Title: Hybrid integrated circuit device
Inventor: IGARASHI YUUSUKE
IPC: H01L23/02
Filed: 1992-01-31
Abstract: PURPOSE:To prevent exfoliation of the pad for an external lead in a hybrid integrated circuit, device filled with silicon gel. CONSTITUTION:A case member 10 for sealing an integrated circuit element has substantial frame shape equipped with a pair of walls 14 for partitioning an integrated circuit substrate into an integrated circuit element mounting region 16 and an external lead bonding region 18. Silicon gel is injected, in sol state, into the integrated circuit element mounting region 16 defined by the pair of walls 14 and eventually transformed through heat treatment into silicon gel. The pair of walls 14 prevents silicon sol having high fluidity and permeability from permeating or scattering to the external lead bonding region 13 thus preventing the pad for the external lead from exfoliating due to adhesion of silicon sol to the external lead bonding region 18.
