  • Publication number: 20060136390
    Abstract: A computer-based system and method is provided which use multilevel hashing for lookup of a complex nested object (such as access control list) which has a plurality of nesting levels and each level has at least one element. Method stores representatives of a complex nested object in a data structure at locations determined by recursive multilevel hashing of the complex nested object elements. When needed, a match for an inputted complex nested object is determined by applying the same recursive multilevel hashing to the inputted complex nested object, as used during the storing of the complex nested object, and performing integer comparisons with hash values of the stored complex nested object.

  • Patent number: 6922890
    Abstract: A method is provided for planarization of structures which minimizes step heights, reduces process steps, improves cleanliness, and provides increased ease of debond. Structures are placed with working surfaces facing down onto an adhesive layer such that structures remain fixed during heating. A bi-layer encapsulating film is used to achieve planarization. A carrier is bi-laminated with a thermoplastic film layer followed by a chemically inert protective polymer film layer that can withstand etch and cleaning processes. The thermoplastic layer is laminated on top of the carrier; the polymer layer is laminated on top of the joined thermoplastic layer and carrier. The carrier with bi-layer film is then placed onto the backside of the structures to resist chemical attack from the front side during photostrip and enable planarization. When heat is applied, the bi-layer encapsulating film melts and pushes the polymer layer into the gaps between structures thereby achieving complete planarization.

  • Patent number: 6817086
    Abstract: A bilayer mask employed for lift off has a top strip which bridges between first and second bilayer portions and is completely undercut so that when one or more materials is sputter deposited the materials do not form fences abutting recessed edges of a bottom layer in undercuts below a top layer. Sacrificial protective layers are formed on a sensor and lead layers for protecting these components while overlapping portions of these materials on the top of the sensor formed during deposition can be removed by ion beam sputtering, after which the sacrificial protective layers can be removed by ion milling or reactive ion etching.
