The scientist of the IBM academy that is located in Su Li world has developed a kind of new technology, can give miniature structure with treatment of bougie of a silicon. Length of bougie of this kind of silicon is 500 accept rice, the acuteness that a dimension is rice of a few accept only is pinpoint -- the pencil that nibbed than is 100 thousand times smaller. The metric system of IBM academy pay builds the manager Michel Despont of the group to say, this kind of technique can be machined piece small the tiny design to 15 accept rice and structure, "Now, we get the limitation of pinpoint diameter. Give smaller size for treatment, what should do exclusively is a design it is better to go out pinpoint. " Despont points out, technology of purify of this kind of material will conduce to the miniature object that waits for a domain to develop dimension to amount to accept rice class in science of technology of electron, chip, medical treatment, life and photoelectricity technology. Bougie of this kind of silicon adheres to it is OK to be in on bent cantilever, this cantilever can be machined with the precision scanning of 1 accept rice base material. Despont says, "Bougie and cantilever are become with as same as production microelectronics chip honest legal system. Nevertheless, give the taper of bougie for treatment, we used a kind of special technology, through etching material, formed the structure of similar taper. Through heat and using power, silicon bougie is OK the design purify base material according to predefine. Accordingly, its treatment means resembles " Na Mixi is cut " machine tool, just it won't arise cut bits, use force and heat to make material evaporates however. Resemble groovy milling same, through adjusting cutting force, or repeat the feature with specific treatment, can with base material of more of purify of accept rice precision. Despont says, "Normally, the cutting force limits that we bring to bear on is 10 - 100 accept Newton. The temperature that cantilever carries is normally 500 - 700 ℃ . Bougie and the temperature that protect office of stratum boundary face are the in part that temperature produces on cantilever normally, it makes bougie enough resists the influence that evaporate fit uses. " this kind of Namijia is versed in another advantage of the technology is, produce a picture that machines a structure through using identical probe, can undertake assessment to sample directly. And a few otherer treatment method (if electron beam cuts corrode treatment) cannot accomplish this. Despont says, when using the treatment that engrave corrode, "You can have a test beforehand, how much is the treatment parameter that knows oneself, but you cannot carry out control to craft however in machining a process, you must when after treatment ends, ability knows whether treatment result is appropriate. " Despont thinks, this kind of Namijia is versed in the technology may be commercialized in the implementation inside two years. This research group is searching manufacturer of a tool, put the use licence of this technology that develops by IBM with Xiang Jifa. CNC Milling
