Silicide - Wikipedia
网页A silicide is a type of chemical compound that combines silicon and a usually more electropositive element. Silicon is more electropositive than carbon. In terms of their physical properties, silicides are structurally closer to borides than to carbides.
What Are the Silicides? - SpringerLink
网页2019年7月17日 · Silicides are a group of compounds, comprising silicon in combination with one or more metallic elements. These hard, crystalline materials are closely related to inter-metallic compounds and have, therefore, many of their physical and chemical characteristics and some of the mechanical properties of metals.
网页Introduction. Silicides have been used in self-aligned (SALICIDE) processes for several genera-tions of complementary metal-oxide semiconductor (CMOS) devices, to reduce the sheet resistance and provide stable ohmic contacts with low contact resistivity on gate, source and drain areas [1–9].
网页Silicide-related studies have primarily focused on the investigation of fundamental properties such as electrical resistivity, high-temperature stability, and corrosion resistance, as well as the silicide crystal chemistry and metal-silicon phase diagrams.
Silicide - an overview | ScienceDirect Topics
网页The chemical bonds in silicides range from conductive metal-like structures to ionic or covalent. Silicides of all nontransition metals, with exception of beryllium, have been described. Group 1 and 2 silicides, e.g. Na 2 Si and Ca 2 Si, react with water to yield hydrogen and/or silanes.
