Patent number: 5529279Abstract: A microactuator preferably in the form of a microminiature valve for controlling the flow of a fluid carried by a flow channel includes a first substrate having a thermally-actuated member selectively operated by a thermal actuator such that the first substrate thereby develops thermal energy, and a second substrate having opposed first and second major surfaces. The second substrate is attached to the first substrate at the first major surface. The second major surface defines an isolation cell for enclosing a volume when the second substrate is attached to the support to thereby reduce the thermal mass of the microactuator and to thermally isolate the first substrate from the support.Type: GrantFiled: August 24, 1994Date of Patent: June 25, 1996Assignee: Hewlett-Packard CompanyInventors: Christopher C.

Patent number: 5110712Abstract: A system for integrating a composite dielectric layer in an integrated circuit to facilitate fabrication of a high density multi-level interconnect with external contacts. The composite dielectric layer comprises of a polymer layer which normally comprises a polyimide that is deposited using conventional spin-deposit techniques to form a planarized surface for deposition of an inorganic layer typically comprising silicon dioxide or silicon nitride. The inorganic layer is etched using standard photoresist techniques to form an inorganic mask for etching the polymer layer. A previously deposited inorganic layer functions as an etch stop to allow long over etches to achieve full external contacts which, in turn, allows high density interconnect systems on multiple levels.Type: GrantFiled: April 25, 1990Date of Patent: May 5, 1992Assignee: Hewlett-Packard CompanyInventors: Daniel D.

Patent number: 4925524Abstract: A method and system for forming tungsten structures in a semiconductor device which uses a chromium protective layer to protect underlying semiconductor layers during the etching process and a chromium mask layer so that tungsten structures can be formed with high aspect ratios using a reactive ion etching to etch the tungsten with a carbon tetrafluoride oxygen plasma in a reactive ion etcher. Long overetches can be achieved because of the high selectivity of chromium to the carbon tetrafluoride/oxygen plasma. The anisotropic nature of the reactive ion etcher prevents undercut during long overetches of the tungsten to further decrease losses in linewidth or increases in resistance as a result of overetching.Type: GrantFiled: January 4, 1989Date of Patent: May 15, 1990Assignee: Hewlett-Packard CompanyInventor: Christopher C.
