IPC: H01L29/732
Filed: 1982-08-18
Abstract: PURPOSE:To obtain a bipolar transistor which has high speed and high integration by opening windows at triple films of SiO2, P<+> type polysilicon and Si3N4 on an Si substrate, sidewisely etching the SiO2 film, covering it with a polysilicon, and thermally oxidizing it to isolate the base from the emitter. CONSTITUTION:Triple films of SiO2 12, P<+> type polysilicon 13 and Si3N4 are formed on an N<-> type Si substrate 11, windows are opened by anisotropic plasma etching at the films 14, 13, the film 13 is etched at side surface 16 by isotropic plasma, the film 12 is then wet etched, and overhangs 17 are formed. A polysilicon 18 is accumulated by a pressure reducing CVD method in the amount more than 1/2 or larger than the thickness of the film 12 to bury the overhangs 17, and converted by high temperature wet oxidizing into an SiO2 film 19. At this time the film 13 is diffused through polysilicon 20 to the substrate 11, thereby forming a thin P type base 22. Then, the film 19 is removed by anisotropic etching to open a window 21, and the film 19 is allowed to remain on the side surface. Thereafter, an N<+> type emitter 25 is formed through a P<-> type base 24 and an N<+> type polysilicon electrode 23. According to this structure, a capacity CBC and a base parasitic resistance can be remarkably reduced, thereby enhancing the integration and performance.

Filed: 1987-06-10
Abstract: PURPOSE:To easily detect the existence and degree of gas leakage by making the capacity of an expanded bag larger than the volume of a small-sized bomb in case of sealing the small-sized bomb in a bag made of gas non-permeable resin film. CONSTITUTION:A vacuum pack type small-sized bomb 1 comprises a bag 2 and a small-sized bomb 3 sealed in the bag 2. The bag 2 is made of transparent gas-nonpermeable resin film and sealed up at the peripheral portion 2b by adhesion. The capacity of the expanded bag 2 is larger than the volume of the small-sized bomb 3. When gas leaks from a sealing plate portion 3b, the adhesion of the outer wall 3a of the bomb to the inner wall 2a of the bag is released. When the leakage is further increased, the adhesion is completely released to expand the bag. The existence and degree of gas leakage are detected from the capacity of the adhesion releasing portion and the degree of expansion.

Title: Direct lithography type lithographic printing plate master
Inventor: GOTO KAZUOKI
IPC: G03F7/00
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To improve an image reproducibility by specifying a reflectivity of an illuminated light having the same wavelength as that of a laser beam of a thermosensitive layer of a direct lithography type lithographic printing plate master. SOLUTION: In the case of transmitting an illuminated laser beam through a thermosensitive layer with a transmittance of 20% or more, an adverse influence of a reproduction fault or the like of fine halftone dots according to removal or drop of the layer by an excess supply energy from below the layer and a halation from below might be affected to the layer. Thus, the transmittance of the illuminated laser beam or a light having the same wavelength as that of the illuminated beam to the layer is set to less than 20% so that the illuminated laser beam is scarcely transmitted through the layer. As a method for giving a reflective means to the layer to set the transmittance to less than 20%, there is a method for adding fine particles of a titanium oxide for reflecting the laser beam into the layer.  Meanwhile, in the case of considering a reaction efficiency in the layer, a method for adding a substance for absorbing the beam in the layer as a method for giving an absorptive means is better.
