ʻO ka wafer substrate 3'īniha 76.2mm 4H-Semi SiC Silicon Carbide Semi-insulting SiC wafers

Wehewehe Pōkole:

ʻO ka wafer SiC kristal hoʻokahi kiʻekiʻe (Silicon Carbide) no ka ʻoihana uila a me ka optoelectronic. ʻO ka wafer SiC 3 iniha kahi mea semiconductor hanauna hou, nā wafer silicon-carbide semi-insulating o 3-iniha ke anawaena. Ua manaʻo ʻia nā wafers no ka hana ʻana i nā mea mana, RF a me nā optoelectronics.

ʻO nā wafers substrate SiC (silicon carbide) semi-insulated 3-'īniha 4H kahi mea semiconductor i hoʻohana pinepine ʻia. Hōʻike ʻo 4H i kahi ʻano kristal tetrahexahedral. ʻO ke ʻano o ka semi-insulation he kiʻekiʻe nā ʻano kū'ē o ka substrate a hiki ke hoʻokaʻawale iki ʻia mai ke kahe o ke au.

Loaʻa i kēlā mau wafers substrate nā ʻano penei: conductivity thermal kiʻekiʻe, pohō conduction haʻahaʻa, kūpaʻa wela kiʻekiʻe maikaʻi loa, a me ke kūpaʻa mechanical a me ke kemika maikaʻi loa. No ka mea he ākea ka ikehu o ka silicon carbide a hiki ke kū i nā mahana kiʻekiʻe a me nā kūlana kahua uila kiʻekiʻe, hoʻohana nui ʻia nā wafers semi-insulated 4H-SiC i nā mea uila mana a me nā mea hana alapine lekiō (RF).

ʻO nā noi nui o nā wafers semi-insulated 4H-SiC:

1--Nā mea uila mana: Hiki ke hoʻohana ʻia nā wafers 4H-SiC e hana i nā mea hoʻololi mana e like me MOSFETs (Metal Oxide Semiconductor Field Effect Transistors), IGBTs (Insulated Gate Bipolar Transistors) a me Schottky diodes. ʻOi aku ka haʻahaʻa o ka pohō conduction a me ka hoʻololi ʻana o kēia mau mea hana i nā wahi voltage kiʻekiʻe a me nā mahana kiʻekiʻe a hāʻawi i ka pono a me ka hilinaʻi kiʻekiʻe.

2--Nā Mea Hana Alapine Lekiō (RF): Hiki ke hoʻohana ʻia nā wafers semi-insulated 4H-SiC e hana i nā mea hoʻonui mana RF kiʻekiʻe, alapine kiʻekiʻe, nā pale chip, nā kānana, a me nā mea hana ʻē aʻe. ʻOi aku ka maikaʻi o ka hana alapine kiʻekiʻe a me ke kūpaʻa wela o ka Silicon carbide ma muli o kona nui o ka electron saturation drift rate a me ke alakaʻi wela kiʻekiʻe.

3--Nā mea hana optoelectronic: Hiki ke hoʻohana ʻia nā wafers semi-insulated 4H-SiC e hana i nā diode laser mana kiʻekiʻe, nā mea ʻike kukui UV a me nā kaapuni hoʻohui optoelectronic.

Ma ke ʻano o ke kuhikuhi ʻana o ka mākeke, ke piʻi nei ke koi no nā wafers semi-insulated 4H-SiC me ka ulu ʻana o nā kahua uila mana, RF a me optoelectronics. ʻO kēia ma muli o ka nui o nā noi o ka silicon carbide, me ka pono o ka ikehu, nā kaʻa uila, ka ikehu hou a me nā kamaʻilio. I ka wā e hiki mai ana, ke hoʻohiki nui nei ka mākeke no nā wafers semi-insulated 4H-SiC a manaʻo ʻia e pani i nā mea silicon maʻamau i nā noi like ʻole.
