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 pilina uila no ka hoʻohui ʻana i nā mea uila.
