He aha ka Waʻa Wafer Quartz?

Waʻa wafer QuartzHe mea hana kūikawā ia i hoʻohana ʻia i ke kaʻina hana semiconductor, ʻo ia hoʻi no ka lawe ʻana a me ka lawe ʻana i nā wafers silicon i nā wahi wela kiʻekiʻe. Ma muli o kona kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika, hoʻohana nui ʻia nā waʻa wafer quartz i nā koi hana kiʻekiʻe a me nā ʻenehana kiʻekiʻe. Hana pinepine ʻia ia me ka mea quartz maʻemaʻe kiʻekiʻe (SiO2), ʻaʻole wale ka paʻa wela maikaʻi i nā mahana kiʻekiʻe akā mālama pū i ke kūpaʻa kemika, e pale ana i nā kinoea reactive a i ʻole nā ​​​​kemika mai ka haumia ʻana i ka wafer.
I ke kaʻina hana o ka hana semiconductor, ʻoi aku hoʻi i ka photolithography, ka waiho ʻana o ka ʻili lahilahi, ka etching a me nā kaʻina hana ʻē aʻe, pono e hana ʻia nā wafers i nā mahana kiʻekiʻe a koi pinepine i nā hopena i nā lewa kūikawā. I loko o kēia kaʻina hana, hiki i ka waʻa wafer, ma ke ʻano he mea lawe, ke kākoʻo paʻa a lawe i nā wafers, e hōʻoiaʻiʻo ana ʻaʻole i haumia ka ʻili wafer a hoʻemi i ka pōʻino i ka nui loa.

1. Hana ʻana i ka semiconductor
ʻO ka ʻoihana semiconductor ke kahua noi nui o nā waʻa wafer quartz. Hoʻohana pinepine ʻia nā waʻa wafer i ka hana ʻana o nā kaapuni hoʻohui ʻia (IC), me ka waiho ʻana o ka ʻili lahilahi (e like me ka waiho ʻana o ka mahu kemika a me ka waiho ʻana o ka mahu kino) a me nā kaʻina hana wela kiʻekiʻe e like me ka oxidation a me ka annealing. I loko o kēia mau kaʻina hana, kuleana ka waʻa wafer no ka lawe like ʻana i nā wafers i loko o ka reactor a me ka hōʻoia ʻana ua hoʻomehana like ʻia lākou ma ke kaʻina hana.
2. Ka waiho ʻana o ka mahu kemika (CVD)
I ke kaʻina hana CVD, hiki i nā waʻa wafer quartz ke lawe paʻa i nā wafers i nā mahana kiʻekiʻe e hōʻoia i ka like o nā waihona a hōʻemi i ka haumia kemika. Ma muli o nā waiwai o ka waʻa wafer, hiki iā ia ke pale aku i ka hoʻopilikia ʻana o nā hopena kemika i ka wā o ke kaʻina hana CVD, no laila e hōʻoiaʻiʻo ana i ka maikaʻi o nā wafers.
3. Kaʻina hana hoʻoheheʻe
He hana maʻamau ka hoʻoheheʻe ʻana i ke kaʻina hana semiconductor, e pili ana i ka hoʻomehana ʻana i ka wafer e hoʻokuʻu i ke kaumaha kūloko a hoʻoponopono paha i kekahi mau hemahema. Hoʻohana ʻia nā waʻa wafer Quartz i kēia kaʻina hana e lawe i nā wafer a hōʻoia i ka loaʻa ʻana o ka mālama wela like i loko o ka umu.
4. Ka ulu ʻana o ke aniani
I ka hana ʻana o kekahi mau mea holomua, hiki ke hoʻohana ʻia nā waʻa wafer quartz i nā kaʻina hana ulu kristal, ʻoi aku hoʻi i ka ulu ʻana o nā kristal silicon hoʻokahi a me nā mea semiconductor ʻē aʻe. I kēia mau noi, he mea nui loa ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika o nā waʻa quartz.

Pono ka hoʻolālā ʻana o nā waʻa wafer quartz e hoʻokō i nā koi he nui:

• Paʻa wela kiʻekiʻe:ʻOi aku ka nui o ka heheʻe o ka mea quartz ma mua o 1600°C, e hiki ai iā ia ke mālama i ke kūpaʻa kino a me ka kemika i nā wahi wela kiʻekiʻe.
• Ke kūpaʻa haʻalulu wela:He kūpaʻa maikaʻi loa ko Quartz i nā haʻalulu wela, hiki ke hoʻololi koke i nā loli o ka mahana, a ʻaʻole hiki ke nahā.
• ʻAʻohe haumia:He mea maʻemaʻe loa ka Quartz e hiki ke pale i ka haumia o ka ʻili wafer. I ke kaʻina hana semiconductor, hiki i kekahi haumia liʻiliʻi ke alakaʻi i nā hemahema huahana, no laila he mea nui loa ke koho ʻana i nā mea quartz.

