Abstract: PROBLEM TO BE SOLVED: To allow the magnetic field intensity on a wafer to be etched is 300 Gauss or less, and eliminate the charge up damage of the wafer to be etched by lowering the floating potential difference between the center and periphery of the wafer. SOLUTION: Magnetic field feeding coils 6, 7, 8 for feeding magnetic fields into an etching chamber 4 of the apparatus are controlled so as to allow the magnetic field intensity to be 300 Gauss or less on a wafer 10 to be etched or to be treated otherwise, and the charge up damage of the wafer being etched can be eliminated by lowering the floating potential difference between the center and the periphery of the wafer. In a plasma process such as etching process, etc., applied to the wafer 10, lowering the magnetic field intensity on the wafer to 300 Gauss or less reduces the floating potential difference on the wafer and eliminates the charge up damage of the wafer being etched or treated otherwise.

Title: Adjustment of static convergence of electromagnetic focusing cathode-ray tube
Inventor: SAKURAI SOUICHI
IPC: H01J9/44
Filed: 1980-02-04
Abstract: PURPOSE:To perform rough adjustment of static convergence easily by providing a magnetic field generating means for generating a beam focusing field between magnetic yokes while adjusting the relative position in axial direction against a pair of magnetic yokes. CONSTITUTION:The electron beam from a cathode 2 is focused by means of the first and third grinds 3, 4 and after forming a crossover it is accelerated by a magnetic yoke 5 applied with anode voltage to reach to a fluorescent face 14. While the magnetic yoke 5 will absorb the flux from a permanent magnet 8 to produce a focusing field at the gap section thus to form a magnetic main lens 17. The rough adjustment of the convergence is performed such that the position of the permanent magnet 8 is moved in axial direction then the field on a side beam orbit departed from the axis is adjusted. Consequently the convergence adjustment can be performed easily without requiring the field direction adjustment of a four pole field generator 15.

Abstract: PURPOSE:To obtain a phase synchronization type semiconductor laser array device characterized by high output power in a TJS type, by forming a plurality of active regions by a plurality of laminated active layers and clad layers, and first- and second-conductivity type regions, which divide the conductivity types of the active layers and the clad layers into two parts. CONSTITUTION:A Zn diffused P region is provided at a part directly beneath a P-side electrode 21 in clad layers 14-16 and active layers 17 and 18. Said P region 23 comprises a low-concentration P region 24 at the outer surface and a high-concentration P<+> region 25 at the inside. A current is made to flow between the electrodes 21 and 22. Then the current, which flows into a laser, selectively flows only through the active layers 17 and 18. Because the diffusion potential of the P-N junction formed between the clad layers 14-16 is larger than the diffusion potential at the first active layer 17 and the active layer 18. The inputted current results in radiation and recombination in active regions 27 and 28, and laser light is emitted. At this time, the thickness of the clad layer 15 is made as thin as several mum. Thus the laser light emitted from the active regions 27 and 28 can be synchronized in phase.
