Kvartsiputkia k\u00e4ytet\u00e4\u00e4n yleisesti puolijohdekiekkojen korkean l\u00e4mp\u00f6tilan diffuusiouunissa seostamiseen (kuten fosforin tai boorin diffuusio) tai hehkuttamiseen (seostusaineiden aktivointi).
Kantoaineen elinik\u00e4 on keskeinen parametri piikiekon laadun arvioinnissa. Jos kvartsiputken ep\u00e4puhtaudet (kuten metalli-ionit) saastuttavat kiekkoja, se voi johtaa kantoaineiden rekombinaation lis\u00e4\u00e4ntymiseen ja elinajan lyhenemiseen.
Testeiss\u00e4 mitataan v\u00e4hemmist\u00f6kantajien elinik\u00e4\u00e4, jotta voidaan arvioida prosessin vaikutusta kiekon s\u00e4hk\u00f6iseen suorituskykyyn.<\/p>\n\n\n\n

Kvartsiputkia k\u00e4ytet\u00e4\u00e4n CVD-reaktiokammioissa (Chemical Vapor Deposition). Jos putken sein\u00e4m\u00e4 likaantuu tai devitrifikaatio tapahtuu, epitaksikerroksen laatu voi heikenty\u00e4, jolloin kantoaineen elinik\u00e4 lyhenee.<\/p>\n\n\n\n

2. Aurinkokennojen testaus<\/h3>\n\n\n\n
Korkean hy\u00f6tysuhteen aurinkokennoprosesseissa, kuten PERC- ja TOPCon-prosessissa, kvartsiputkia k\u00e4ytet\u00e4\u00e4n passiivikerroksen (kuten SiNx tai Al\u2082O\u2083) laskeutumiseen tai korkean l\u00e4mp\u00f6tilan polttoon.
Kantajan elinik\u00e4 vaikuttaa suoraan kennon muuntotehokkuuteen. Jos kvartsiputki aiheuttaa ep\u00e4puhtauksia, kiekon pinnan rekombinaationopeus kasvaa.
Mittaukset suoritetaan k\u00e4ytt\u00e4m\u00e4ll\u00e4 QSSPC:t\u00e4 (Quasi-Steady-State Photoconductance) tai \u03bc-PCD:t\u00e4 (Microwave Photoconductance Decay) v\u00e4hemmist\u00f6kantajien elinajan m\u00e4\u00e4ritt\u00e4miseksi.<\/p>\n\n\n\n
\n\n\n\n3. Materiaalitutkimus (esim. laajakaistaiset puolijohteet).<\/h3>\n\n\n\n
Piikarbidi- (SiC) tai galliumnitridilaitteiden (GaN) korkean l\u00e4mp\u00f6tilan prosessit (>1500 \u00b0C) edellytt\u00e4v\u00e4t eritt\u00e4in puhtaita kvartsiputkia. Ep\u00e4puhtaudet voivat lis\u00e4t\u00e4 rajapinnan tilatiheytt\u00e4, mik\u00e4 johtaa kantoaineen elini\u00e4n lyhenemiseen.
Tutkimuksessa keskityt\u00e4\u00e4n usein epitaksikerrosten tai oksidikerrosten s\u00e4hk\u00f6isiin ominaisuuksiin.<\/p>\n\n\n\n
\n\n\n\n4. Muut asiaan liittyv\u00e4t testit<\/h3>\n\n\n\n
Kantoaineen k\u00e4ytt\u00f6ik\u00e4 vaikuttaa vastenopeuteen. Jos kvartsiputket saastuttavat herkki\u00e4 materiaaleja (kuten InGaAs), laitteen suorituskyky voi heikenty\u00e4.<\/p>\n\n\n\n
Jotkut asiakkaat saattavat yksinkertaisesti k\u00e4ytt\u00e4\u00e4 kvartsiputkia reaktioastioina testatakseen uusien materiaalien (kuten perovskiittien) kantoaineen dynamiikkaa.<\/p>\n\n\n\n
\n\n\n\nTestin merkityksellisyys<\/h3>\n\n\n\n
T\u00e4m\u00e4 parametri on kriittinen puolijohde- ja aurinkos\u00e4hk\u00f6aloilla, mutta tyypillisiss\u00e4 teollisissa tai kemiallisissa kokeissa sit\u00e4 ei yleens\u00e4 mitata erikseen.<\/p>\n\n\n\n
Yleisiss\u00e4 kemiallisissa kokeissa kvartsiputkien puhtausvaatimukset ovat suhteellisen alhaiset, kun taas puolijohde- ja aurinkos\u00e4hk\u00f6prosessit ovat eritt\u00e4in herkki\u00e4 kontaminaatiolle.<\/p>","protected":false},"excerpt":{"rendered":"
