Low dielectric constant insulating material, and electronic part

Abstract: The present invention aims to provide a low dielectric constant insulating material which enables high-speed propagation of signals and is suitable as a material for multilayer circuit wires in an electronic part such as a semiconductor element or the like. The low dielectric constant insulating material of the present invention has an atom having a valency of four or more, and at least two cyclic compounds form a cyclic structure with the atom. Aspects such as that the atom having a valency of four or more is one of a carbon atom, a silicon atom, a nitrogen atom, a phosphor atom and a sulfur atom, that the atom having a valency of four or more is a spiro atom, that the atom having a valency of four or more is in sp3 valency state, and the like are preferable.

Possible but not probable :A quantitative analysis of valency behaviour of Czech nouns in the Prague Dependency Treebank

Abstract: Abstract In order to optimize corpus searches for valency lexicon production, we analyse the relative frequencies of different combinations of valency complementations of Czech deverbal nouns in the Prague Dependency Treebank, considering differences between productively and non-productively derived nouns and their semantic class. We also classify combinations of forms of participants according to their frequency.
