Uburenganzira ni ubw'umwanditsi.Nyamuneka saba umwanditsi kugirango yemererwe gusubiramo ibicuruzwa, hanyuma utange inkomoko kubidasubirwaho.

Kuki insinga zikeneye uruhu rwa plastike?Ntushobora gukoresha insinga z'umuringa zambaye ubusa?Kuberako udafite uruhu rwa plastike rutandukanya, insinga irashobora gutwara amashanyarazi byoroshye mugihe ikora ku bindi bintu kandi ntishobora kwanduza umuyaga, cyangwa se niba ikomeye kandi ikagira amashanyarazi umuntu?Byagenda bite se niba insinga nyinshi zitayobora zigomba kuba zakozwe muri plastiki?Ntabwo aribyo rwose, insinga za mbere zapfunyitse imyenda, koza amavuta ya tung (na none, insinga zometseho), ahantu runaka, urebye ikiguzi, ubushobozi bwo gutandukanya amashanyarazi, nibindi, cyangwa niyo ubishaka, urashobora gukoresha silikoni , dioxyde ya silicon kugirango ikore wenyine, birumvikana ko ibyo byombi ari ibintu byoroshye cyane, bikwiriye gusa insinga zakozwe, ntizigera zigereranywa na terefone igendanwa, ibyo bikaba bikwiye gusa kuri chip imbere yimbere.

Ibyavuzwe haruguru birashoboka hamwe na silicon na dioxyde ya silicon yo kwigunga insinga za chip.Nibyo, kimwe mubikoreshwa cyane bya silicon substrate muri chips ni iyo kwigunga, kimwe no gukoresha uruhu rwa plastike kumigozi, gusa bikozwe muburyo butandukanye.Insinga zifite insinga z'umuringa zambaye ubusa mbere yo gusiga irangi uruhu rwa plastike;chip ifite uruhu rwoguhindura silicon mbere yuko rushyirwa (rushyizweho) hamwe ninsinga z'umuringa zambaye ubusa.

Kuki silikoni imwe ya kirisiti?Impamvu ebyiri, mbere ya byose, zigomba kuba zifite isuku cyane, bitabaye ibyo cyangwa bitabaye ibyo ntizizigirwa kubera abitabiriye amahugurwa kandi ntizatanga ibikoresho byabanjirije ibisekuruza bizakurikiraho.Ibi birumvikana rwose, sibyo?Urashaka gukora ihuriro rya PN ahantu runaka, ariko rero haribisanzwe hari atome za fosifore nkeya zanduye kuri kiriya kibanza kandi kimaze kuba imiterere ya N, none urashaka kuyihindura muburyo bwa P?Biroroshye kuva mubyera ukajya muburyo butandukanye, ariko biragoye cyane kuva mubyiciro bitandukanye ukajya mubyera, bityo ugatangirana na silicon-yera cyane.Kuki bidashobora kuba silikoni ya polyikristaline?Ifitanye isano nigisekuru cya PN ihuza (hashobora kuba hari ibindi bishushanyo, bihagarariwe na PN) kimwe.Ibi biterwa nuko ihuriro rya PN ari rito cyane kubikorwa bya intercalation hamwe nibisubizo biranga umuzunguruko, bisaba kubahiriza 100% ibisabwa mubishushanyo mbonera, bigenzurwa neza niba nta nenge zifite, umubare "umwanda" uvanze, niki amashanyarazi? ibiranga byabonetse.

Iyo hari inenge za lattice, ntabwo aribyo byanze bikunze.Inenge ya lattice muri polysilicon isa nu byobo biri mu rufatiro, kandi ni binini cyane, iyo rero asifalt ishyizwe, igisubizo cyamashanyarazi ntabwo kimeze nkahandi.Ihinduka 1!Iyi logique yumuzingi iracyafite ukuri?Mu kwagura, ibindi bikoresho birashobora gukoreshwa?Polycrystalline irashobora gukoreshwa?Mubindi bikorwa, cyangwa aho bitoroshye cyane (imbaraga zikomeye, logique idakomeye), birashoboka cyangwa birakorwaho iperereza.Kurugero, silikoni ikoporowe cyane muri ultra-high frequency, ultra-low voltage, ultra-high current situation, ntibikwiye cyane, noneho hariho nibindi bidasanzwe bya silicon germanium, gallium nibindi bikoresho byerekanwe, ndetse na substrate ya chip, imirasire y'izuba kuko icyingenzi nugutanga amashanyarazi akomeye, ntabwo uhangayikishijwe cyane no gutandukanya voltage gake cyane, birumvikana ko hari ikiguzi, inyinshi murizo ni silikoni polycristaline.Kubijyanye nibindi bikoresho, nyuma ya byose, silicon iri hose kandi igomba kwezwa gusa.Ibindi bintu, byombi bigoye kubibona, nabyo bigomba kwezwa.
