Title: Semiconductor device
Inventor: HARADA SHIGERU
IPC: H01L21/768
Filed: 1985-06-10
Abstract: PURPOSE:To obtain a semiconductor device having high migration resistance and high reliability in which no defect phenomena of the aluminium alloy wiring occurs, by making the compressive stress of a silicon nitride film by the CVD method as the final protective film or the inter-layer insulating film not greater than a specific value. CONSTITUTION:In a semiconductor device employing a silicon nitride film which has been formed by means of the plasma CVD method as the final protective film 13, 17 or the inter-layer insulating film 15 in a multilayer wiring, the compressive stress of said silicon nitride film is made not greater than 5X10<9>dyne/ cm<2> on the basis of conversion to 1mum film thickness. The defect phenomena of aluminium alloy wirings 2, 4, 6 becomes easier to occur as the compressive stress of plasma CVD silicon nitride films 13, 15, 17 becomes greater and as the film thickness becomes greater. However, the defect phenomena does not occur if the compressive stress is not greater than 5X10<9>dyne/cm<2> for the film thickness of 1mum, not greater than 2.5X10<9>dyne/cm<2> for the film thickness of 2mum, and not greater than 10X10<9>dyne/cm<2> for the film thickness of 0.5mum. A method for making the compressive stress of the plasma CVD nitride film small is, for instance, to make the pressure at the formation of the film high.

Title: Flaw-detecting method by oblique supersonic wave for small-diameter welded pipe and the like
Inventor: SHIMADA KATSUHIKO
IPC: G01N29/04
Filed: 1979-09-29
Abstract: PURPOSE: To improve the credibility of flaw detection by a method wherein a plurality of probes which have high detecting sensitivity for each flaw and whose incident angle of supersonic waves is different from each other are arranged so as to detect each of inside and outside flaws separately.  
     CONSTITUTION: As probes for detecting outside flaws are employed six of them situated symmetrically to the right and left. Refraction angles A, B and C of the probes are selected, for instance, to be 45°, 30° and 60° respectively so that A, B and C of supersonic-wave beams injected obliquely into a pipe 1 respectively are propagated, while being reflected and bent, inside the pipe 1 and reach the outside surface P of the welded part thereof. When any flaws exist in this part, they are detected at the maximum as flaw echoes by the probes of the supersonic-wave beams injected at the angles nearest to the perpendicularity to the directional properties of the flaws, i.e. the angles of inclination. Probes A', B' and C' are arranged symmetrically to the probes A, B and C, respectively. Moreover, probes E, E', F, F', G, G' for detecting inside flaws and probes D, D' for detecting flaws on inner quality are arranged and the flaws are detected separately by a similar method.
