Kupukuta Pamwamba | SSP/DSP |
Diameter | 2inch/3inch/4inch/5inch/6inch |
Mtundu | P mtundu / N mtundu |
Kukhuthala kwa Oxidation Layer | 100nm ~ 1000nm |
Kuwongolera | <100> <111> |
Kulimbana ndi magetsi | 0.001-25000(Ω•cm) |
Kugwiritsa ntchito | Ntchito synchrotron radiation chitsanzo chonyamulira, PVD/CVD ❖ kuyanika monga gawo lapansi, magnetron sputtering kukula chitsanzo, XRD, SEM,Mphamvu ya atomiki, ma infrared spectroscopy, fluorescence spectroscopy ndi magawo ena oyesa kusanthula, magawo a maselo a epitaxial kukula, kusanthula kwa X-ray kwa ma crystalline semiconductors. |
Zophika za silicon oxide ndi mafilimu a silicon dioxide omwe amamera pamwamba pa zowotcha za silicon pogwiritsa ntchito mpweya wa okosijeni kapena nthunzi yamadzi pa kutentha kwakukulu (800 ° C ~ 1150 ° C) pogwiritsa ntchito njira yotenthetsera makutidwe ndi okosijeni yokhala ndi zida za chubu za ng'anjo ya mumlengalenga. makulidwe a ndondomeko ranges ku nanometers 50 kuti 2 microns, ndondomeko kutentha ndi madigiri 1100 Celsius, njira kukula anawagawa "chonyowa okosijeni" ndi "wouma mpweya" mitundu iwiri. Thermal Oxide ndi "wakula" wosanjikiza wa oxide, womwe uli ndi mawonekedwe apamwamba, kachulukidwe bwino komanso mphamvu ya dielectric kuposa CVD yoyika oxide zigawo, zomwe zimapangitsa kuti zikhale zapamwamba kwambiri.
Dry Oxygen Oxidation
Silikoni imachita ndi okosijeni ndipo wosanjikiza wa oxide umayenda mosalekeza kupita ku gawo lapansi. Dry oxidation iyenera kuchitidwa pa kutentha kuchokera ku 850 mpaka 1200 ° C, ndi kukula kochepa, ndipo ingagwiritsidwe ntchito pa kukula kwa chipata cha MOS. Dry oxidation imakonda kuposa kuthirira konyowa pakafunika kusanjikiza kwapamwamba kwambiri, kuonda kwambiri kwa silicon oxide. Dry makutidwe ndi okosijeni mphamvu: 15nm ~ 300nm.
2. Kunyowa oxidation
Njirayi imagwiritsa ntchito nthunzi yamadzi kuti ipange oxide wosanjikiza polowa mu chubu cha ng'anjo pansi pa kutentha kwakukulu. Kuchulukana kwa okosijeni wonyowa wa okosijeni ndikoyipa pang'ono kuposa okosijeni wowuma wa okosijeni, koma poyerekeza ndi okosijeni wowuma wa okosijeni ubwino wake ndikuti uli ndi kukula kwakukulu, koyenera kupitilira kukula kwa filimu ya 500nm. Kuchuluka kwa okosijeni wonyowa: 500nm ~ 2µm.
AEMD's atmospheric pressure oxidation ng'anjo chubu ndi chubu cha ng'anjo yaku Czech yopingasa, yomwe imadziwika ndi kukhazikika kwadongosolo, mawonekedwe abwino a filimu komanso kuwongolera tinthu tating'ono. Chubu cha ng'anjo ya silicon oxide chimatha kupanga zowotcha mpaka 50 pa chubu chilichonse, chokhala ndi mawonekedwe abwino kwambiri a intra- ndi inter-wafers.
