Iko kushandiswa kwakakura kwezvinhu zvinonangwa mumaprofesheni akasiyana siyana kunoita kuti kudiwa kwezvinhu zvinonangwa kuve kumusoro uye kumusoro. Zvinotevera Tichadaro suma muchidimbu iwe chii chinodiwa chekutanga chekushanda kwechinangwa, hoping kuti ndikubatsire.
Kuchena: Kuchena ndeimwe yezviratidzo zvekutanga zvinoshanda zvechinangwa, nekuti kuchena kwechinangwa kune simba guru pakushanda kwefirimu. Asi mukuita, kuchena kwezvinhu zvinotarirwa hakuna kufanana. Semuenzaniso, nekukura nekukurumidza kweiyo microelectronics profession, Saizi yesilicon wafer yakagadzirwa kubva pa6 ", 8" kusvika 12 ″, uye hupamhi hwewaya hwadzikira kubva 0.5um kusvika 0.25um,0.18um uye kunyange 0.13um. Kamwe 99.995% yekuchena kwechinangwa inogona kusangana nezvinodiwa zvetekinoroji zve0.35UMIC. Kugadzirira kwe0.18um mutsara kunoda 99.999% kana kunyange 99.9999% kuchena kwezvinhu zvinotarirwa.
Density: Kuti uderedze porosity muchinangwa chakasimba uye kuvandudza kushanda kwefirimu rekupfira, chinangwa chinowanzodiwa kuve nehupamhi hwepamusoro. The target density inokanganisa kwete chete sputtering rate asiwo magetsi uye optical maitiro emafirimu. Iyo yakakwirira iyo inotarirwa density, zviri nani basa remufirimu.Mukuwedzera, kuwanda uye simba rechinhu chakatarwa chakawedzerwa kuti chiite zvirinani kutsungirira kushushikana kwekupisa panguva yekupuruzira. Density zvakare imwe yeakakosha anoshanda zviratidzo zvezvinonangwa zvinhu.
Kusachena kwemukati: kusvibiswa mune chinangwa chakasimba uye okisijeni uye mhute yemvura mumapores ndiyo yekutanga kusvibiswa kwemafirimu akaunganidzwa.Zvinhu zvakasiyana-siyana zvakanangwa zvezvinangwa zvakasiyana zvine zvinodiwa zvakasiyana zvehutsvina hwakasiyana. Semuenzaniso, aruminiyamu yakachena uye aruminiyamu alloy zvinangwa zvinoshandiswa muindasitiri yesemiconductor zvine zvakakosha zvealkali simbi yemukati uye radioactive chinhu chemukati.
