Title: Cold cathode ionization gauge
Inventor: TAKAGI NOZOMI
IPC: G01L21/34
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To make an apparatus compact and light-weight by arranging a magnet inside a vacuum container and constituting an anode or a cathode of the magnet. SOLUTION: A vacuum container 1 is mounted via a flange 2 to a flange 3 of a vacuum container to be measured. An anode 4 is constituted of a cylindrical magnet arranged coaxially with an axis of the vacuum container 1 and connected to an electrode 6 via a connecting part 5. The electrode 6 is fixed to a wall of the vacuum container 1 via an insulating body 7, to which a d.c. voltage of 2 to 3.5kV is applied. Plate-like cathodes 8 are arranged above and below the anode 4. Because of the constitution, an electric field and a magnetic field are present in a space between the anode 4 and cathode 8. When electrons are generated in each space, the electrons collide with a residual gas in the space, bringing about continuous discharging. Since a discharging current depends on the amount of the residual gas, a pressure of the container to be measured can be detected by measuring the discharging current.

Title: Method for measuring film thickness of thin film
Inventor: KINOSHITA TADAYOSHI
IPC: G01B21/08
Filed: 1981-11-05
Abstract: PURPOSE:To measure film thickness accurately, by combining materials characterized by large difference in the adhering force with the film, and providing sharp difference in step in the film formed on a monitor substrate. CONSTITUTION:A glass substrate 1 is used as a monitor, and fixed to a specified position of a jig by which the film is formed by a sputtering method, a gaseous phase growing method, or the like. Cr2 is used as a bonding layer for Au3 and the glass. The sputtering of oxide, nitride, carboide or the like is performed on the Au 3, a part of the glass exposed in a hole, and the substrate 1, and a film 6 is formed. Thereafter, tacky tape is applied to the film 6 and it is taken away. Since the film adhering force is weak on the Au 3 and strong on the glass 1, the film 6 on the Au3 is taken away by the tape. But the film 6 on the glass 1 is not taken away and remains. The Cr2 under the Au 3 is sequentially removed by etching liquid. Then only the film 6 attached on the glass remains. The difference in step of this film is very sharp. When it is scanned by a surface roughness gauge, a clean convex cross section is drawn, and the difference in step, i.e. the film thickness can be obtained readily and accurately.

Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To etch a reflection preventing film against a resist film at practical etch selectivity by using a gas containing CH2 F2 as an etching gas. SOLUTION: After a laminated film, which becomes a substrate 17 to be patterned and is composed of a polysilicon layer 17a and a tungsten silicide layer 17b, is formed on a silicon substrate 11, a reflection preventing film 19 and a photoresist film 21 are successively formed on the substrate 17. Then, after a mask 21a is formed by exposing and developing the photoresist film 21, the part of the reflection preventing film 19 which is not covered with the mask 21a is removed by dry etching. For the dry etching, a mixed gas of CH2 F2 , CF4 , and He is used as an etching gas. Since the CH2 F2 has a relatively high depositing property, the etching of the reflection preventing film 19 is conducted while the mask 21a is protected. Therefore, the film 19 can be etched at practical etch selectivity against the resist film 21.
