Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of molds, in particular to an electrode structure of a mold.
[ background of the invention ]
Electric spark machining is a new process for machining by utilizing electric energy and heat energy, and is commonly called as electric discharge machining. The difference between the electric discharge machining and the general cutting machining is that the metal material is gradually removed by the local and instantaneous high temperature generated by the pulse spark discharge generated between the tool and the workpiece, without the tool and the workpiece being in contact with each other.
When electric spark machining is carried out, the tool electrode and the workpiece are respectively connected with two poles of a pulse power supply and immersed in working liquid, or the working liquid is filled into a discharge gap. The feeding of the tool electrode to the workpiece is controlled by the automatic gap control system, and when the gap between the two electrodes reaches a certain distance, the pulse voltage applied to the two electrodes breaks down the working liquid to generate spark discharge. A large amount of heat energy is instantaneously concentrated in a discharge micro-channel, the temperature can reach more than ten thousand ℃, and the pressure is also changed rapidly, so that a local trace amount of metal material on the working surface is melted and gasified immediately, splashed into working liquid in an explosive mode, condensed rapidly, formed into solid metal particles and taken away by the working liquid. At this time, a tiny pit mark is left on the surface of the workpiece, the discharge is stopped for a short time, and the working fluid between the two electrodes is restored to an insulating state. Then, the next pulse voltage is broken down at another point where the two electrodes are relatively close to each other, so that spark discharge is generated, and the process is repeated. Thus, although the amount of metal to be removed by the pulse discharge is extremely small, a large amount of metal can be removed by the pulse discharge operation several thousands of times per second, and the productivity is high. The workpiece is continuously fed with the tool electrode while the metal of the workpiece is etched away under the condition that the discharge gap between the tool electrode and the workpiece is kept constant, and finally, the shape corresponding to the shape of the tool electrode is machined. Therefore, various complex profiles can be machined by changing the shape of the tool electrode and the relative motion mode between the tool electrode and the workpiece.
[ summary of the invention ]
