Title: Measuring method of base line offset value and reticle used for it
Inventor: TSUKAGOSHI MASAKI
IPC: H01L21/30
Filed: 1982-06-02
Abstract: PURPOSE:To measure a base line offset value accurately by using a reticle provided around an alignment mark for a reduced-size projecting and exposing device where the alignment position and an exposure position are spaced. CONSTITUTION:A stage 2 reciprocates along the base line offset value l between the alignment position A and exposure position B. The alignment mark 6 of the reticle 4 and the mark formed previously on a wafer 1 are utilized at the position A for alignment and then photoresist on the surface of the wafer 1 is exposed and developed at the position B to measure the deviation epsilon between a present reference mark 8 and a mark 6 formed in this time. The mark 6 is in the center of the reticle 4, so the distortion of a lens in exposure is zero according to the lens characteristics and the position relation between A and B is therefore adjusted so that the deviation epsilon which is variation in offset value l is eliminated. Thus, two patterns have no deviation and the yield is improved.

Title: Pre-format disk inspecting device
Inventor: SHIMOBAYASHI MASARU
IPC: G11B20/18
Filed: 1984-05-10
Abstract: PURPOSE:To protect pre-format information without relying on the mounting condition of a disk single plate and without errors due to medium defects on the signal plate, by detecting the phase difference between one pre-format information and an approaching equiangle position signal and generating a pre-format information gate signal. CONSTITUTION:An approaching equiangle position signal detecting section 3 divides the frequency of an equiangle position signal 6 detected by an equiangle position signal detecting section 1 and selects an approaching equiangle position signal 8 out of the frequency divided signals by using a pre-format detecting signal 7 detected by a preformat detecting section 2, and then, outputs the signal 8 to a pre-format information position detecting section 4 and pre-format information protecting section 5. The detecting section 4 detects the phase difference between the signals 8 and 7 during the period when a selected cycle signal 10 exists and sends the phase difference data 9 to the protecting section 5. The protecting section 5 protects the pre-format information from the re-writing operation by generating a gate signal.

Title: Conveying mechanism for thin member
Inventor: ICHIKAWA KOJI
IPC: G03B1/48
Filed: 1989-04-12
Abstract: PURPOSE:To apply the preset strength to a film in the conveying direction and avoid jamming by curving a plate member forming a passage conveying a thin member such as a film. CONSTITUTION:When a film F is conveyed in the auxiliary scanning direction, the film F is conveyed in a curved shape after the curved shape of plate members 38a and 38b. They are curved perpendicularly to the conveying direction in particular, thus strength is applied to the film F in the conveying direction. Even if such a phenomenon occurs that static electricity is generated by the friction between the film F and the insides of the plate members 38a and 38b and part of the film F is sucked, the film F is made so-called strong- kneed, thus it can smoothly pass between the plate members 38a and 38b. The film F is stably fed to an exposing section.

IPC: H01L21/22
Filed: 1985-05-01
Abstract: PURPOSE:To enable accurate control of the quantity of the liquid material to be vaporized with the set temperature of the liquid material and the flow rate of the carrier gas to be introduced, by inserting a tube into the liquid material, which tube has a sufficient length for the temperature of the introduced gas to become equal to the temperature of the liquid material.

The dip tube 5 is folded several times below the liquid surface 6 of the liquid material. The temperature of the carrier gas introduced into the dip tube becomes equal to the set temperature of the liquid material during the passage through the portion below the liquid surface 6, and then the carrier gas is discharged into the liquid material. For more positive heat exchange between the carrier gas and the liquid material, it is only needed to provide the dip tube with a sufficient length and a thin radial thickness. The design for these may be decided in dependence on the set temperature of the liquid material and the quantity of the carrier gas to be introduced.
