    摘要: An apparatus of the invention has a closable chamber that can be sealed and is capable of withstanding an increased pressure and high temperature. The chamber contains a substrate holder that can be rotated around a vertical axis, and an edge-grip mechanism inside the substrate holder. The deposition chamber has several inlet ports for the supply of various process liquids, such as deposition solutions, DI water for rinsing, etc., and a port for the supply of a gas under pressure. The apparatus is also provided with reservoirs and tanks for processing liquids and gases, as well as with a solution heater and a control system for controlling temperature and pressure in the chamber. The heater can be located outside the working chamber or built into the substrate holder, or both heaters can be used simultaneously. Uniform deposition is achieved by carrying out the deposition process under pressure and under temperature slightly below the boiling point of the solution. The solution can be supplied from above via a shower head formed in the cover, or through the bottom of the chamber. Rinsing or other auxiliary solutions are supplied via a radially moveable chemical dispensing arm that can be arranged above the substrate parallel thereto.

    摘要: The present invention relates to compositions and a method for electroless formation of alkaline-metal-free coatings on the basis of cobalt and composition of cobalt with tungsten and phosphorus, which have high resistance to oxidation and stability of electrical characteristics, when the Co—Cu system layer is used in IC chips. The composition of the electroless solution contains more than one reducing agents, one of which can catalyze the initial electroless deposition layer of cobalt on copper (called initiator), while the other maintains deposition of cobalt on the aforementioned initial layer as the process is continued. Small amount (100-5000 ppm) of elements from the initiator also builds into the electroless film, which is expected to further improve the barrier properties of the resultant film compared to the deposition bath without initiator. Such coating may find application in semiconductor manufacturing where properties of deposited films and controllability of the composition and physical and chemical characteristics of the deposited films may be critically important.

    摘要: A method for the amplification of a target nucleic acid is disclosed comprising the steps of reacting a nucleic acid with an amplification reaction mixture and a modified thermostable enzyme, wherein said modified thermostable polymerase is prepared by a reaction of a mixture of a thermostable polymerase and a chemical modifying reagent. The chemical modification reagent is an aldehyde, preferably formaldehyde. Essentially complete inactivation of the enzyme at ambient temperatures is achieved, with recovery of enzymatic activity at temperatures above 50° C.

    摘要: A computer-implemented error detection mechanism for detecting programming errors in a computer program. The computer-implemented error detection method described herein can make use of a Function Behavior Knowledge Base (FBKB) to approximate how a virtual function changes state of the program execution for all methods that can be called at each specific invocation point. The FBKB is used to select what implementation of a virtual function should be called in order to give rise to a programming defect. By dropping implementations that do not lead to a programming defect, the set of possible object runtime types is reduced. If this set is empty by the end of the analysis, then a defect is not possible, otherwise the set of object runtime types will contain types that may cause a defect.
