He aha ka wafer semiconductor?
ʻO ka wafer semiconductor kahi ʻāpana lahilahi a poepoe o nā mea semiconductor e lilo ana i kumu no ka hana ʻana i nā kaʻa hoʻohui (IC) a me nā mea uila ʻē aʻe. Hāʻawi ka wafer i kahi pālahalaha a me ke ʻano like ʻole kahi i kūkulu ʻia ai nā mea uila like ʻole.
ʻO ke kaʻina hana wafer he mau ʻanuʻu, ʻo ia hoʻi ka ulu ʻana i kahi aniani nui o ka mea semiconductor i makemake ʻia, ka ʻoki ʻana i ke aniani i loko o nā wafer lahilahi me ka ʻike daimana, a laila hoʻoliʻiliʻi a hoʻomaʻemaʻe i nā wafers e wehe i nā hemahema o ka ʻili a me nā haumia. ʻO ka hopena o nā wafers he ʻili palahalaha a maʻemaʻe, he mea koʻikoʻi ia no nā kaʻina hana ma hope.
Ke hoʻomākaukau ʻia nā wafers, hana lākou i nā kaʻina hana semiconductor, e like me ka photolithography, etching, deposition, a me doping, e hana i nā ʻano paʻakikī a me nā papa e pono ai ke kūkulu ʻana i nā mea uila. Hoʻohana pinepine ʻia kēia mau kaʻina hana ma ka wafer hoʻokahi e hana i nā kaʻa kaʻa i hoʻohui ʻia a i ʻole nā mea hana ʻē aʻe.
Ma hope o ka pau ʻana o ke kaʻina hana, hoʻokaʻawale ʻia nā ʻāpana pākahi ma ke kaomi ʻana i ka wafer ma nā laina i koho mua ʻia. Hoʻopili ʻia nā ʻāpana i hoʻokaʻawale ʻia e pale iā lākou a hāʻawi i nā pili uila no ka hoʻohui ʻana i nā mea uila.
Nā mea like ʻole ma ka wafer
Hana mua ʻia nā wafers Semiconductor mai ka silika-crystal hoʻokahi ma muli o kona nui, nā waiwai uila maikaʻi loa, a me ka launa pū me nā kaʻina hana semiconductor maʻamau. Eia nō naʻe, ma muli o nā noi kikoʻī a me nā koi, hiki ke hoʻohana ʻia nā mea ʻē aʻe e hana i nā wafers. Eia kekahi mau laʻana:
ʻO Silicon carbide (SiC) kahi mea semiconductor bandgap ākea e hāʻawi ana i nā waiwai kino maikaʻi i hoʻohālikelike ʻia i nā mea kuʻuna. Kōkua ia i ka hōʻemi ʻana i ka nui a me ke kaumaha o nā mea hana discrete, modules, a me nā ʻōnaehana holoʻokoʻa, ʻoiai e hoʻomaikaʻi ana i ka pono.
Nā ʻano nui o SiC:
- -Wide Bandgap:ʻEkolu mau manawa ko ka bandgap o SiC ma mua o ke kilika, hiki iā ia ke hana ma nā mahana kiʻekiʻe, a hiki i 400°C.
- -Kiʻekiʻe Critical Breakdown Field:Hiki iā SiC ke kūpaʻa a hiki i ka ʻumi manawa o ke kahua uila o ke silika, e kūpono ana ia no nā mea uila kiʻekiʻe.
- -Kiʻekiʻe Thermal Conductivity:Hoʻopau maikaʻi ʻo SiC i ka wela, kōkua i nā mea hana e mālama i nā mahana hana maikaʻi loa a hoʻolōʻihi i ko lākou ola.
- -Ka holo kiʻekiʻe Saturation Electron Drift Velocity:Me ka papalua o ka drift velocity o ke silika, hiki i ka SiC ke hoʻololi i nā alapine hoʻololi kiʻekiʻe, e kōkua ana i ka miniaturization mīkini.
Nā noi:
-
-Ka uila uila:ʻOi aku ka maikaʻi o nā mea mana SiC i nā kaiapuni kiʻekiʻe-voltage, kiʻekiʻe o kēia manawa, kiʻekiʻe-mehana a me nā alapine kiʻekiʻe, e hoʻonui nui ana i ka hoʻololi ʻana i ka ikehu. Hoʻohana nui ʻia lākou i nā kaʻa uila, nā keʻena hoʻoili, nā ʻōnaehana photovoltaic, ka halihali kaʻaahi, a me nā grids akamai.

- Nā Kūkākūkā Microwave:He mea koʻikoʻi nā polokalamu GaN RF e pili ana i ka SiC no ka ʻenehana kamaʻilio kelepona, ʻoi aku hoʻi no nā kahua kahua 5G. Hoʻohui kēia mau mea hana i ka conductivity thermal maikaʻi loa o SiC me ka hopena RF kiʻekiʻe, mana kiʻekiʻe o GaN, e hoʻolilo iā lākou i koho koho no nā hanauna kelepona kelepona kiʻekiʻe.
Gallium nitride (GaN)ʻO ia ke kolu o ka hanauna ākea bandgap semiconductor me kahi bandgap nui, kiʻekiʻe thermal conductivity, kiʻekiʻe electron saturation drift velocity, a me nā hiʻohiʻona maikaʻi loa. Loaʻa i nā polokalamu GaN nā manaʻo noiʻi ākea ma nā wahi kiʻekiʻe, ka wikiwiki, a me ka mana kiʻekiʻe e like me ke kukui mālama ola LED, nā hōʻike projection laser, nā kaʻa uila, nā grids akamai, a me nā kamaʻilio 5G.
Gallium arsenide (GaAs)he mea semiconductor i ʻike ʻia no kona alapine kiʻekiʻe, ka mobility electron kiʻekiʻe, ka mana kiʻekiʻe, ka leo haʻahaʻa, a me ka linearity maikaʻi. Hoʻohana nui ia i nā ʻoihana optoelectronics a me nā microelectronics. I nā optoelectronics, hoʻohana ʻia nā substrates GaAs e hana i nā LED (light-emitting diodes), LD (laser diodes), a me nā mea photovoltaic. I ka microelectronics, hoʻohana ʻia lākou i ka hana ʻana o MESFET (metal-semiconductor field-effect transistors), HEMT (high electron mobility transistors), HBTs (heterojunction bipolar transistors), ICs (integrated circuits), microwave diodes, a me nā mea hana Hall effect.
Indium phosphide (InP)ʻO ia kekahi o nā mea koʻikoʻi III-V pūhui semiconductor, i ʻike ʻia no ka neʻe ʻana o ka electron kiʻekiʻe, ka pale ʻana i ka radiation maikaʻi, a me ka bandgap ākea. Hoʻohana nui ʻia ia i nā ʻoihana optoelectronics a me microelectronics.
