Patent number: 7808099Abstract: A liquid thermal interface (LTI) including a mixture of a linearly structured polymer doped with crosslinked networks and related method are presented. The LTI exhibits reduced liquid polymer macromolecule mobility, and thus increased surface tension. An embodiment of the method includes mixing a crosslinker with a linearly structured polymer to form a mixture, wherein the crosslinker includes a base agent including a vinyl-terminated or branched polydimethylsiloxane, and a curing agent including a hydrogen-terminated polydimethylsiloxane; and curing the mixture.

Patent number: 4692205Abstract: The use of silicon-containing polyimide as an oxygen etch barrier in a metal lift-off process and as an oxygen etch stop in the fabrication of multi-layer metal structures is described. In practice, a lift-off layer is applied on a substrate, followed by a layer of silicon-containing polyimide and a layer of photoresist. The photoresist is lithographically patterned, and the developed image is transferred into the silicon-containing polyimide layer with a reactive ion etch using a CF.sub.4 /O.sub.2 gas mixture. The pattern is transferred to the lift-off layer in a reactive ion etch process using oxygen. Subsequent blanket metal evaporation followed by removal of the lift-off stencil results in the desired metal pattern on the substrate. In an alternate embodiment, the silicon-containing polyimide can be doped with a photoactive compound reducing the need for a separate photoresist imaging layer on the top.Type: GrantFiled: January 31, 1986Date of Patent: September 8, 1987Assignee: International Business Machines CorporationInventors: Krishna G.
