Abstract: PROBLEM TO BE SOLVED: To grow selectively a thin film in the parts only which is irradiated with synchrotron radiation by a method wherein material gas is introduced on a substrate cooled down to the temperature of the solidification point or lower of the material gas to form a molecular solid adsorption layer on the substrate and thereafter, the gas is exhausted and the synchrotron radiation is irradiated on the molecular solid adsorption layer. SOLUTION: A semiconductor substrate 1 put in a vacuum is cooled down to the temperature of the solidification point or lower of material gas consisting of the constituent element of a thin film, which is inclined to deposit. Then, the material gas is introduced on the substrate to form a molecular solid adsorption layer 2 on the substrate 1 put in the vacuum and thereafter, the material gas is vacuum-exhausted. Then, after an X-ray mask 3 is aligned with the substrate 1, synchrotron radiation is irradiated on the layer 2 from the vertical direction to make a reaction cause in the layer 2. After the irradiation is fully performed, the mask 3 is removed. Thereby, a thin film region 4 consisting of a constituent substance is formed of the irradiated parts only.  When this substrate is returned to room temperatures, a solid, which is condensed in the non-irradiated parts, is evaporated and the thin film is left in the irradiated parts only.

Title: Method for outputting encoder signal
Inventor: KUBOTA MUNEAKI
IPC: G01D5/244
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To enhance reliability of an encoder by comparing an integrated value of incremental code constantly with an absolute value of absolute code to determine the difference and outputting a flag when the difference is higher or lower than a set value. SOLUTION: An incremental code I obtained from an absolute encoder 1 is inputted to an operating section 5 which delivers an integrated value Ia to a comparator 6. Absolute value of an absolute code A is inputted directly to a comparator 6 and the difference D from the integrated value Ia is returned back to the operating section 5 from where a flag F indicative of presence of the difference D is delivered. A decision can be made, on the user side, whether an encoder signal delivered from the operating section 5 is acceptable or not by detecting the flag F. Alternatively, the flag F may be outputted when the difference D is higher or lower than a set value continuously. Reliability can be enhanced by deciding whether the integrated value Ia is acceptable or not.
