Epitaxial (EPI) Silicon Wafer

wehewehe

Epitaxial Silicon Wafera i ʻole EPI Silicon Wafer, he wafer o ka papa aniani semiconducting i waiho ʻia ma luna o ka ʻili aniani i poni ʻia o kahi substrate silikona e ka ulu epitaxial.ʻO ka papa epitaxial paha ka mea like me ka substrate e ka ulu ʻana o ka epitaxial homogeneous, a i ʻole kahi papa exotic me ka maikaʻi i makemake nui ʻia e ka ulu ʻana o ka epitaxial heterogeneous, kahi e hoʻohana ai i ka ʻenehana ulu epitaxial e komo pū me ka deposition chemical vapor deposition CVD, wai epitaxy LPE, a me ka molecular beam. epitaxy MBE e hoʻokō i ka maikaʻi kiʻekiʻe o ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka ʻili ʻili maikaʻi.Hoʻohana nui ʻia ʻo Silicon Epitaxial Wafers i ka hana ʻana i nā mea semiconductor holomua, nā mea semiconductor i hoʻohui ʻia i nā ICs, discrete a me nā mana mana, i hoʻohana ʻia no ka mea o ka diode a me ka transistor a i ʻole substrate no IC e like me ke ʻano bipolar, MOS a me nā mea BiCMOS.Eia kekahi, hoʻohana pinepine ʻia nā ʻāpana epitaxial a me nā kiʻiʻoniʻoni mānoanoa EPI silicon wafers i ka microelectronics, photonics a me nā noi photovoltaics.

Hāʻawi

Hiki ke hāʻawi ʻia nā Epitaxial Silicon Wafers a i ʻole EPI Silicon Wafer ma Western Minmetals (SC) Corporation i ka nui o 4, 5 a me 6 iniha (100mm, 125mm, 150mm anawaena), me ka orientation <100>, <111>, epilayer resistivity o <1ohm -cm a i ʻole 150ohm-cm, a me ka mānoanoa epilayer o <1um a i ʻole 150um, e hoʻokō i nā koi like ʻole i ka hoʻopau ʻana i ka ʻili o ka lāʻau i kālai ʻia a i ʻole LTO, i hoʻopaʻa ʻia i loko o ka cassette me ka pahu pahu ma waho, a i ʻole e like me ke ʻano kikoʻī i ka hopena kūpono. .