Pehea e koho ai i ka waʻa wafer Quartz?

1. Helu a me ka nui o nā wafers
He ʻokoʻa nā koi o nā kaʻina hana like ʻole no nā waʻa wafer. Ma keʻano laulā, pono e hoʻoholo ʻia ka nui o ka waʻa wafer, ka helu o nā hakahaka, a me nā mea ʻē aʻe ma muli o ka nui a me ka nui o nā wafer e hana ʻia. ʻO ka nui o nā wafer e hoʻopilikia paha i ka hoʻolaha wela a me ke ʻano like, no laila pono ka noʻonoʻo pono ʻana i ka wā o ka hoʻolālā a me ke koho ʻana.
2. Mea quartz maʻemaʻe kiʻekiʻe
Ma muli o nā koi hoʻomaʻemaʻe kiʻekiʻe loa i ke kaʻina hana semiconductor, he mea nui loa ke koho ʻana i nā mea quartz maʻemaʻe kiʻekiʻe. Hiki i ka quartz o ka maʻemaʻe haʻahaʻa ke hoʻohaumia i nā wafers, e alakaʻi ana i ka emi ʻana o ka maikaʻi o ka huahana.
3. Ke kū'ē ʻana i ka haʻalulu wela
I kekahi mau kaʻina hana, pono nā waʻa wafer e hoʻololi pinepine ma waena o nā ʻano mahana like ʻole, no laila he mea nui loa ke kūpaʻa ʻana i ka haʻalulu wela. Loaʻa i ka mea Quartz ke kūpaʻa haʻalulu wela maikaʻi, akā ʻokoʻa paha ke kūpaʻa haʻalulu wela o nā waʻa wafer quartz i hana ʻia e nā mea hana like ʻole.
4. Ke kūpaʻa ʻana i ka palaho a me ke kūpaʻa kemika
ʻO nā mea hana kemika i hoʻohana ʻia i ka hana semiconductor he mea ʻino loa ia, no laila pono nā waʻa wafer quartz i ke kūpaʻa kemika kiʻekiʻe e pale aku ai i nā hopena me kēia mau mea kemika.
5. Kumukūʻai a me ke ola
I ka hana ʻana o nā mea lawe wafer quartz i nā wahi wela kiʻekiʻe, ʻike pinepine lākou i ka ʻaʻahu kino a me ka haehae. No laila, ʻo ko lākou ola lawelawe kekahi mea e pono e noʻonoʻo ʻia. ʻO ke koho ʻana i kahi waʻa wafer kūpono ke hiki ke hōʻemi pono i nā kumukūʻai hana lōʻihi.

 Pehea e mālama ai i ka waʻa Quartz Wafer?

1. Maʻemaʻe
I ka wā o ke kaʻina hana hoʻohana, hiki i nā waʻa wafer quartz ke hōʻiliʻili i kekahi mau mea kemika a i ʻole nā ​​​​​​ʻāpana liʻiliʻi, kahi e hoʻopilikia ai i ka maikaʻi o nā wafers. No laila, he mea nui loa ka hoʻomaʻemaʻe mau ʻana i ka waʻa wafer. ʻO nā ʻano hoʻomaʻemaʻe maʻamau e pili ana i ka hoʻohana ʻana i nā mea hoʻomaʻemaʻe ultrasonic, ka holoi ʻakika, a me nā hopena decontamination, a pēlā aku.
2. E nānā i nā māwae a me nā pohō
Ma muli o ke ʻano o ka pilikia o nā waʻa wafer quartz i nā mahana kiʻekiʻe loa a me nā kaomi mechanical, hiki ke loaʻa nā māwae a i ʻole ke komo ʻana ma hope o ka hoʻohana lōʻihi. E nānā mau i ka pono o ke ʻano o ka waʻa wafer a hoʻololi i nā ʻāpana i hōʻino ʻia i ka manawa kūpono e pale aku ai i nā pilikia i ka wā o ke kaʻina hana.
3. Kāohi i ka wela nui
ʻOiai he kūpaʻa maikaʻi ko ka quartz i ka haʻalulu wela, hiki nō ke hōʻino ʻia ma lalo o kekahi mau kūlana koʻikoʻi. No laila, i ka wā e hana ai, pono e makaʻala i ka pale ʻana i nā mahana kiʻekiʻe loa a me ka haʻalulu wela.
