Abstract: PURPOSE:To reduce the change in etch rate with time and to prevent an unetched part in a fixed etching time even by using an etching solution both immediately after its preparation and after 24 hours by a method wherein a buffer solution is used for the Ti-etching solution composed of EDTA/hydrogen peroxide. CONSTITUTION:The change in etch rate with time for an etching solution composed of EDTA/hydrogen peroxide is related to the change in a pH value of the etching solution; the etch rate suddenly changes especially if the pH value is below 10; after attention has been directed to this relation, Ti for the formation of an electrode for a semiconductor device or the like is etched by using the etching solution containing ethylendiamine tetraacetic acid, hydrogen peroxide, a compound of ammonium and a buffer agent of ammonium acetate. At this etching solution, the pH value can be maintained in the range of 10-11 even after the solution has been conserved for many hours after its preparation because the buffer agent is contained. As a result, the etch rate is stabilized.

Title: Pulse gas laser
Inventor: ARAI MOTOHIRO
IPC: H01S3/038
Filed: 1987-11-30
Abstract: PURPOSE:To implement a pulse gas laser which can be operated in high repetition and has high efficiency by forming a gap between a spare ionization side electrode and a dielectric member, and constructing to also supply laser gas to the gap. CONSTITUTION:A gap 5 is formed between a dielectric 1 formed on a trigger electrode 2 and a spare ionization side electrode 3 having many holes for passing ultraviolet rays. Thus, since laser gas flows to the gap 5, ionized laser gas or impurities are scarcely stayed, and a decrease in the potential difference between the electrode 3 and the dielectric 1 is reduced. Accordingly, even if it is operated in high repetition, the intensity of the ultraviolet ray generated by a corona discharge on the dielectric 1 is scarcely decreased, the instability of laser excitation due to the decrease in the ionization of the laser gas in the discharge space can be suppressed, thereby improving its efficiency.
