Ngo-2018, imarike yegesi ye-elektroniki yehlabathi yeesekethe ezidibeneyo ifikelele kwi-US $ 4.512 yebhiliyoni, ukunyuka konyaka-ngonyaka nge-16%. Izinga eliphezulu lokukhula kweshishini legesi ekhethekileyo yombane yee-semiconductors kunye nobukhulu bemarike enkulu ikhawulezise isicwangciso sasekhaya sokutshintshwa kwegesi ekhethekileyo yombane!
Yintoni igesi ye-electron?
Igesi ye-elektroniki ibhekiselele kwizinto ezisisiseko zomthombo ezisetyenziselwa ukuveliswa kwee-semiconductors, imiboniso yepaneli ecaba, i-diode ekhupha ukukhanya, iiseli zelanga kunye nezinye iimveliso ze-elektroniki, kwaye isetyenziswa ngokubanzi ekucoceni, e-etching, ekubunjweni kwefilimu, i-doping kunye nezinye iinkqubo. Imimandla ephambili yesicelo segesi ye-elektroniki ibandakanya imboni yombane, iiseli zelanga, unxibelelwano lweselula, ukuhamba kweemoto kunye neenkqubo zomsindo wemoto kunye nevidiyo, i-aerospace, imboni yezempi kunye nezinye iinkalo ezininzi.
Igesi ekhethekileyo ye-elektroniki inokwahlulwa ngokweendidi ezisixhenxe ngokwemichiza yayo: i-silicon, i-arsenic, i-phosphorus, i-boron, i-hydride yensimbi, i-halide kunye ne-allkoxide yensimbi. Ngokweendlela ezahlukeneyo zokusetyenziswa kwiisekethe ezidibeneyo, inokwahlulwa ibe yi-doping gas, i-epitaxy gas, i-ion implantation gas, i-light-emitting diode gas, i-etching gas, i-chemical vapor deposition gas kunye ne-balance gas. Kukho ngaphezu kwe-110 iyunithi yeegesi ezizodwa ezisetyenziswa kwishishini le-semiconductor, apho ngaphezu kwe-30 isetyenziswa ngokuqhelekileyo.
Ngokuqhelekileyo, ishishini lokuvelisa i-semiconductor lihlula iigesi zibe ziintlobo ezimbini: iigesi eziqhelekileyo kunye neegesi ezikhethekileyo. Phakathi kwabo, igesi esetyenziswa ngokuqhelekileyo ibhekisela kwi-centralized supply kwaye isebenzisa igesi eninzi, njenge-N2, i-H2, i-O2, i-Ar, i-He, njl. ulwandiso, inaliti ye-ion, ukudibanisa, ukuhlamba, kunye nokwakheka kwemaski, nto leyo ngoku esiyibiza ngokuba yigesi ekhethekileyo ye-elektroniki, efana ne-high-purity SiH4, PH3, ASH3, B2H6, N2O, NH3, SF6, NF3, CF4, BCl3, BF3, HCl, Cl2, njl.
Kuyo yonke inkqubo yemveliso yeshishini le-semiconductor, ukusuka ekukhuleni kwe-chip ukuya kwi-package yokugqibela yesixhobo, phantse yonke ikhonkco ayinakwahlulwa kwigesi ekhethekileyo ye-elektroniki, kunye neentlobo zegesi ezisetyenzisiweyo kunye neemfuno ezikumgangatho ophezulu, ngoko ke igesi ye-elektroniki inezixhobo ze-semiconductor. "Ukutya".
Kwiminyaka yakutshanje, amacandelo amakhulu e-elektroniki e-China afana ne-semiconductors kunye neepaneli zokubonisa ziye zanda kumthamo omtsha wemveliso, kwaye kukho imfuno emandla yokutshintshwa kwezinto ze-elektroniki zemichiza. Isikhundla segesi ye-elektroniki kwishishini le-semiconductor iye yanda kakhulu. Ishishini lasekhaya legesi ye-elektroniki liya kuzisa ukukhula okukhawulezayo.
Igesi ekhethekileyo ye-elektroniki ineemfuno eziphezulu kakhulu zokucoceka, kuba ukuba ubunyulu abukho kwiimfuno, amaqela angcolileyo anjengomphunga wamanzi kunye neoksijini kwigesi ekhethekileyo ye-elektroniki iya kwenza ngokulula ifilimu ye-oxide kumphezulu we-semiconductor, echaphazela i-oxygen film. ubomi benkonzo yezixhobo zombane, kunye negesi ekhethekileyo yombane iqulethe Amasuntswana okungcola anokubangela iisekethe ezimfutshane ze-semiconductor kunye nomonakalo wesekethe. Kunokuthiwa ukuphuculwa kobunyulu kudlala indima ebalulekileyo kwisivuno kunye nokusebenza kwemveliso yesixhobo sombane.
Ngophuhliso oluqhubekayo lweshishini le-semiconductor, inkqubo yokuvelisa i-chip iyaqhubeka nokuphucula, kwaye ngoku ifikelele kwi-5nm, esele isondele kumda woMthetho kaMoore, olingana neshumi elinesibini lobubanzi beenwele zomntu. malunga ne-0.1 mm). Ke ngoko, oku kubeka phambili iimfuno eziphezulu kubunyulu begesi ekhethekileyo ye-elektroniki eveliswa zii-semiconductors.
