IPC: H01L23/52
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent electric connection errors between multilayer wirings even when misalignment between masks is generated, by forming a dummy pattern which is electrically connectable with a contact hole, on the periphery of the contact hole. SOLUTION: An interlayer insulating film 12 is formed on a semiconductor substrate 11, and a first metal wiring 13 is formed on the interlayer insulating film 12. On the entire surface of the interlayer insulating film 12 including the metal wiring 13, a second insulating film 14 is formed. After nitride film patterns 15, 15' having a predetermined width are formed on the second insulating film 14, a transition metal film 16 is evaporated with a thickness large enough to fill the portion between the patterns 15, l5'. Then, etch back is carried out until the surfaces of the patterns 15, 15' are exposed, thus forming a dummy pattern 16. Subsequently, after a contact hole 18 for exposing the surface of the metal wiring 13 is formed, a tungsten film is evaporated on the entire surface including the contact hole 18.  The tungsten film is etched back until the surface of the pattern 15 is exposed, thus forming a tungsten plug 19.

Title: Production of titanium alloy ingot containing nickel
Inventor: TAKI CHIHIRO
IPC: C22B9/20
Filed: 1991-12-25
Abstract: PURPOSE:To avert the dislodgment of a part of an electrode in arc secondary melting of a nickel-contg. titanium ingot.

Title: Method for reducing fluorine in steel making slag
Inventor: MIYATA YASUTO
IPC: C21C5/28
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To suppress elution of fluorine at the time of reuse without requiring a long term waiting of natural elution or reduction of fluorite being used as a slag making material by crushing a steel making slag into required size and spraying normal temperature water to the slag at a specified weight ratio. SOLUTION: A steel making slag is crushed into required size and sprayed with normal temperature water at a rate of 10 kg or more per 1 ton of slag. When a steel making slag containing CaF2 is sprayed with normal temperature water and brought into contact with water, fluorine eludes into the water in the form of ions and the content of CaF2 decreases. When hot water of 50 deg.C or above or steam is sprayed in place of normal temperature water, reaction rate or solubility is increased and fluorine in the slag can be reduced in a shorter time. It can be carried out conveniently using a hot water aging facility or a steam aging facility for suppressing expansion of slag.
