Title: Gas discharge tube
Inventor: IKEDO TOMOYUKI
IPC: H01J61/073
Filed: 1995-03-01
Abstract: PURPOSE: To make deformation hardly cause even under high temperature due to the long-hour continuous emission by sandwiching a positive electrode part by spacers, and holding the positive electrode part between a back face of a convergent electrode support member and a front face of a positive electrode support member. CONSTITUTION: Trigger voltage is impressed between a hot cathode 31 and a positive electrode 24b. A thermoelectron emitted from the hot cathode 31 then passes through a slit 32a of a discharge rectifying plate 32, and reaches the positive electrode 24b while converging by a convergent opening 29a of a convergent electrode part 29. Arc discharge is generated in front of the convergent opening 29a, and an ultraviolet ray taken out of an arc ball by this arc discharge is emitted outside by passing through a peripheral surface of a vessel after passing through an opening window 30. Since a positive electrode part 24 and the convergent electrode part 29 become high temperature, this heat is radiated outside at proper time.  Since the positive electrode part 24 is held in a positive electrode support member 22 by spacers 50, deformation is hardly caused even under high temperature due to the long-hour continuous emission, and positional accuracy between the positive electrode part 24 and the convergent electrode part 29 is excellently kept.

Abstract: PURPOSE:To accelerate a reaction speed by employing as an excitation light source a halogen gas discharge tube and introducing gas containing as a main ingredient the same halogen gas as the gas sealed in the tube as a sensitizer in a reaction chamber. CONSTITUTION:When polycrystalline silicon is etched by an optical excitation etching, an etchant is introduced through a reaction gas introduction tube 4 at a predetermined flow rate into a chamber 3, and Cl2 is introduced as a sensitizer through a halogen gas introduction tube 8 into the chamber 3.

A 100nm thermal oxide film is adhered onto a 4-inch silicon wafer, an n<+>-type polycrystalline silicon is deposited thereon, and a substrate 7 is patterned with resist. When the substrate 7 is etched, its etching rate becomes 15nm/min, thereby obtaining an etching rate of approx. five times as large as that of a conventional method. The same effect is obtained in a case of the material to be etched being not only the polycrystalline silicon but a single crystalline silicon and other material.
