pulsed laser planarization of metal films for multilevel interconnects

multilevel interconnect schemes for integrated circuits generally require one or more planarization steps, in order to maintain an acceptably flat topography for lithography and thin-film step coverage on the higher levels. traditional approaches have involved planarization of the interlevel insulation (dielectric) layers, either by spin-..

development of a simple device for processing whole blood samples into measured aliquots of plasma

a capillary processor and aliquoter (cpa) has been designed and fabricated that is capable of accepting aliquots of whole blood and automatically processing them into discrete aliquots of plasma. the device consists of two disks, each of which contains 16 individual capillaries and a processing rotor. one of the disks accepts larger capil..

south korea: an export market profile. foreign agricultural economics rept

the united states exported $1.84 billion worth of agricultural products to south korea in 1983, making south korea the fifth leading market for u.s. agricultural products. price competition from chinese corn cut heavily into u.s. agricultural sales to south korea in 1984-85. u.s. exports will grow to around $2.3 billion (1983 dollars) by ..

alloy design criteria and evaluation methods for advanced austenitic alloys in steam service

design criteria and evaluation methods are identified for austenitic alloys that are needed for steam service at 650 sup 0 c and 35 mpa the design criteria are separated into five categories: metallurgical stability; fabrication and joining; mechanical properties; fireside corrosion resistance; and steamside corrosion resistance. in each ..

improvement of the corrosion resistance of turbine engine bearings final rept. aug 81-aug 85

improved bearing corrosion resistance can be achieved with either the use of a new corrosion resistant alloy, or by surface treating, or coating state-of-the-art m50 with a protective covering. this two-phase program investigated all three methods; alloys, coatings, and surface treatments. appropriate bearing materials, surface treatments..
