Vapor deposition of silicon dioxide nanolaminates

This invention relates to materials and processes for thin film deposition on solid substrates. Silica / alumina nanolaminates were deposited on heated substrates by the reaction of an aluminum-containing compound with a silanol. The nanolaminates have very uniform thickness and excellent step coverage in holes with aspect ratios over 40:1. The films are transparent and good electrical insulators. This invention also relates to materials and processes for producing improved porous dielectric materials used in the insulation of electrical conductors in microelectronic devices, particularly through materials and processes for producing semi-porous dielectric materials wherein surface porosity is significantly reduced or removed while internal porosity is preserved to maintain a desired low-k value for the overall dielectric material. The invention can also be used to selectively fill narrow trenches with low-k dielectric material while at the same time avoiding deposition of any dielectric on the surface area outside of the trenches.

Semiconductor device

A resin material having low dielectric constant is used as an inter-layer insulating film and its bottom surface is contacted with a silicon oxide film across the whole surface thereof. Thereby, the surface may be flattened and capacity produced between a thin film transistor and an pixel electrode may be reduced. Further, it allows to avoid a problem that impurity ions and moisture infiltrate into the lower surface of the resin material, thus degrading the reliability of whole semiconductor device.

Uniform dry etch in two stages

A method of etching silicon oxide from a multiple trenches is described which allows more homogeneous etch rates among trenches. The surfaces of the etched silicon oxide within the trench following the etch may also be smoother. The method includes two dry etch stages followed by a sublimation step. The first dry etch stage removes silicon oxide quickly and produces large solid residue granules. The second dry etch stage remove silicon oxide slowly and produces small solid residue granules in amongst the large solid residue granules. Both the small and large solid residue are removed in the ensuing sublimation step. There is no sublimation step between the two dry etch stages.

Method of laying panels

The present invention provides a method of laying and mechanically joining panels, especially floor panels. In a first step a first panel is already located in a first row. A second panel is positioned in a second row in a first position in relation to the first panel. A third panel is now brought into the second row and into the first position in relation to the first panel. In this position, there is a mutual distance between the adjacent edges of the second and third panel. In a second step the second and third panel are angled into the third mutual position in relation to the first panel. Thereby, the second and third panel each achieve the possibility of easy displacement in the third direction in relation to the first panel. In a third step one or both of the second and third panel are moved in relation to the first panel. By this displacement the second and third panel get in a second position in relation to each other. An additional intermediate step may be employed between the first and the second step. In this intermediate step the second and third panel are angled down into the second mutual position in relation to the first panel.

ActiveUS20070284255A1Stable cutting edgeReduce torsion fatiguePigmenting treatmentSurgeryWear resistantShape-memory alloy
A low friction top coat over a multilayer metal / ceramic bondcoat provides a conductive substrate, such as a rotary tool, with wear resistance and corrosion resistance. The top coat further provides low friction and anti-stickiness as well as high compressive stress. The high compressive stress provided by the top coat protects against degradation of the tool due to abrasion and torsional and cyclic fatigue. Substrate temperature is strictly controlled during the coating process to preserve the bulk properties of the substrate and the coating. The described coating process is particularly useful when applied to shape memory alloys.

The cutting edges are unequally spaced along the circumference of the end surface lying in a plane perpendicular to the longitudinal axis of rotation. In addition, all cutting edges are of a different helix from one another and the cutting edge geometries vary from one another to create a different sound pattern. This reduces resonant harmonic vibrations.

Nitric oxide-releasing polymers incorporating diazeniumdiolated silane derivatives

Biocompatible polymeric materials capable of providing in situ release of nitric oxide (NO) included diazeniumdiolated fumed silica as a filler in a multilayer polymer structure to release NO upon contact with water (blood). The blood-contacting polymer surface is preferably multi-layered so that the NO-releasing layer, containing the diazeniumdiolated fumed silica, is shielded from blood contact by one or more top (or base) coats. When in contact with blood, the NO released at the surface of the polymer prevents platelet activation and adhesion to the surface, thereby reducing platelet consumption, risk of thrombus formation and other clinical complications associated with interactions between blood and foreign materials.

Adhesives for vehicle body manufacturing

Two-component systems are described which are suitable for underlining, adhesive bonding of the crimped fold and sealing of auto body sections, particularly for crimped fold sealing of add-on vehicle parts. The two-component systems attain the requisite grip strength for mounting the add-on parts on the body as well as the requisite strength and dimensional stability for the production process up to and with the CIP passage, within the predetermined cycle time, on the basis of cross-linking of the sealant composition twice. In one embodiment, the surface of the two-component system is pre-cross-linked by a UV-induced reaction and by the cross-linking of the two-component system to the extent of portability. In addition, two-component systems are described which cross-link intentionally only partially up to a consistency that permits a rugged course of the process through cleaning baths and which harden completely only by means of a further hardening process, for instance in the CIP forced circulation oven.
