ʻO nā wafers SiC nā semiconductor i hana ʻia mai ka carbide silika.Ua hoʻomohala ʻia kēia mea i ka makahiki 1893 a he kūpono ia no nā ʻano hana like ʻole.ʻOi loa kūpono no nā diodes Schottky, nā diodes junction barrier Schottky, nā hoʻololi a me nā transistors metala-oxide-semiconductor field-effect.Ma muli o kona paʻakikī kiʻekiʻe, he koho maikaʻi loa ia no nā mea uila mana.
I kēia manawa, ʻelua ʻano nui o nā wafers SiC.ʻO ka mea mua he wafer i poni ʻia, ʻo ia ka wafer silika carbide hoʻokahi.Hana ʻia ia me nā kristal SiC maʻemaʻe kiʻekiʻe a hiki ke 100mm a i ʻole 150mm ke anawaena.Hoʻohana ʻia ia i nā mea uila mana kiʻekiʻe.ʻO ka lua o ka ʻano he epitaxial crystal silicon carbide wafer.Hana ʻia kēia ʻano wafer ma ka hoʻohui ʻana i hoʻokahi papa o nā kristal carbide silicon i ka ʻili.Pono kēia ʻano hana i ka mana pololei o ka mānoanoa o ka mea a ua ʻike ʻia ʻo N-type epitaxy.
ʻO ke ʻano aʻe he beta silicon carbide.Hana ʻia ka Beta SiC ma nā mahana ma luna o 1700 degere Celsius.ʻO ka alpha carbide ka mea maʻamau a loaʻa kahi ʻano aniani hexagonal e like me ka wurtzite.Ua like ke ʻano beta me ke daimana a hoʻohana ʻia i kekahi mau noi.ʻO ia ke koho mua loa no nā huahana semi-finished kaʻa uila.Ke hana nei kekahi mau mea hoʻolako wafer silicon carbide ʻaoʻao ʻekolu i kēia mea hou.
ʻO ZMSH SiC wafers nā mea semiconductor kaulana loa.He mea semiconductor kiʻekiʻe i kūpono no nā noi he nui.He mea pono loa ka ZMSH silicon carbide wafers no nā ʻano mea uila.Hāʻawi ʻo ZMSH i kahi ākea o nā wafers SiC kiʻekiʻe a me nā substrates.Loaʻa iā lākou ma nā ʻano N-type a semi-insulated.
2---Silicon Carbide: No ka wā hou o nā wafers
Nā waiwai kino a me nā hiʻohiʻona o ka carbide silika
Loaʻa i ka Silicon carbide kahi hana aniani kūikawā, me ka hoʻohana ʻana i kahi ʻano hexagonal kokoke i hoʻopaʻa ʻia e like me ke daimana.Hāʻawi kēia ʻano hana i ka silicon carbide e loaʻa i ka conductivity thermal maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe.Ke hoʻohālikelike ʻia me nā mea silika maʻamau, ʻoi aku ka nui o ka laula o ka carbide silicon, e hāʻawi ana i ka spacing band electron kiʻekiʻe, e hopena i ka neʻe electron kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.Eia kekahi, ʻoi aku ka kiʻekiʻe o ka carbide silicon i kahi kiʻekiʻe o ka electron saturation drift speed a me ka resistivity haʻahaʻa o ka mea ponoʻī, e hāʻawi ana i ka hana ʻoi aku ka maikaʻi no nā noi mana kiʻekiʻe.
Nā hihia noi a me nā manaʻo o nā wafers carbide silika
Nā polokalamu uila uila
Loaʻa i ka wafer Silicon carbide ka manaʻo ākea ākea i ke kahua uila uila.Ma muli o ko lākou mobility electron kiʻekiʻe a me ka conductivity thermal maikaʻi loa, hiki ke hoʻohana ʻia nā wafers SIC e hana i nā mea hoʻololi kiʻekiʻe kiʻekiʻe, e like me nā modula mana no nā kaʻa uila a me nā mea hoʻohuli lā.ʻO ke kūpaʻa wela kiʻekiʻe o nā wafers silicon carbide e hiki ai i kēia mau mea hana ke hana i nā wahi wela kiʻekiʻe, e hāʻawi ana i ka pono a me ka hilinaʻi.
Nā polokalamu optoelectronic
Ma ke kahua o nā mea optoelectronic, hōʻike nā wafers silicon carbide i ko lākou mau pono kūʻokoʻa.Loaʻa i nā mea carbide silikoni nā hiʻohiʻona ākea ākea, e hiki ai iā ia ke hoʻokō i ka ikehu photonon kiʻekiʻe a me ka nalowale māmā haʻahaʻa i nā mea optoelectronic.Hiki ke hoʻohana ʻia nā wafers silicone carbide e hoʻomākaukau i nā mea kamaʻilio kiʻekiʻe kiʻekiʻe, photodetectors a me nā lasers.ʻO kāna conductivity thermal maikaʻi loa a me ka haʻahaʻa defect crystal haʻahaʻa i kūpono no ka hoʻomākaukau ʻana i nā mea optoelectronic kiʻekiʻe.
