Filed: 1987-07-30
Abstract: PURPOSE:To stabilize the operation characteristics of a transistor such as threshold voltage and ON current-off current ratio by providing between the active layer and the insulating substrate an insulating film of a double-layer structure which is composed of a phosphorus-silicate glass film and a SiO2 film. CONSTITUTION:In a thin film transistor (TFT), a PSG film 10 and a SiO2 film 17 are formed in double layers on an insulating substrate 1 of quartz, pyrex or the like. On this insulating film of a double-layer structure, an active layer 5 made of an amorphous silicon thin film or polysilicon thin film is formed, and a gate oxide film 4, a gate electrode 6, a source 2 and a drain 3 are formed. With this, the diffusion of the impurity contained in the insulating substrate 1 is prohibited by the PSG film 10 and the SiO2 film 17, and the probability of the active layer 5 being contaminated by the impurity from the substrate is substantially reduced, whereby the operation characteristics of the transistor such as threshold voltage, ON current and OFF current become stable.

IPC: A61N2/08
Filed: 1994-07-21
Abstract: PURPOSE:To stably hold the configuration of a bracelet while facilitating the attachment of the bracelet to one's arm by providing a rising part on a slit. CONSTITUTION:A bracelet body is first made of a metallic strip-like sheet formed like a pipe or of a thin wall pipe having a nearly circular section and formed longitudinally with a slit 3. Next, the ends 2 of the slit 3 are rounded inside to from rising parts 4 and obtain a long pipe formed with two hollow portions parallel thereto, while the long pipe is rounded longitudinally to obtain a ring-like bracelet body 1. Thus, since such ring-like bracelet body can be opened perpendicularly to a plane including the ring sufficiently irrespective of the increase in the spring elasticity of the base metal due to the provision of the rising part on the slit 3, the ring opening motion is accompanied by unexpectedness, while the removable attaching operation is facilitated. Also, the occurrence of deviation of the ring opening part caused by the weight of the bracelet 1 itself and decoration body can be blocked.
