Site na mmepe nke teknụzụ semiconductor na-aga n'ihu, na ụlọ ọrụ semiconductor na ọbụna ụlọ ọrụ fotovoltaic, ihe ndị a chọrọ maka ịdị elu nke mkpụrụ osisi wafer ma ọ bụ mpempe akwụkwọ epitaxial dịkwa oke siri ike. Yabụ, kedu ihe dị mma achọrọ maka wafers? Na-eweresapphire efereDị ka ọmụmaatụ, kedu ihe ngosi enwere ike iji nyochaa ogo elu nke wafers?
Kedu ihe nrịbama nyocha wafers?
Ihe ngosi atọ ahụ
Maka sapphire wafers, ihe nleba anya ya bụ ngụkọta ọkpụrụkpụ deviation (TTV), bend (Bow) na Warp (Warp). Paragraf atọ ndị a ọnụ na-egosipụta ịdị larịị na oke ịdị n'otu nke wafer silicon, ma nwee ike tụọ ogo nke wafer. Enwere ike ijikọ corrugation na larịị iji nyochaa ịdị mma nke elu wafer.
Kedu ihe bụ TTV, BOW, Warp?
TTV (Mkpokọta Ọdịiche ịdị arọ)
TTV bụ ọdịiche dị n'etiti oke na kacha nta nke wafer. Oke a bụ ihe ndeksi dị mkpa eji elele nha nha wafer. N'ime usoro semiconductor, ọkpụrụkpụ nke wafer ahụ ga-abụrịrị otu n'elu elu dum. A na-emekarị nha na ebe ise na wafer ma gbakọọ ọdịiche ahụ. N'ikpeazụ, uru a bụ ihe ndabere dị mkpa maka ikpebi àgwà nke wafer.
Ụta
Ụta n'ichepụta semiconductor na-ezo aka n'ehulata nke wafer, na-ahapụ ohere dị n'etiti etiti nke wafer na-enweghị ihe mgbochi na ụgbọ elu ntụaka. Ma eleghị anya, okwu ahụ sitere na nkọwa nke ọdịdị nke ihe mgbe ọ na-ehulata, dị ka ụta gbagọrọ agbagọ. A kọwapụtara uru ụta site n'ịtụ ọdịiche dị n'etiti etiti na nsọtụ nke wafer silicon. A na-egosipụtakarị uru a na micrometers (µm).
Warp
Warp bụ akụrụngwa zuru ụwa ọnụ nke wafer na-atụ ọdịiche dị n'etiti oke kacha na anya kacha nta n'etiti etiti wafer na-enweghị ihe mgbochi na ụgbọ elu ntụaka. Na-anọchi anya anya site na elu nke silicon wafer na ụgbọ elu.
Kedu ihe dị iche n'etiti TTV, Bow, Warp?
TTV na-elekwasị anya na mgbanwe n'ịdị arọ na ọ dịghị echegbu onwe ya na mgbagha ma ọ bụ mgbagha nke wafer.
Ụta na-elekwasị anya n'ozuzu ehulata, tumadi na-atụle agbagọ nke etiti ebe na nsọtụ.
Warp dị nkenke karịa, gụnyere ịgbagọ na ntụgharị nke elu wafer dum.
Ọ bụ ezie na akụkụ atọ ndị a metụtara ọdịdị na njirimara geometric nke silicon wafer, a na-atụ ha ma kọwaa ya dị iche iche, mmetụta ha na usoro semiconductor na nhazi wafer dịkwa iche.
Obere ihe atọ ahụ, nke ka mma, na nnukwu oke, na-enwe mmetụta na-adịghị mma na usoro semiconductor. Ya mere, dị ka a semiconductor practitioner, anyị ga-aghọta mkpa nke wafer profaịlụ parameters maka dum usoro, na-eme semiconductor usoro, ga-aṅa ntị na nkọwa.
