Granted: 1987-02-11
Abstract: Elevated metal contact bumps are provided on a microelectronic semiconductor circuit, with the use of aluminum-palladium metallization as a base for selective electroless plating. The aluminum and palladium are preferably deposited sequentially in a single operation, i.e., without exposing the aluminum surface to the atmosphere. The aluminum-palladium film is then patterned in a single step, using an etchant which attacks both metals at substantially the same rate. The metal pattern is then covered with an insulation layer wherein apertures are opened to expose palladium at selected sites for immersion in an electroless plating bath of ionic Cu or Ni for bump formation.

Title: Non-woven fabric produced from randomly oriented card web
Inventor: MIGAKU SUZUKI
IPC: D04H/
Filed: 1982-03-09
Granted: 1987-01-28
Abstract: A random-laid fibrous web is consolidated into a fabric by jets of water directed through the web which is supported on a firm, non-permeable surface from which the jets rebound to increase the fibre entanglement. The web has a mass of 15-100 g/sq.m. It undergoes a preliminary consolidation by water jets whilst supported on a moving belt with a smooth, impermeable surface, then passes over a series of steel rollers against which subsequent rows of water jets are directed. The bore of the jet nozzles has a length-dia. ratio of less than 4-1, and the mean discharge of water across the width of the web is less than 40cc/sec/cm. The preliminary action gives the web sufficient intrinsic strength to be self-supporting without distorting as it passes between the subsequent sets of rollers. The process gives a three-dimensional interlacing of the fibres in the web, producing at high speed a high-quality fabric of uniform strength in all directions.
