Abstract: Therefore, according to the present invention, a method is provided for depositing aluminum thin film layers to form improved quality contacts in a semiconductor integrated circuit device. All or some of the deposition process occurs at relatively low deposition rates at a temperature which allows improved surface migration of the deposited aluminum atoms. Aluminum deposited under these conditions tends to fill contact vias without the formation of voids. In order to improve the surface smoothness of the deposited aluminum, the deposition step is periodically interrupted.

Abstract: A data recording disk file of the liquid-bearing type has an improved head-disk interface provided in by a transducer carrier (100) with new properties. The carrier (100) supports a conventional head (109) for reading and writing data to the disk (130). The carrier has an air-bearing surface (110,112) near its front end, a ski pad (118) near its rear end, and a plurality of ski feet or struts (120,122) which support the air-bearing surface off the liquid film (146) of the disk when the disk file is not operating. The air-bearing surface is in the form of a pair of air-bearing rails (110,112) located outboard of the rear ski pad so that no air-bearing effect occurs in the rearward region of the carrier to assure the skiing action of the rear ski pad. As operational speed is approached the air-bearing lifts the struts off the disk and the rear ski pad is the sole ski foot on the liquid film. The rear ski pad has a convexly shaped leading edge which is wider than its trailing edge to minimize static friction and lubricant thinning during skiing, and the angle between the leading and trailing edges of the pad is selected to enable the pad to ski over the wide ranges of carrier-disk velocity which occur as the carrier moves from disk ID to OD.

Title: Improved copper-based metallizations for hybrid integrated circuits
Inventor: FRANKENTHAL ROBERT PETER
IPC: H01L23/522
Filed: 1993-10-20
Abstract: A new metallization is described which is a composite of subsequent metal layers beginning with a layer of titanium and having in an ascending order the following composition: Ti - TiPd - Cu - Ni - Au. TiPd is an alloy of titanium and palladium containing from 0.3 to 14 weight percent Pd, by the weight of the alloy. The TiPd alloy is etchable in an aqueous HF solution containing from 0.5 to 2.0 and higher, preferably from 0.5 to 1.2 weight percent HF. The use of the TiPd alloy avoids the occurrence of Pd residues remaining after the etching of Ti layer and lift-off (rejection etching) of Pd layer in a prior art Ti-Pd-Cu-Ni-Au metallization. Ti and TiPd layers are present in a thickness ranging from 100 to 300 nm and from 50 to 300 nm, respectively, and in a total minimum thickness needed to maintain bonding characteristics of the metallization. The metallization is suitable for use in various circuits including integrated circuits (ICs), hybrid integrated circuits (HICs), film integrated circuits (FICs), multi-chip modules (MCMs), etc.

Abstract: The process for producing out-of-alignment through-holes through substrate materials, in which the projections of the inlets and outlets do not coincide, is characterised, firstly, by etching windows being laid out in an offset manner on both sides and, secondly, by sufficiently strong undercutting of said windows. By laying out etching windows, which are displaced with respect to one another, on both sides of the substrate and by the substrate being etched through, through the windows laid out, "oblique" through-holes result in the substrate. It is also possible, solely by laying out the windows in an appropriate manner, to produce branched through-holes having more than one outlet. <IMAGE>

Title: Carbonyl sulphide fumigant and method of fumigation.
Inventor: BANKS HENRY JONATHAN
IPC: A01N59/04
Filed: 1993-01-15
Abstract: The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation properties comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorbtion by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly beneficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, or act as a source of such infestation.

Abstract: In the spraying of liquids, especially of small volumes, the ultrasound emitted by a piezoceramic is transmitted via a sealing medium into a housing part receiving the liquid to be sprayed. There, if the sealing material is arranged near the centre of emission, the ultrasound leads to a destruction of the housing part. If the sealing material is arranged further away, this leads, in the gap region then obtained, to an accumulation of liquid and bacteria. For this purpose, provision is made, according to the invention, for an elastic material (20) having gas inclusions to seal off an interspace (22) between the housing part (8) and the piezoceramic (16) against the liquid (10) to be sprayed. As a result of the elasticity of the material having gas inclusions, this brings about a sealing-off relative to the liquid to be sprayed. On account of the gas inclusions, an input of ultrasound into the housing part is avoided, because the ultrasound is reflected on the gas inclusions. Such ultrasonic sprays are suitable for the spraying of liquids, especially for the spraying of medicines and cosmetics. <IMAGE>
