摘要:
An oxygen permeability measuring apparatus for measuring an oxygen permeation rate of oxygen barrier film in a dark room is provided. A container is charged with inert gas, and sealed hermetically by use of the oxygen barrier film at least partially. A chemiluminescent compound is contained in the container, for emitting light by oxidation with the oxygen. A photon detector detects photons emitted by the chemiluminescent compound so as to determine an amount of the oxygen permeated through the oxygen barrier film. Preferably, the container includes a container body. An opening is formed in the container body, and closed hermetically by the oxygen barrier film attached thereto. The photon detector is disposed inside or outside the container. The oxygen permeation rate is equal to or less than 10−2 cc/m2·day·atm. The chemiluminescent compound includes tetrakis(dimethylamino)ethylene.

The objective is to present compositions obtained by supporting by polymers micro clusters of transition metals and the like that are useful as catalysts in various reactions and, once used, are readily recovered and reused.A polymer-supported metal cluster composition is obtained by supporting a transition metal by a cross-linked polymer, and the polymer-supported cluster composition is characterized by the cross-linked polymer obtained by cross-linking of a cross-linkable polymer containing a hydrophilic side chain and a hydrophobic side chain group having a cross-linkable functional group. This polymer-supported metal cluster composition is, for example, preferably formed by first forming a micelle composed of the metal clusters supported by the cross-linkable polymer in a suitable solution and subsequently subjecting the cross-linkable polymer to a cross-linking reaction. The composition is useful as a catalyst and the like in hydrogenation reactions, dehydrogenation reactions, allylic substitution reactions, oxidation reactions, coupling reactions and carbonylation reactions.

A two-photon absorbing optical recording material comprising at least one two-photon absorbing compound and a recording component is provided. Recording is made on it by utilizing the two-photon absorption of the two-photon absorbing compound in the material, and then the material is irradiated with light to thereby detect the difference in the reflectance between the recorded area and the unrecorded area thereof, and the recorded information is thereby reproduced from the material, and also provided are a photosensitive polymer composition and a photon-mode recording method for the material.
摘要:
A gate insulating film (13) is formed on a substrate (1) so as to cover a gate electrode (11), and an amorphous silicon film (semiconductor thin film) (15) is further formed. A light absorption layer (19) is formed thereon through a buffer layer (17). Energy lines Lh are applied to the light absorption layer (19) from a continuous-wave laser such as a semiconductor laser. This oxidizes only a surface side of the light absorption layer Lh and produces a beautiful crystalline silicon film (15a) obtained by crystallizing the amorphous silicon film (15) using heat generated by thermal conversion of the energy lines Lh at the light absorption layer (19) and heat of the oxidation reaction. This provides a method for crystallizing a thin film with good controllability at low costs achieved with simpler process.

A method of manufacturing a semiconductor device includes the steps of: modifying a semiconductor film by applying a laser beam; and forming a semiconductor device on the modified semiconductor film. In the step of modifying the semiconductor film, the laser beam and the substrate are moved relative to each other in a first direction and a second direction which is opposite to the first direction, a change in an optical characteristic between an area irradiated with the laser beam and an area which is not irradiated with the laser beam in the substrate or an optical characteristic of the irradiated area is measured in each of the first and second directions, and irradiation power of the laser beam is modulated so that the difference between a measurement result in the first direction and a measurement result in the second direction lies in a predetermined range.
