Methods For Improved Encapsulation Of Thick Metal Features In Integrated Circuit Fabrication
US Patent:
6472307, Oct 29, 2002
Filed:
Jan 27, 2000
Appl. No.:
09/491644

Assignee:
Agere Systems Guardian Corp. - Orlando FL
International Classification:
H01L 21316
US Classification:
438624, 438639, 438702
Abstract:
The present invention provides a method of manufacturing an integrated circuit having a capping layer over a thick metal feature. In one embodiment, the method comprises forming first and second oxide layers over the thick metal feature, forming a composite oxide layer including an oxide spacer by etching the first and second oxide layers, and forming a capping layer over the composite oxide layer. More specifically, forming the first oxide layer involves using a high density plasma (HDP) process, forming the second oxide layer involves using a plasma enhanced chemical vapor deposition (PECVD) process, and forming the composite oxide layer preferably involves etching with a reactive ion etch.
Capacitor For A Semiconductor Device And Method For Fabrication Therefor

Assignee:
Agere Systems, Inc. - Allentown PA
International Classification:
H01L 27108
US Classification:
257301, 257303, 257306
Abstract:
A semiconductor device having a capacitor integrated in a damascene structure. In one embodiment, the capacitor is formed entirely within a metallization layer of a damascene structure, having therein a semiconductor device component. Preferably, the capacitor is formed within a trench, having been etched in the dielectric material of the metal layer and the capacitor includes a first capacitor electrode formed within the recess in electrical contact with the device component of the metallization layer. An insulator may be formed over the first capacitor electrode, with a second capacitor electrode formed over the insulator. These elements are preferably conformally deposited within the trench, thereby forming a recess, a portion of which extends within the trench. A subsequently fabricated device component may then be placed in electrical contact with the second capacitor electrode.
Use Of Cactus Mucilage As A Dispersant And Absorbant For Oil In Oil-Water Mixtures

US Classification:
210708
Abstract:
Despite advances in off-shore oil exploration and drilling technology, accidental oil spills do occur. Depending on their magnitude and location, irreparable damage may be inflicted on marine and coastal ecosystems. Emulsification of a water/surfactant /oil system results in the production of oil droplets and this depends on the formulation and composition variables, mixing characteristics and system preparation. Thus, research is ongoing on improving methods of cleaning up oil spills. Cactus mucilage was used to disperse and absorb oil from a simulated oil slick in different salt concentrations. Results show correlations between emulsion properties and interfacial characteristics of mucilage as function of aqueous phase salinity. Mucilage powder added to the oil floating on the water dispersed the oil film and absorbed the oil while remaining afloat, facilitates removal of the oil-mucilage aggregate. This invention is a competitive treatment for oil spill remediation with the added advantage of being more environmentally friendly.
