N'izu a, Yunboshi nyere ụfọdụ igwe anaghị agba nchara akọrọ maka ụlọ ọrụ SMT(semiconductor arịọnụ technology). Dị ka onye na-eduga nkwakọ ngwaahịa mgbawa na ụlọ ọrụ nnwale, ngwaahịa ha na-asọmpi ma mara mma na ụlọ ọrụ semiconductor. Otú ọ dị, n'ihi ụfọdụ ihe ịma aka na nsogbu na nchekwa wafer, wafers ndị ha na-emepụta nwere nnukwu ihe a chọrọ maka ebe nchekwa. Mgbanwe ọ bụla dị ntakịrị nwere ike imebi wafers, na wafers na-adị mfe oxidized na mmetọ. Ya mere, a ga-echekwa ha na ebe ikuku oxygen na-adịghị na uzuzu. Igwe igwe anaghị agba nchara maka ụlọ ọrụ SMT. Yunboshi na-enye njikwa okpomọkụ na iru mmiri dị irè yana ngwọta mgbochi oxidation maka kabinet nitrogen. Ụlọ ọrụ nitrogen na-echebe ndị wafer site na oxidation na mmetọ site n'inye ikuku oxygen na ebe nchekwa na-enweghị uzuzu, na-eme ka nkwụsi ike na ntụkwasị obi nke wafers n'oge nchekwa.
