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.

Two special structural features of the sulfonium salt were proved to stabilize its corresponding ylide and depress the 2,3-sigma rearrangement. One is that there is a trimethylsilyl in the end of the allylic double band. This silicon atom can stabilize a α-carbon anion and the corresponding ylide. Another is that there is hydroxy group in the beta-position of sulfonium atom. The oxygen of this hydroxy group may stabilize the sulfonium cation.
