Abstract
Abstract An inorganic chip-to-package interconnection circuit is described. The circuit has a set of electrical conductors that are held together by a set of insulating inorganic tie bars. The circuit constitutes a high-density chip-to-package interconnection circuit that does not absorb vapor or volatile gases. A variety of methods for forming the circuit are described. Advantageously, the methods utilize known processing techniques.