Outlook
Me ka piʻi nui ʻana o ka noi no nā mea uila uila kiʻekiʻe, ʻo ka silicon carbide wafers ka wā e hiki mai ana ma ke ʻano he waiwai me nā waiwai maikaʻi loa a me ka hiki ke hoʻohana ākea.Me ka hoʻomau mau ʻana o ka ʻenehana hoʻomākaukau a me ka hōʻemi ʻana i ke kumukūʻai, e hoʻolaha ʻia ka noi kālepa o nā wafers silicon carbide.Manaʻo ʻia i nā makahiki e hiki mai ana, e komo mālie nā wafers silicon carbide i ka mākeke a lilo i koho nui no ka mana kiʻekiʻe, kiʻekiʻe kiʻekiʻe a me nā noi wela kiʻekiʻe.
3---Ka nānā ʻana i ka hohonu o ka mākeke wafer SiC a me nā ʻano ʻenehana
ʻO ka loiloi hohonu o nā mea hoʻokele wafer mākeke silicon carbide (SiC).
Hoʻopili ʻia ka ulu ʻana o ka mākeke wafer silicon carbide (SiC) e kekahi mau kumu nui, a he koʻikoʻi ka loiloi hohonu o ka hopena o kēia mau mea ma ka mākeke.Eia kekahi o nā mea hoʻokele mākeke koʻikoʻi:
Mālama i ka ikehu a me ka palekana o ke kaiapuni: ʻO ka hana kiʻekiʻe a me nā hiʻohiʻona haʻahaʻa haʻahaʻa o nā mea silicon carbide e kaulana ia i ke kahua o ka mālama ʻana i ka ikehu a me ka pale ʻana i ke kaiapuni.ʻO ke koi no nā kaʻa uila, nā mea hoʻololi o ka lā a me nā mea hoʻololi ikehu ʻē aʻe ke alakaʻi nei i ka ulu ʻana o ka mākeke o nā wafers silicon carbide no ka mea e kōkua ana i ka hōʻemi ʻana i ka ikehu.
Nā polokalamu uila uila: ʻoi aku ka maikaʻi o ka Silicon carbide i nā noi uila uila a hiki ke hoʻohana ʻia i ka uila uila ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā wahi wela kiʻekiʻe.Me ka hoʻolaha ʻana o ka ikehu hou a me ka hoʻolaha ʻana i ka hoʻololi ʻana i ka mana uila, ke hoʻomau nei ka koi no nā wafers silicon carbide i ka mākeke uila uila.
ʻO SiC wafers e hiki mai ana i ka hoʻomohala ʻenehana hana ʻenehana kikoʻī kikoʻī
ʻO ka hana nui a me ka hōʻemi ʻana i ke kumu kūʻai: ʻO ka hana ʻana o ka wafer SiC i ka wā e hiki mai ana e nānā hou aku i ka hana nui a me ka hoʻemi ʻana i ke kumukūʻai.Hoʻopili kēia i nā ʻenehana ulu i hoʻomaikaʻi ʻia e like me ka chemical vapor deposition (CVD) a me physical vapor deposition (PVD) e hoʻonui i ka huahana a hōʻemi i nā kumukūʻai hana.Eia kekahi, ʻo ka lawe ʻana i nā kaʻina hana naʻauao a me ka automated e manaʻo ʻia e hoʻomaikaʻi hou i ka pono.
ʻO ka nui a me ke ʻano o ka wafer hou: Hiki ke loli ka nui a me ke ʻano o nā wafers SiC i ka wā e hiki mai ana e hoʻokō i nā pono o nā noi like ʻole.Hiki i kēia ke hoʻokomo i nā wafers anawaena nui aʻe, nā ʻano like ʻole, a i ʻole nā wafers multilayer e hāʻawi i nā mea hiki ke hoʻolālā a me nā koho hana.
ʻO ka Energy Efficiency a me Green Manufacturing: ʻO ka hana ʻana i nā wafers SiC i ka wā e hiki mai ana e hoʻokau i ka manaʻo nui i ka pono o ka ikehu a me ka hana ʻōmaʻomaʻo.ʻO nā hale hana i hoʻohana ʻia e ka ikehu hou, nā mea ʻōmaʻomaʻo, ka hana ʻana i nā ʻōpala a me nā kaʻina hana haʻahaʻa-carbon e lilo i mau ʻano i ka hana ʻana.
