He aha ka Granite i hoʻohana ʻia i nā mea hana wafer?

He mea kaulana ʻo Granite i ka ʻoihana hana wafer ma muli o kona mau ʻano mechanical a me ka lōʻihi.He pōhaku maoli ia i ʻeli ʻia mai nā quarries a puni ka honua a ua hoʻohana ʻia no nā kenekulia no nā kumu hana like ʻole, me ka hana ʻana i nā lako semiconductor.Ma kēia ʻatikala, e kūkākūkā mākou i nā waiwai o ka granite a me kāna mau noi like ʻole i nā lako hana wafer.

Na waiwai o Granite

ʻO ka Granite he pōhaku igneous i haku ʻia me ka mica, feldspar, a me ka quartz.ʻIke ʻia ʻo ia no kona ikaika ʻokoʻa, paʻakikī, a me ka lōʻihi, e lilo ia i mea kūpono no nā noi e koi ana i ka pololei kiʻekiʻe a me ka pololei.He haʻahaʻa haʻahaʻa ko Granite o ka hoʻonui wela, ʻo ia hoʻi, ʻaʻole ia e hoʻonui a ʻaelike paha ma muli o ka hoʻololi ʻana o ka mahana, e paʻa loa ia.Hoʻohui ʻia, kūpaʻa ka granite i ka corrosion a me nā kemika, e lilo ia i mea kūpono no ka hoʻohana ʻana i nā wahi paʻakikī.

Noi o Granite i ka Wafer Processing Lako

ʻO Granite kahi mea i hoʻohana nui ʻia i ka ʻoihana hana wafer ma muli o kāna hui kūʻokoʻa o nā waiwai.Eia kekahi o nā noi o ka granite i nā mea hana wafer.

1. Mea Hana Metrology

Hoʻohana pinepine ʻia ka Granite i ka hana ʻana i nā mea hana metrology, e like me nā mīkini ana hoʻonohonoho (CMMs) a me nā ʻōnaehana ana ʻana.Pono kēia mau mea hana i nā ʻili paʻa e hiki ke pale i nā haʻalulu a me ka wela.ʻO ka ʻoʻoleʻa kiʻekiʻe a me ka hoʻonui haʻahaʻa wela o ka granite e lilo ia i mea kūpono no ia mau noi.

2. Wafer Chucks

Hoʻohana ʻia nā pahu wafer e paʻa i nā wafers i ka wā o ka hana ʻana.Pono kēia mau puʻupuʻu i kahi ʻili palahalaha a paʻa i mea e pale ai i ka wafer mai ke kaua a i ʻole ka piko.Hāʻawi ka Granite i kahi papa pālahalaha i kūpaʻa loa a kūpaʻa i ka warping, e lilo ia i mea maikaʻi loa no nā chucks wafer.

3. Mea Hana Mechanical Polishing (CMP).

Hoʻohana ʻia nā mea hana CMP e poli i nā wafers i ka wā hana.Pono kēia mau mea hana i kahi paepae paʻa e hiki ke pale i nā haʻalulu a me ka wela.ʻO ka ʻoʻoleʻa maikaʻi a me ka hoʻonui haʻahaʻa wela o ka granite e lilo ia i mea kūpono no nā mea hana CMP.

4. Na Lako Nana Wafer

Hoʻohana ʻia nā mea nānā wafer e nānā i nā wafers no nā hemahema a me nā hemahema.Pono kēia mau mea hana i kahi ʻili paʻa a palahalaha e hōʻoia i nā ana pololei.Hāʻawi ʻo Granite i kahi ʻili paʻa a paʻa i ka pale ʻana i ka warping, e lilo ia i mea kūpono no nā lako nānā wafer.

Ka hopena

I ka hopena, ʻo ka granite kahi mea i hoʻohana nui ʻia i ka ʻoihana hana wafer ma muli o kona ʻano mechanical a me ka lōʻihi.Hoʻohana maʻamau ia i ka hana ʻana i nā mea hana metrology, wafer chucks, CMP mea hana, a me nā mea nānā wafer.ʻO ka hui like ʻole o nā waiwai e lilo ia i mea kūpono no nā noi e koi ana i ka pololei kiʻekiʻe a me ka pololei.Me kona mau pono he nui, ua lilo ka granite i mea koho kaulana no na lako hana wafer, a e ulu mau ana ka hoohana ana i keia mua aku.
