Title: Measurement of film thickness of semiconductor device
Inventor: SATO ISAO
IPC: H01L21/66
Filed: 1989-02-06
Abstract: PURPOSE:To measure a film thickness of an epitaxial growth layer highly accurately and easily by a method wherein a pattern for measurement use, a deposition layer and an opening part are formed according to a process and are utilized. CONSTITUTION:A dielectric layer other than a pattern 23 for measurement use is removed; after that, a deposition layer 25 composed of a single-crystal silicon layer to which n-type impurities have been added, i.e. an epitaxial growth layer, is formed on a semiconductor substrate 21; then, the deposition layer 25 on the pattern 23, for measurement use, composed of a silicon oxide film is transformed into a polycrystalline silicon layer 26. Then, the polycrystalline silicon layer 25 is dry-etched; an opening part 27 reaching the pattern 23 for measurement use is formed; in succession, the pattern 23, for measurement use, exposed inside the opening part 27 is etched by using a hydrofluoric-acid-based solution; the opening part 27 reaches the semiconductor substrate 21. After that, a difference in level on the surface is measured by using a contact-type surface difference-in-level meter while this meter is scanned on the deposition layer 25 including the opening part 27, e.g. in a direction of an arrow C. Thereby, a film thickness of the deposition layer can be measured by using a highly accurate and easy means.

Title: Disk discriminating device in optical disk device
Inventor: KATAYAMA TAKESHI
IPC: G11B7/004
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide an optical discriminating device of an optical disk device capable of speedily and exactly disrcriminating types of disks and setting a focus because a conventional disk discriminating device has a problem that an object lens has to be moved up and down plural times and it takes a longer spin-up time in setting a focus after disk discrimination. SOLUTION: When exit light from an object lens is made to be set at a focus position on the above disk surface, the type of the disk is discriminated during the process of making the object lens approach to the information plane of the disk, namely, an amplitude value of a 1st layer focus error signal obtained at that time is stored, and based on this stored value, discriminating operation is carried out by detecting the presence or absence of a 2nd layer error signal based, and focus setting operation is performed during the process of moving the object lens away from the information plane of the disk.

Title: Method for coating building board and apparatus therefor
Inventor: MATSUNAGA KOICHI
IPC: B05D7/00
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To improve adhesivenness of a coating film and to provide a building board with natural stone texture, various design properties and high marketability by providing vibration on the building board when a coating prepd. by mixing an aggregate in a synthetic resin vehicle is applied on the surface of the building board with at least a specified difference of unevenness or above. SOLUTION: A building board B is sucked and supported by means of suckers 7 of an up-and-down frame 5, which is vibrated by means of a vibration motor 6. As this vibration is transmitted through the suckers 7, shock is absorbed and the building board B is supported and vibrated, neither being deviated from the supporting position and nor destroyed. In addition, a coating material wherein round- and square- shaped aggregates are mixed in a synthetic resin vehicle is sprayed from a freely movable spray nozzle 10 on the surface of the building board B and the nozzle 10 is moved front and back and left and right to coat uniformly the surface of the building board B. Therefore, the coating material with the aggregates smoothly flows into the recessed parts of the building board B with unevenness of difference in height of at least 30μm or above and adhesiveness between the coating film and the surface of the building board BY is remarkably improved by an anchor effect of the penetrated coating film.
