Inventor: YATSUDA HIROMI
IPC: H01L25/04
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To provide an electronic component which can decrease the occupation area on a circuit board. SOLUTION: The electronic component 100 comprises SAW(surface acoustic wave) chips 4, 6 flip-chip mounted on the chip mounting faces 8, 10 of a package 2.

Title: Plate type display unit
Inventor: NONOMURA KINZO
IPC: H01J29/46
Filed: 1987-10-09
Abstract: PURPOSE:To simplify an electrode structure as well as to aim at the abatement of material cost by what a control electrode group is dividedly set up as a plane electrode at each linear electron beam source, and a vacuum envelope is provided with such film thickness that has pressure resistance against external atmospheric pressure. CONSTITUTION:A plate type image display unit performs vertical scanning by controlling the electron emission of a linear cathode 2 in order from top to bottom of a faceplate. An electron beam emitted is drawn out by a control electrode group 3, and it collides with an anode 5 installed in a phosphor where the beam is applied to an RGB color system in swing stripe form by a horizontal deflecting electrode 4, thereby developing a desired color in option. In addition, this electrode group 3 is dividedly set up as a plane electrode corresponding to the cathode 2. Each electrode is built in a vacuum envelope which is formed with a glass vessel of about 10mm in plate thickness, and it has pressure resistance against external atmospheric pressure without using any column structure. An electrode structure is thus simplified and, what is more, material cost is reducible in this way.

Abstract: PURPOSE:To measure a durability of an insulating film caused by a stress of an electric current in conformity with an actual operation state by a method wherein an electric current flowing to the insulating film is increased stepwise until a dielectric breakdown is caused and a reliability test of the insulating film is carried out. CONSTITUTION:An SiO2 film is formed on a semiconductor substrate X; the film is an insulating film W as an object of a test. An electric current is made to flow to electrodes 2, 3 from a current source 1. In this case, a magnitude of the electric current flowing from the current source 1 is controlled by an electric-current control circuit 4; an electric current (i) is increased by a prescribed amount every time a definite time elapses. Then, in a process where the electric current (i) is increased stepwise, the insulating film W is deteriorated by an electric charge passing through it; a dielectric breakdown is finally caused. When the dielectric breakdown is caused, the electrodes 2, 3 are set to a short- circuited state, and the circuit 4 stops an operation of an hour meter 6. A charge-amount integrating circuit 7 computes a total charge amount generated until the dielectric breakdown is caused. Thereby, a limit of the dielectric breakdown can be detected properly and the time is not required for a measurement.
