A method of manufacturing a semiconductor device includes providing an apparatus (210, 510) having tabs (212, 214, 412, 414) for holding and separating semiconductor substrates wherein a first tab (212, 412) is different from a second tab (214, 414), using the first tab (212, 412) to support a semiconductor substrate (224) wherein the second tab (214, 414) does not support the semiconductor substrate (224), and exposing the semiconductor substrate (224) to a chemical to move the semiconductor substrate (224) towards the second tab (214, 414) without removing the semiconductor substrate (224) from the apparatus (210, 510).
摘要:
The present invention provides a charge storage device, comprising a pair of electrodes, each electrode being operable to store electric charge and having a respective capacitance CP, CN that is different to the other, with the ratio of the capacitances CP/CN being greater than 1. In exemplary embodiments, the charge storage device may be an asymmetrical supercapacitor, which is operable to provide an enhanced energy capacity by increasing the cell voltage through unequalising the electrode capacitance. Hence, by increasing the CP/CN ratio an improved power capability can be achieved over conventional devices, while offering a simple and low cost manufacturing strategy. The present invention has particular application with cameras, electric vehicles, elevators, renewable energy stores, fuel cells, batteries and many forms of electronic devices.

Two procedures are described that can be used to prepare polyhalogenated phenyl isocyanates (2,4,6-trichloro,2,3,5,6-tetrachloro, pentachloro, 2,4,6-tribromo and 2,4,6-trifluoro derivatives) from the corresponding anilines in good yields (95-99%) with small amounts of urea byproducts (1-5%) within reasonable reaction times (3-6 hours). These are:1. Liquid phase phosgenation of polyhalogenated anilines with tertiary amines as a hydrogen chloride acceptor.2. Liquid phase phosgenation of polyhalogenated anilines in excess phosgene at the beginning and throughout the reaction.

摘要:
This invention is a method for the protection of wood and other lignocellulosic materials from attack by micro-organisms with the use of iodates. The method consists of treating wood or other lignocellulosic material by soaking it in a solution of iodate for a period of time ranging from three hours to seven days at temperatures between 20.degree. C. and 50.degree. C. The treated material is then removed from the solution and dried. Wood treated with this method shows resistance to attack by wood-degrading micro-organisms. Furthermore, the iodates are resistant to leaching from the wood and other lignocellulosic materials after such treatment.
摘要:
A power transfer method and apparatus for efficient transfer of power are disclosed. Input power is converted in an essentially lossless manner to an intermediate form having a voltage or current in excess of that desired at the load. The intermediate power form is split into first and second parts, where the first part of the intermediate power form approximately matches an output power form desired at an output of the power transfer apparatus and the second part represents an excess power form. The first part of the intermediate power form is transferred to the output of the power transfer apparatus and the excess part is stored. Part or all of the stored excess energy is recycled in an essentially lossless manner, converted into a form that approximately matches the output power form desired at the output of the power transfer apparatus and transferred to the output of the power transfer apparatus.
