I loko o ka ʻoihana semiconductor, kahi e hiki ai i kahi micron hoʻokahi ke lilo i ʻokoʻa ma waena o kahi pūʻulu hua kiʻekiʻe a me kahi hāʻule pipiʻi, he mea koʻikoʻi ke koho ʻana i ka mea metrology. I ka wā e hoʻokuke ai ka lithography a me ka nānā ʻana o ka wafer i nā palena o ka physics, ke hōʻea nei ka metala kuʻuna a me ka granite kiʻekiʻe i ko lākou mau palena.
Ua kū mai ka Alumina Ceramic (Al2O3) ma ke ʻano he hopena paʻa no nā mea hana lako semiconductor. Me kahi manawa paʻa pololei e hiki ke ʻoi aku ma mua o nā mea kuʻuna ma mua o 10 mau makahiki, ʻaʻole ia he mea hoʻohiwahiwa nā keramika—he mea pono ia no ke kūkulu ʻana.
No ke aha he alumina ceramic no nā semiconductors?
Ma mua o ka luʻu ʻana i loko o nā noi, he mea nui e hoʻomaopopo i ka ʻaoʻao "triple-threat" kūikawā o ka mea:
-
Ke kūpaʻa wela: ʻO kahi coefficient haʻahaʻa o ka hoʻonui wela (≈7 × 10^{-6}/K) e hōʻoiaʻiʻo ana e mau ana nā ana me ka nānā ʻole i ka wela i hana ʻia e nā lako wikiwiki.
-
ʻAʻole Magnetic & ʻAʻole Alakaʻi: He mea nui no nā wahi hakahaka a me ka lithography kukuna electron koʻikoʻi kahi e hiki ai i ka hoʻopilikia magnetic ke hoʻohuli i nā kukuna.
-
ʻAʻohe ʻino: ʻAʻole e like me ke kila, he inert kemika nā keramika, e kūpono ai me nā kaʻina hana hoʻomaʻemaʻe lumi maʻemaʻe a me nā wahi kinoea ʻino.
5 mau noi koʻikoʻi i nā lako Semiconductor
1. Nā Pae Mīkini Lithography
Pono ka photolithography hou i ke kau ʻana ma ka pae nanometer. ʻO nā huinahā seramika a me nā ʻāpana kūkulu e lawelawe ma ke ʻano he "kuhikuhi kumu" no ke kahua wafer. ʻO kā lākou lakio paʻakikī-i-kaumaha kiʻekiʻe e ʻae i ka wikiwiki wikiwiki me ka ʻole o ka haʻalulu a i ʻole ke "kani" e pili ana me nā mea kaumaha.
2. Nānā Wafer & Metrology
I loko o nā ʻōnaehana geometry wafer, hoʻohana ʻia nā Ceramic Master Squares e hoʻoponopono i ka perpendicularity a me ka pololei o nā axes scanning. Ma muli o ka mālama ʻana o ka ceramic i kona ʻano ma mua o hoʻokahi ʻumi makahiki, pono kēia mau mīkini i nā pōʻaiapuni recalibration liʻiliʻi loa, e hoʻonui ana i ka manawa hana no ka fab.
3. ʻAha Kūkākūkā Pololei o nā Keʻena Vacuum
Hoʻomaʻamaʻa pinepine ʻia ka ʻākoakoa ʻana o ka semiconductor i nā wahi vacuum kahi i kaupalena ʻia ai ka lubrication. Hāʻawi nā ana keramika i kahi kuhikuhi pololei "maloʻo" ʻaʻole e hoʻonui i ke kinoea a i ʻole e hoʻohaumia i ka vacuum, e hōʻoiaʻiʻo ana ua hoʻohālikelike ʻia nā ʻāpana o loko i nā ʻae ʻana o sub-micron.
4. Hoʻāʻo Uila Pinepine Kiʻekiʻe
No ka hoʻāʻo ʻana i nā ʻāpana wikiwiki kiʻekiʻe, hiki i kekahi mea hoʻopilikia magnetic a conductive paha mai ka mea ana ke hoʻopilikia i nā hopena. ʻO ke ʻano non-magnetic o ka alumina ceramic e lilo ia i mea kūpono no nā mea hoʻopaʻa kāleka probe a me nā ana hoʻonohonoho.
5. Nā Luna Hoʻoponopono Lumi Maʻemaʻe
Ma nā lumi maʻemaʻe ISO Class 1, he mea haumia kapu ka ʻōpala. Pono nā ana kila i nā ʻili ʻaila e pale aku i ka oxidation, he pilikia haumia nui ia. ʻAʻole pono nā ana seramika i ka ʻaila a hiki ke hoʻomaʻemaʻe ʻia me ka waiʻona isopropyl, e mālama ana i kahi ʻano "zero-particle" no 10+ mau makahiki.
ʻO ka "Pōmaikaʻi 10-Makahiki"
ʻOiai paha e ʻūlū a ʻaʻahu paha nā ana hao ma hope o kekahi mau makahiki o ka hoʻohana nui ʻana, he paʻa loa ke ʻano molekala o ka Alumina maʻemaʻe kiʻekiʻe. Ke hoʻohana ʻia ma ke ʻano he Ceramic Square a i ʻole Straight Edge, ʻo ka paʻakikī o ka mea (e hoʻokokoke ana i ka sapphire) e pale ai i ka hōʻino ʻana o ka ʻili microscopic e hoʻoulu pinepine ai i ka pololei e "lele" i ka hala ʻana o ka manawa.
No kahi semiconductor OEM, ʻo ia hoʻi ka hōʻemi ʻana he 10-fold i nā kumukūʻai mālama lōʻihi a me kahi pae kiʻekiʻe o ka hilinaʻi i ka pololei o ke ola o ka mīkini.
