Title: Semiconductor device
Inventor: FUJII TAKEO
IPC: H01L21/8234
Filed: 1985-07-31
Abstract: PURPOSE:To prevent approaching aluminum wirings from shortcircuiting therebetween by forming a distance between the separating regions of the first and second impurity diffused layers shorter than that between the separating regions of an impurity diffused layer of other adjacent power source potential and an impurity diffused layer of a ground potential. CONSTITUTION:An aluminum wiring layer 109 is connected with a power source pad, and an aluminum wiring layer 110 is connected with a ground pad. Holes 103, 104, 107, 108 are formed to extend in parallel with the approaching regions of adjacent impurity diffused layers 101, 102, the shape of the impurity diffused layer is formed acutely by cutting the corner of the adjacent portions to the approaching region to avoid the concentration of currents. The holes 103, 107 or 104, 108 may be formed at the same position. In this case, the aluminum wiring layer is preferably separated in a certain degree from the approaching region of the layers 101, 102. Thus, when an abnormal voltage is applied to the power source pin of a semiconductor device, a breakdown occurs at the specific portion, and the other impurity diffused layer region is protected.

Title: Ion source
Inventor: NAITOU NORIHIRO
IPC: G01N27/62
Filed: 1981-10-23
Abstract: PURPOSE:To make it possible to independently regulate the pressure inside of a collision chamber from that of an ion gun through simple constitution by supplying Ar gas while forcing it to leak from the collision chamber, concerning an  ion source to be used for a mass spectrograph. CONSTITUTION:A considerable part of ions passing through an inside of a collision chamber collides with Ar atoms to be converted into high speed neutral Ar atoms with almost no change of direction and speed of motion but being deprived of electric charge so that the Ar ions and the neutral Ar atoms are expected to be mixed among the beams passing through said collision chamber.  The Ar ions thereof are deflected by a successively disposed deflector 23 and removed while only the neutral Ar atoms pass through said deflector 23 to be taken out as a high speed Ar atom beam 24. Correct regulation of the pressure P2 of the Ar gas for ionization can be performed by changing an opening of a valve 4 independently from the regulation of the Ar pressure P1 inside of the collision chamber by operating the valve 22.
