Abstract: PURPOSE:To reduce the irregularity of oxide film thickness, and the impurity concentration in a batch and in a wafer surface, by controlling gas flow in a wafer processing part at the time of wafer processing. CONSTITUTION:A specified species of gas is made to flow into a process tube 1 from a gas feeding pipe 4, and reaction is induced by heating wafers 3 and the gas with a heater 2. Hence the oxidation, diffusion, and thermal treatment of semiconductor devices on the wafers 3 are performed. In these processes, by the action of a gas flow controlling plate 7 arranged on a boat loader 6, the gas flow 8 for wafer processing circulates uniformly on the outer periphery and the surface of the wafer 3, and the new gas flow 8 for wafer processing is always supplied to the wafer 3. By the effect of this action, highly uniform oxidation and impurity diffusion are performed for the semiconductor devices on the wafers 3.

Title: Focus detecting method for optical system of optical pickup
Inventor: EMOTO MASAMI
IPC: G11B7/1381
Filed: 1984-09-06
Abstract: PURPOSE:To attain effective pulling-in of a focus by performing this pull-in operation by means of the output sum signal of the 2nd detection element having convex properties only in a focused state and the output difference signal of the 2nd detection element which is set at zero only in a focused state. CONSTITUTION:The reflected light sent from a disk via an objective lens 5 is received by the 1st detection element 8' by 70-80% and cut off to the 2nd detection element 9. Photodelectric conversion signals SA and SR extracted out of the reception part of the element 9 are supplied to a subtractor 12 and an adder 13 respectively. The output L of a comparator 18 is changed to a high level from a low level when the sum signal of both signals SA and SB exceeds a level set by a reference voltage generating source 17. Then a sequence control circuit 19 changes a changeover switch S14 to a contact (a) after detecting that the output L is changed to a high level. Thus the difference signal between both signals SA and SB is sent to a servo drive circuit 15, and the lens 5 is driven so that the difference signal is set at zero. In such a way, the effective pull-in action is possible with the focus.

IPC: G02F1/025
Filed: 1989-07-21
Abstract: PURPOSE:To efficiently execute the modulation by a small driving voltage by forming an optical waveguide part for propagating a light beam to such an azimuth as the polarity of a refractive index variation portion of a semiconductor layer and the polarity of a refractive index variation portion of a semiconductor crystal for constituting the optical waveguide part become the same by an electric field applied from the outside. CONSTITUTION:Magnitude of wavelength lambda is contained in a wavelength area C, and by applying an electric field based on a power source 9, a refractive index variation portion  n becomes a value of plus, and the refractive index shows an increasing trend. Also, an optical waveguide part 10 is formed in an azimuth of [110], therefore, a refractive index of a semiconductive bulk crystal is also increased by applying the electric field. Therefore, the refractive index of the optical waveguide part 10 is varied greatly since a quantum well effect and an electro-optical effect component of the semiconductive bulk crystal are superposed on each other in the plus direction. In such a way, a large refractive index variation can be induced by a small driving voltage, and the driving voltage can be reduced.
