Title: Insulating gate type field effect transistor
Inventor: OKABAYASHI HIDEKAZU
IPC: H01L29/423
Filed: 1978-08-08
Abstract: PURPOSE: To make a gate electrode of the film of, or the complex film containing, the nitride of a high-melting point metal or an alloy thereof for reducing the unstability thereof with respect to alkali ions and preventing the generation of stress at the interface thereof with insulating film.  
     CONSTITUTION: A gate electrode 11 is made of the Mo x N y  layer of the nitride of a high-melting point such as Mo for example. The nitride M x N y  of said high melting point metal functions as a more reliable barrier against the diffusion of impurities such as alkali ions than that offered when said high melting point is used separately. Therefore, said gate electrode 11 can be reduced in the unstability due to the alkali ion of a metallic gate construction and improved in reliability, and is superior in oxidation resistance to said high melting point metal. Further, the close contact thereof can be attained with most of the kinds of substrates so that stress can be reduced very small by selecting proper nitriding degree. If said gate electrode 11 is made of two wafer layers of the nitride of a high melting point such as Mo x N y  film 21a and Mo film 21b for example and of a high melting point metal, the resistance value thereof can be decreased smaller than one several-th.

Title: Method of welding for preventing low temperature crack
Inventor: TAMURA KOUJI
IPC: B23K31/00
Filed: 1978-08-11
Abstract: PURPOSE: To prevent traverse crack due to low temperature and short time heat treatment by welding plates up to a specific thickness, treating them by heat and moreover welding them in the whole thickness.  
     CONSTITUTION: When plates are welded by 3/4W4/5 of plate thickness their heat treatment is carried out. Then they are welded in the whole thickness. It is known that releasing time of hydrogen is in proportion to the square of plate thickness. Now, if t is the time taken while the total plate thickness T is welded, heat treatment after welding is carried out and hydrogen quantity reduces until traverse crack can be prevented and if the after-heat treatment is performed when they are welded by 3/4TW4/5T, the time of the heat treatment after the welding capable of preventing the traverse crack will reduce to 9/16tW16/25t. That is to say, the traverse crack can be prevented by about half heat treatment time as much as the heat treatment time after the plates are welded in the whole thickness. Regarding the remnant thickness 1/4TW1/5T, the increase of welding layers scarcely enlarges hydrogen weight.
