Abstract: PURPOSE: To simply etch an SiO 2  film on an Si substrate by forming on the film a layer of a high molecular material which generates double bonds therein when it is subjected to irradiation of an electron beam or X-rays, subjecting the layer of high molecular mateial to exposure treatment, and exposing the resulting layer to a hydrogen fluoride-containing gas.  
     CONSTITUTION: When an SiO 2  layer 12 formed on an Si substrate 11 is bored, the layer 12 is masked with a resist material consisting of a high molecular material 13, such as polydifluoroethylene which generates double bonds when it is subjected to irradiation of electron rays or X-rays. The masking film 13 is then subjected to exposure treatment in accordance with a predetermined pattern, and exposed to hydrogen fluoride-containing gas so as to etch that portion of the layer 12 which is under an exposed portion of the film 13 earlier than that portion of the layer 12 which is under an unexposed portion of the film 13. After a desired bore 14 has been obtained, the film 13 is removed. According to this method, the work efficiency can be much improved since the number of steps is far smaller than that of a photoresist method having a developing step, rinsing step and drying step.
