUTION:Thermal silicon oxide films 2 and 5 having a thermal expansion coefficient different from that of silicon wafers 1 and 4 to be jointed are formed on one side surfaces of the silicon wafers 1 and 4. While both the silicon wafers 1 and 4 are warped in an atmosphere whose temperature is different from the temperature of the process for forming the oxide films 2, both the silicon wafers 1 and 4 are gradually brought into contact with each other until the contact surfaces are spread over the whole surfaces of the silicon wafers 1 and 4. While the whole areas of the contact surfaces of both the silicon wafers 1 and 4 are brought into contact with each other, SiO2/SiO2 of both the silicon wafers 1 and 4 are directly jointed. Therefore, the contact regions of the silicon wafers 1 and 4 are spread from the center point toward the circumference. With this constitution, the creation of non- contact parts (voids) between the silicon wafers 1 and 4 can be suppressed.

     CONSTITUTION: In an electrostatic focusing type picture tube, the max. diameter of electron beam in an electrostatic focusing lens is approx. 10% of the inside diameter of the fourth lattice 10, which is sufficient with allowance for the third spherical aberration as the aberration for the electrostatic lens, in which the expansion of beam based on the spherical aberration, or the mimimum disturbed circle diameter DC, is related to the spherical aberration coefficient CSP by the formula I, where θ is the divergence angle of beam in the electron beam limited opening 8a and ML is the multiplication of image. The ratio of the effective length l 4  of the fourth lattice 10 to its inside diameter d 4  is set up to l 4 /d 4 =1.15W2.30. Thus, the expansion of the electron beam by the spherical aberration can be improved and excellent definition characteristics can therefore be obtained.
