Pazinthu za semiconduct Warrintur youndana ndi njira zapamwamba zopitilira, pafupifupi mitundu 50 yamagesi omwe amafunikira. Magesi amagawidwa m'magulu ambiri komansoMpweya wapadera.

Kugwiritsa ntchito mipweya mu microectontics ndi semiconductoct makeke amagwiritsa ntchito mipweya nthawi zonse kumakhala gawo lofunikira mu semicoctor njira, makamaka semiconductor njira zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Kuchokera ku ULSI, TFT-LCD ku mafakitale apano-electromes (kuphatikizapo), kuphatikizapo zouma, oina, ion istation, enc.

Mwachitsanzo, anthu ambiri amadziwa kuti tchipisi amapangidwa ndi mchenga, koma poyang'ana njira yonse yopanga, zinthu zambiri zochulukitsa, zokutira zamadzimadzi, zopindika, mafuta apadera, ndi zinthu zofunika kwambiri. Kuthamangitsa kwam'mbuyo kumafunikiranso magawo, omasulira, mafelemu, zomangira, zida zomangira, etc. wa zinthu zosiyanasiyana. Magetsi apadera apadera ndi chinthu chachiwiri chachikulu kwambiri mu semicon sorses pambuyo pa silfer owopsa a silicon pambuyo pa masks ndi ojambula zithunzi.

Kuyera kwamafuta kumathandizira pazinthu zogwirira ntchito ndi zokolola zopangidwa, ndipo chitetezo cha magesi amagwirizana ndi thanzi la ogwira ntchito komanso chitetezo cha fakitale. Kodi kuyera kwa mafuta kumakhudza kwambiri bwanji njira ndi ogwira ntchito? Uku sikukokomeza, koma kumatsimikiziridwa ndi mawonekedwe owopsa a mafuta omwewo.

Gulu la mipweya wamba mu semiconduckiry

Mpweya wamba

Mafuta wamba amatchedwanso mafuta ambiri: kumatanthauza mpweya wa mafakitale wokhala ndi chiyero chofunikira chotsika kuposa 5n ndi kuchuluka kwakukulu ndi malonda. Itha kugawidwa kukhala mpweya wopatukana wa mpweya ndi mpweya wopangidwa malinga ndi njira zingapo zokonzekera. Haidrojeni (h2), nayitrogeni (N2), oxygen (o2), Argon (A2), etc.;

Mafuta apadera

Mafuta apadera amatanthauza mpweya womwe umagwiritsidwa ntchito m'minda yake ndipo ali ndi zofunikira zapadera zoyera, zosiyanasiyana, ndi katundu. KwenikweniSih4, Ph3, B2H6, A8H3,H000, CF4,Nh3, Pocl3, Sih2Cl2, Sihcl3,Nh3, Bcl3, Clk4, clf3, C2F6, N2O, F2, HF, HF,Sf6… ndi zina zotero.

Mitundu ya magesi opusa

Mitundu ya mipweya yapadera: kuwononga, poizoni, yoyaka, yoyaka, yoyaka, yoyaka, ndrt, etc.
Magulu omwe amagwiritsidwa ntchito kwambiri amagwiritsidwa ntchito ngati mitundu yosiyanasiyana:
(i) zowononga / zoopsa:H000, BF3, WF6, HBR, Sih2cl2, Nh3, CL2,Bcl3...
(ii) Kuyaka: H2,CH4,Sih4, Ph3, Ash3, Sih2Cl2, B2h6, Ch2f2, Ch3f, Ch ...
(iii) Zophatikizika: O2, CL2, N2o, NF3 ...
(iv) Irt: N2,Cf4, C2F6,C4F8,Sf6, CO2,Ne,Kr, Iye ...

Mukugwiritsa ntchito mitundu ya semiconductor kukupanga, mitundu 50 yosiyanasiyana ya mipweya yapadera (yotchedwa mipweya yapadera) imagwiritsidwa ntchito mu mafuta apadera) imagwiritsidwa ntchito poyamwa, kuphatikiza, kuphatikizika, njira zina, ndipo njira yonse imayendera mazana. Mwachitsanzo, Ph3 ndi Ash3 amagwiritsidwa ntchito ngati ma phosphorous ndi arpornic magwero a ion, omwe amagwiritsidwa ntchito poyambira njira.

Kuchokera pazinthu zomwe zili pamwambazi, titha kumvetsetsa kuti magesi ambiri semiconducts ndi ovulaza thupi la munthu. Makamaka, magesi ena, monga Sih4, akudziletsa. Malingana ngati akutulutsa, adzachita zachiwawa ndi mpweya mlengalenga ndikuyamba kutentha; ndipo Ash3 ndi woopsa kwambiri. Kutulutsa pang'ono kochepa kumatha kuvulaza miyoyo ya anthu, motero zofuna za chitetezo cha makina owongolera kuti mugwiritse ntchito mipweya yapadera ndiyokwera kwambiri.

Semiconductor imafuna mpweya wabwino kwambiri wokhala ndi "madigiri atatu"

Kuyera kwa mpweya

Zomwe zimapezeka mpweya wowoneka mu gasi nthawi zambiri zimafotokozedwa ngati gawo la kuyera kwa mpweya, monga 99.9990%. Nthawi zambiri, kufunikira kwa mpweya wamagetsi kumafika 5N-6n, ndipo kumafotokozedwanso ndi kuchuluka kwa kuchuluka kwa malo ophatikizika ppm (gawo lililonse), ndi PPILIS (gawo lililonse). Munda wamagetsi wa semiconduct uli ndi zofunikira kwambiri pakuyera komanso kukhazikika kwa mpweya wapadera, komanso kuyera kwa mpweya wa pakompyuta nthawi zambiri kumaposa 6n.

Kuuma

Zomwe zili m'madzi mu gasi, kapena kunyowa, nthawi zambiri zimafotokozedwa mu mame, monga mlengalenga dew, 10 ℃.

Kuyeletsa

Chiwerengero cha tinthu tating'onoting'ono mu gasi, tinthu tating'onoting'ono tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tomwe timafotokozeredwa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono a μm, tikufotokozedwa mu tinthu tating'onoting'ono tating'onoting'ono / m3. Kwa mpweya, nthawi zambiri zimafotokozedwa mu mg / m3 ya zotsalira zolimba, zomwe zimaphatikizapo mafuta.
