Muna 2018, musika wepasi rose wemagetsi gasi wemasekete akabatanidzwa wakasvika US $ 4.512 bhiriyoni, gore negore kuwedzera kwe16%. Kukura kwakanyanya kweiyo yemagetsi yakakosha gasi indasitiri yemasemiconductors uye yakakura musika saizi yakamhanyisa chirongwa chekutsiva chepamba chemagetsi akakosha gasi!
Chii chinonzi electron gas?
Electronic gasi inoreva iyo yakakosha sosi zvinhu zvinoshandiswa mukugadzirwa kwema semiconductors, flat panel kuratidza, mwenje-emitting diode, solar maseru uye zvimwe zvigadzirwa zvemagetsi, uye inoshandiswa zvakanyanya mukuchenesa, etching, firimu kugadzira, doping uye mamwe maitiro. Nzvimbo huru dzekushandisa gasi remagetsi dzinosanganisira indasitiri yemagetsi, masero ezuva, nharembozha, kufamba kwemota uye mota odhiyo nemavhidhiyo masisitimu, aerospace, indasitiri yemauto uye mamwe akawanda minda.
Gasi rakakosha remagetsi rinogona kukamurwa kuita zvikamu zvinomwe zvinoenderana nekemikari yayo: silicon, arsenic, phosphorus, boron, metal hydride, halide uye simbi alkoxide. Zvinoenderana neyakasiyana nzira dzekushandisa mumasekete akabatanidzwa, inogona kukamurwa kuita doping gasi, epitaxy gasi, ion implantation gasi, light-emitting diode gasi, etching gasi, kemikari vapor deposition gasi uye chiyero gasi. Kune anopfuura zana negumi magasi akakosha anoshandiswa muindasitiri yesemiconductor, ayo anopfuura makumi matatu anowanzoshandiswa.
Kazhinji, iyo semiconductor yekugadzira indasitiri inokamura magasi kuita marudzi maviri: akajairika magasi uye akakosha magasi. Pakati pavo, gasi rinowanzoshandiswa rinoreva nzvimbo yepakati uye inoshandisa gasi yakawanda, yakadai seN2, H2, O2, Ar, He, etc. Gasi rinokosha rinoreva mamwe magasi emakemikari anoshandiswa mukugadzirwa kwe semiconductor, se. kuwedzera, jekiseni reion, kusanganisa, kugeza, uye kuumbwa kwemasiki, iyo yatinoti magetsi chaiwo gasi, zvakadai sepamusoro-kuchena SiH4, PH3, AsH3, B2H6, N2O, NH3, SF6, NF3, CF4, BCl3, BF3, HCl, Cl2, nezvimwewo.
Mukuita kwese kwekugadzirwa kweiyo semiconductor indasitiri, kubva pakukura kwechip kusvika kune yekupedzisira mudziyo kurongedza, zvinenge zvese zvinongedzo hazviparadzaniswe kubva kune yemagetsi yakakosha gasi, uye akasiyana egasi rinoshandiswa uye zvemhando yepamusoro zvinodiwa, saka gasi remagetsi rine semiconductor zvinhu. "Chikafu".
Mumakore achangopfuura, zvinhu zvikuru zvemagetsi zveChina zvakaita semiconductors uye mapaneru ekuratidzira akawedzera mune hutsva hwekugadzira, uye pane kudiwa kwakasimba kwekupinza kunze kwemagetsi makemikari zvinhu. Nzvimbo yemagasi emagetsi muindasitiri yesemiconductor yave kuwedzera mukurumbira. Indasitiri yemagetsi gasi yemumba ichaunza kukurumidza kukura.
Electronic special gasi ine zvakanyanyisa zvinodiwa pakuchena, nekuti kana kuchena kusiri kusvika kune zvinodiwa, mapoka ekusachena akadai semhute yemvura uye okisijeni mumagetsi akakosha gasi anozogadzira nyore oxide firimu pamusoro peiyo semiconductor, iyo inokanganisa hupenyu hwesevhisi yemidziyo yemagetsi, uye iyo yemagetsi yakakosha gasi ine Zvimedu zvetsvina zvinogona kukonzera semiconductor mapfupi maseketi uye kukuvara kwedunhu. Zvinogona kutaurwa kuti kuvandudzwa kwekuchena kunoita basa rakakosha mugoho uye kuita kwekugadzira zvigadzirwa zvemagetsi.
Nekuenderera mberi kwekusimudzira kweindasitiri ye semiconductor, iyo chip yekugadzira dhizaini inoramba ichivandudza, uye ikozvino yasvika 5nm, iyo yave kuda kusvika kumuganhu weMutemo waMoore, wakaenzana nechikamu chemakumi maviri chehupamhi hwebvudzi remunhu. anenge 0.1 mm). Naizvozvo, izvi zvakare zvinoisa kumberi kwepamusoro zvinodiwa pakuchena kwemagetsi akakosha gasi anogadzirwa nemasemiconductors.
