156mm 159mm 6 iniha Sapphire Wafer no ka mea lawe C-Plane DSP TTV

ʻO ka wehewehe pōkole:

156mm/159mm anawaena, 6″ Al2O3 ʻaoʻao ʻelua ʻaoʻao poni (DSP) sapphire wafers me TTV ma lalo o 3 microns no nā papa lawe. 8″ / 6″ / 5″ / 2″ / 3″ / 4″ / 5″ C-axis, A-axis, R-axis, M-axis wafers. C-plane sapphire wafers a hiki i 6 iniha (6″/6 iniha) ke anawaena, me ka ʻaoʻao hoʻokahi ʻaoʻao polished (SSP) a i ʻole ʻaoʻao ʻelua polished (DSP), a me ka mānoanoa o 650 microns a i ʻole 1000 microns.

Hoʻomaʻemaʻe / Packaging	ʻO ka papa 100 ka hoʻomaʻemaʻe ʻana i ka lumi hoʻomaʻemaʻe a me ka ʻūpī ʻūhā,
	25 mau ʻāpana i hoʻokahi pahu cassette a i ʻole ʻāpana ʻāpana hoʻokahi.

ʻO ke ʻano Kylopoulos (KY method) ke hoʻohana ʻia nei e nā hui he nui ma Kina e hana i nā kristal sapphire no ka hoʻohana ʻana i nā ʻoihana uila a me nā optics.

Ma kēia kaʻina hana, hoʻoheheʻe ʻia ka alumini oxide kiʻekiʻe i loko o kahi pahu i nā mahana ma luna o 2100 degere Celsius. ʻO ka maʻamau, hana ʻia ka crucible me ka tungsten a i ʻole molybdenum. Hoʻokomo ʻia kahi aniani hua ʻano pololei i loko o ka alumina hehee. Huki mālie ʻia ke aniani hua i luna a hiki ke hoʻololi ʻia i ka manawa like. Ma ke kaohi pono ʻana i ka gradient wela, ka huki huki a me ka helu hoʻomaha, hiki ke hana ʻia kahi ingot nui, hoʻokahi-crystal, kokoke cylindrical ingot mai ka heheʻe.

Ma hope o ka ulu ʻana o nā ingots sapphire kristal hoʻokahi, wili ʻia lākou i loko o nā koʻokoʻo cylindrical, a laila ʻoki ʻia i ka mānoanoa pukaaniani i makemake ʻia a hoʻonani ʻia a hiki i ka hopena o ka ʻili i makemake ʻia.
