Abstract: A semiconductor device and method of its manufacturing method are provided for realizing smaller low voltage transistors while maintaining the characteristics of high voltage transistors. A first transistor formation region is separated by selectively leaving first element-separating insulator film. A second transistor formation region is separated by selectively oxidized second element-separating insulator film. On the region separated by first element-separating insulator film, a first transistor having a first channel-formation region, first source/drain regions, and first gate-insulation film with a first film thickness and first gate electrode are formed. On the region separated by second element-separating insulator film, second transistors having a second channel-formation region, second source/drain region second gate-insulation film with thickness thinner than the first film thickness, and a second gate electrode are formed.

Abstract: A connective insulating membrane is formed on only the bottom face of the metallic partition wall. The metallic partition wall is positioned in a predetermined position on the substrate with the connective insulating membrane on the bottom face being in contact with the substrate, and a dielectric film is superimposed on the metallic partition wall. With the dielectric film, the metallic partition wall and the back glass substrate thus positioned, a burning process is performed to fuse the connective insulating film with the substrate, whereby the metallic partition wall is secured to the substrate and the metallic partition wall and the exposed faces of the substrate are covered by a dielectric membrane formed of the dielectric film.

Abstract: A plurality of row electrode pairs and a dielectric layer covering the row electrode pairs are formed on the back-facing face of the front glass substrate. Phosphor layers are formed on the front-facing face of the back glass substrate for each discharge cell. Protuberances formed of dielectric are formed on portions of the dielectric layer each opposing a discharge gap between the opposing transparent electrodes of the paired row electrodes. Each of the protuberances extends outward from the dielectric layer into the discharge cell toward the back glass substrate. A floating electrode is formed in the protuberance.

The row electrode pairs and the column electrodes are covered by a first dielectric layer and a second dielectric layer so as to be separated from each other. Each of the recessed trenches is formed in a portion of the first and second dielectric layers between a transparent electrode of the row electrode and the column electrode between which an address discharge is produced in the discharge cell.

Abstract: Row electrode pairs are formed on the front glass substrate of the PDP. Each of the row electrodes constituting a row electrode pair has a bus electrode and transparent electrodes each connected to the bus electrode and initiating a sustaining discharge in conjunction with the other row electrode paired therewith.

A plurality of first additional dielectric layers protrude from the rear-facing face of the transparent dielectric layer, extend in the column direction and are regularly arranged in the row direction. An address electrode initiating a discharge in conjunction with the sustain electrode is formed on each of the first additional dielectric layers.

A second metallic partition wall unit defining the discharge cells adjoined to the first partition wall unit is formed on the back glass substrate.

Abstract: An information recording medium has an excellent jitter characteristic with a considerable difference in reflectance between prior to and subsequent to recording. The information recording medium includes a recording layer which contains a material having a reflectance which varies by irradiation of a light beam, on which information is recorded as reflectance variations, and a substrate for supporting the recording layer, the recording layer including a metal nitride as a major component.

Abstract: A stack “0” having a recording layer serving to transmit a light beam includes a heat dissipating layer, a reflective layer, an enhanced layer, and the recording layer, which are formed in that order on an intermediate layer. The reflective layer is translucent to a light beam, while the heat dissipating layer has a thermal conductivity higher than that of the intermediate layer as well as a refractive index higher than or equal to that of the intermediate layer and less than or equal to a refractive index 3. The thickness of the heat dissipating layer is set to a value within the range of a predetermined condition defined in accordance with a refractive index, the wavelength of the light beam, and a given integer. Thus, an information read/write medium configured to enable information to be recorded/reproduced thereon/therefrom as well as to effectively cool a recording layer serving to transmit a light beam is provided.

Abstract: An optical disc has a recording film with information recorded thereon, and a photochromic material film provided adjacent the recording film. The photochromic material film is made of a photochromic material. The photochromic material has a first state irradiated with reading light having a first wavelength. In the first state, the transmittance of the material is increased so as to enable reading of the recorded information. The photochromic material further has a second state irradiated with auxiliary light having a second wavelength, where the transmittance becomes low so as to disable the reading of the recorded information.
