A running model whose running ability changes in accordance with a given environment is caused to run on a field. The method allows an organic anti-reflecting coating film to be etched such that the etched film exhibits a side wall portion having a better shape as compared with that formed by a conventional technique. This PCD material is leached to remove the catalyst, forming a thermally stable product. By including a cache memory inside the loadstore unit, the processor is directly interfaced from its loadstore units to the caches. The resulting air mixture is then passed into the combustor.
