摘要: Dimethylformamide mg.multidot.produced by reaction of monomethylamine and trimethylamine at a molar ratio of trimethylamine to monomethylamine of 0.1-10, with carbon monoxide in the presence of 1-500 mg. atom of at least one of iodine, bromine, iodides and bromides as a catalyst in term of halogen per one mole of raw material methylamines at a temperature of 100.degree.-350.degree. C. under a pressure of at least 50 kg/cm.sup.2 gage. Dimethylformamide is produced in a very high yield with a high selectivity from monomethylamine and trimethylamine having less demand among three species of methylamines formed from methanol and ammonia.

摘要: Method and device for cutting a wire with a small number of processing operations. The method includes forming a cut portion by scanning the semiconductor substrate with a focused ion beam to cut the wire. The method further includes forming a clear region continuously from the cut portion by scanning the semiconductor substrate with the focused ion beam. The clear region is free of stray material of the wire.
