Hydrogen chlorideNdi mpweya wopanda mtundu wokhala ndi fungo loipa. Madzi ake otchedwa hydrochloric acid, omwe amadziwikanso kuti hydrochloric acid. Hydrogen chloride imasungunuka kwambiri m'madzi. Pa 0°C, voliyumu imodzi ya madzi imatha kusungunula mavoliyumu pafupifupi 500 a hydrogen chloride.

Ili ndi makhalidwe ndi zinthu zotsatirazi:

1. Kuyera kwambiri

Kuyera kwa kalasi yamagetsihydrogen chloridendi yokwera kwambiri, nthawi zambiri pa ppm kapena pamlingo wotsika, kuti zitsimikizire kuti palibe zodetsa zomwe zimalowetsedwa mu njira yopangira semiconductor.

2. Kusagwira ntchito bwino

Ndi mpweya wopanda mankhwala womwe sugwirizana ndi zinthu zina zambiri, zomwe ndizofunikira kwambiri popewa kuipitsidwa kwa zinthu ndi zida za semiconductor.

3. Kukhazikika kwakukulu

Giredi yamagetsihydrogen chloridenthawi zambiri imakhala ndi mankhwala okhazikika kuti iwonetsetse kuti zinthu zogwiritsidwa ntchito ndi semiconductor zimakonzedwa bwino.

Mu kukonza ma semiconductor, ntchito zazikulu za hydrogen chloride yamagetsi zimaphatikizapo:

1. Kuyeretsa ndi kukonza pamwamba

Monga chotsukira bwino pamwamba, kalasi yamagetsihydrogen chlorideimagwiritsidwa ntchito kuchotsa ma oxide ndi zinyalala pamwamba pa substrate kuti zitsimikizire ubwino ndi chiyero cha epitaxial layer kapena filimu.

2. Chithandizo cha kukula kwa Epitaxial

Pogwiritsidwa ntchito ngati chothandizira pakhungu pa epitaxial, zimathandiza kukonza bwino mawonekedwe a epitaxial layer, kukonza kufanana kwa lattice, komanso kuchepetsa mapangidwe a zolakwika za lattice.

3. Chithandizo cha substrate chisanachitike

Musanakonzekere zipangizo zamagetsi, kalasi yamagetsihydrogen chlorideingagwiritsidwe ntchito pokonza pamwamba pa substrate kuti pakhale maziko okhazikika kuti pakhale kulumikizana pakati pa epitaxial layer ndi substrate.

4. Wothandizira wochotsera

Mu ndondomeko ya chemical vapor deposition (CVD) kapena physical vapor deposition (PVD), electronic grade hydrogen chloride ingagwiritsidwe ntchito ngati njira yosamutsira mpweya kuti igwire nawo ntchito yoyika zinthu za semiconductor.

5. Wothandizira kusamutsa mpweya

Monga chothandizira kusamutsa mpweya, zinthu zina zoyambira mpweya zimalowetsedwa mu chipinda chochitirapo kanthu kuti zithandize kusintha kuchuluka kwa mpweya ndi kufanana kwa zinthuzo.

Makhalidwe amenewa amapanga kalasi yamagetsihydrogen chloridechothandizira chofunikira kwambiri pa ukadaulo wa semiconductor, chomwe chimakhudza kwambiri magwiridwe antchito ndi kudalirika kwa chipangizo chomaliza.

Kuwonjezera pa kugwiritsidwa ntchito kwake pokonza zinthu za semiconductor, hydrogen chloride yamagetsi imatha kupeza ntchito zosiyanasiyana m'magawo ena, kuphatikizapo: Kukonzekera zipangizo zoyera kwambiri, Ma cell amafuta, kukula kwa zinthu za semiconductor, Vapor Phase Lithography, Kusanthula Zinthu, ndi Kafukufuku wa Mankhwala.

Kawirikawiri, kalasi yamagetsihydrogen chloridendi mpweya wosiyanasiyana komanso woyera kwambiri womwe umagwiritsidwa ntchito m'njira zosiyanasiyana kunja kwa kupanga zinthu za semiconductor.
