Firstly, the theory and knowledge of sparking and burning are briefly introduced. The holistic project of this experiment is designed aiming to the experiment motive. And then the micro-process technique on silicon is chosen. According to the technique, the structure and size of the micro chamber, the spark device, the gas-fired channels are designed. The mask of lithography is produced based on the design. At last, the whole burning room is produced by the techniques of photolithography, deposition, dry etching, wet etching, lift off, etc.
