摘要:
Thick flim resistors and conductors compatible with copper and fireable in nonoxidizing atmosphere are provided. The resistors are based on certain hexaboride conductors such as LaB.sub.6 and glasses which are thermodynamically stable to or nonreducible by the hexaborides. Thick film pastes prepared with small particle size hexaboride and certain ethylene-vinyl acetate polymeric vehicles afford resistors having improved temperature coefficient of resistance and coefficient of variation.

摘要:
A decoupling capacitor for highly integrated, fast switching logic circuit modules. The capacitor comprises stacked ceramic sheets having metallized surfaces. The sheets are connected together in groups. Alternate groups are connected to a first electrode. Intervening alternate groups are connected to a second electrode. The connections are all made to the same ends of all the sheets so that the current flows in opposite directions through adjacent facing plates.
