Method for making carbon fibre-reinforced parts of composite material

The present invention relates to a method for making carbon fibre-reinforced parts of composite meterial. A coherent fiber preform made of carbon fibers presents holes formed from at least a first face of the preform, and the preform is densified by depositing therein a material constituting a matrix by means of a chemical vapor infiltration type process. The holes are formed by causing a plurality of non-rotary elongate tools to penetrate simultaneously, the tools being substantially mutually parallel and presenting on their surfaces roughnesses or portions in relief suitable for breaking and / or transferring fibers they encounter, the tools being caused to penetrate simultaneously by moving a support carrying the tools, and the tools being selected to have a cross-section that makes it possible to obtain in the carbon fiber preform holes that present a cross-section with a mean dimension lying in the range 50 mum to 500 mum.

A method of fabricating super junction mosfet with enhanced uis capability

The invention relates to a method for manufacturing a superjunction MOSFET with improved UIS capability. The method first forms a P-type column and a P-type body region on the epitaxial layer of the substrate, and implants high-dose P from the implantation window before forming the source region. Type impurity but no annealing operation, and then inject N type impurity according to the existing process method to form the source region; since the injection window is not laterally blocked by the isolation side wall before the source region is formed, it is conducive to the lateral diffusion of the high dose implanted P type impurity, The second implanted P-type impurity is pushed to the depth direction by means of the annealing operation during the formation of the source region, which increases the area distribution of the high-concentration P-type impurity, which is beneficial to reduce the base resistance of the BJT; in the source region and gate After the isolation sidewall of the pole sidewall is formed, a high dose of P-type impurity is implanted for the third time and annealed. The second and third implantation of P-type impurity increases the doping concentration of the base region, and can also make the base region The resistance is significantly reduced to achieve the purpose of improving the UIS capability of the device.
