ʻO ka waiwai kū hoʻokahi o ka Green Silicon Carbide Micropowder ma ka ʻoihana Semiconductor
Ua like mau ka ʻoihana semiconductor me ka ʻenehana kiʻekiʻe, me ka poʻe e kūkākūkā pinepine ana i nā kumuhana kiʻekiʻe e like me nā mīkini photolithography a me ka hoʻolālā chip. Eia nō naʻe, i loko o kēia ʻoihana, he kuleana koʻikoʻi kekahi mau mea liʻiliʻi ʻole.ʻO ka pauka microcarbide silicon ʻōmaʻomaʻoʻo ia kekahi o ia mau mea. I kēia lā, e kūkākūkā kākou i kēia mea kūikawā, e hana mālie ana i kona ala ma o ka hana semiconductor.
E hoʻomaka wau me kahi moʻolelo hoihoi. I ka makahiki i hala, ua hele au i kahi hōʻikeʻike kālepa ʻoihana semiconductor. Ma kahi hale kūʻai haʻahaʻa, ua kūkākūkā nui kekahi mau ʻenekinia i kahi ʻāpana o nā lako wili. I ka hoʻolohe pono ʻana, ua lohe pinepine au iā lākou e ʻōlelo ana i ka "green silicon carbide micropowder." Ua kānalua wau i kēlā manawa; ua like ia me kahi abrasive ʻoihana kuʻuna, no laila pehea e hiki ai ke hoʻopili ʻia me nā semiconductors precision? Ma hope mai, ua ʻike au ma kēia ʻoihana, ʻo ka mea maʻalahi loa, ʻoi aku ka koʻikoʻi.
He aha maoli ka pauka silicon carbide ʻōmaʻomaʻo? I ka ʻōlelo maʻalahi, he mea paʻakikī loa ia i hana ʻia e ke kanaka, i hoʻoheheʻe ʻia i loko o kahi umu uila wela kiʻekiʻe mai nā mea maka e like me ke one quartz a me ka petroleum coke. Loaʻa kona inoa mai kona maʻemaʻe kiʻekiʻe a me ke kala ʻōmaʻomaʻo ʻokoʻa. Mai hoʻohaʻahaʻa i kēia mau ʻāpana liʻiliʻi; ʻo ko lākou paʻakikī ka lua ma mua o ke daimana, akā loaʻa iā lākou ke kūpaʻa wela kiʻekiʻe a me ka inertness kemika.
I ka hana ʻana o ka semiconductor, hoʻoholo pololei ka palahalaha o ka wafer i ka hua o ka chip. Lawe mai kēia iā mākou i ke akamai koʻikoʻi ocarbide silicon ʻōmaʻomaʻomicropowder: ka hoʻopili ʻana i nā mea hana kemika (CMP). Hoʻohana ʻo Lao Zhang, he ʻenekinia hana ma kahi hale hana wafer, i kahi hoʻohālikelike maopopo: "Ua like ia me ka hāʻawi ʻana i kahi wafer i kahi 'lāʻau maka' - e hoʻomaʻemaʻe ana i nā puʻupuʻu a me nā ʻano like ʻole me ka waiho ʻole ʻana i nā ʻōpala. ʻO ka micropowder silicon carbide ʻōmaʻomaʻo e like me nā ʻāpana microcrystalline i loko o ka mālama ʻili kiʻekiʻe - akahai akā maikaʻi." ʻOiaʻiʻo, i ka hana ʻana i nā chip, ʻoiai he mau hapaʻumi o ka micron o ka ʻano like ʻole hiki ke hana i kahi kaapuni pōkole a wehe paha.
He pilikia mau ka hoʻokele wela i ka ʻoihana semiconductor. I ka piʻi ʻana o ka hoʻohui ʻana o nā chip, lilo ka hoʻolaha wela i mea koʻikoʻi.ʻO ka pauka microcarbide silicon ʻōmaʻomaʻohe mākaukau kūikawā kona ma kēia ʻano: ʻo ka hoʻohui ʻana i nā mea hoʻoili wela e hoʻomaikaʻi nui i ka hoʻoheheʻe ʻana o ka wela. Ua haʻi mai kekahi ʻenekinia wela ma kahi ʻoihana chip kaulana iaʻu, "Ke hoʻohana nei mākou i kahi micropowder silicon carbide ʻōmaʻomaʻo kūikawā i kā mākou hoʻopili wela kiʻekiʻe, kahi e hoʻomaikaʻi ai i ka pono o ka hoʻoheheʻe ʻana o ka wela ma mua o 20%. He mea hoʻopakele ola kēia i nā ʻenehana hana 5nm a me 3nm."
ʻOi aku ka pono o ka micropowder silicon carbide ʻōmaʻomaʻo i ka hana ʻana i nā lako semiconductor. Nui nā ʻāpana koʻikoʻi i nā mīkini lithography a me nā mīkini etching, hiki ke uku ʻia he ʻumi miliona yuan, pono ka pololei o ka mīkini. No ka laʻana, koi nā ʻōnaehana optical o nā mīkini lithography i ka flatness aniani kiʻekiʻe loa, e pono ai ka hoʻohana ʻana i ka micropowder silicon carbide ʻōmaʻomaʻo nowili pololeiUa ʻōlelo kekahi koa kahiko me 20 mau makahiki o ka ʻike, "He mea paʻakikī loa ka hoʻohana ʻana i kēia mea. Pono e hoʻomalu pono ʻia ka nui o nā ʻāpana, ka nui o ka ʻāpana, a me ka waiwai pH; ʻoiai ka ʻokoʻa iki loa e hiki ke hoʻopilikia i ka hopena hope loa."
He mea kūpono ke hoʻomaopopo ʻana me ka piʻi ʻana o nā mea semiconductor hanauna ʻekolu, ua loaʻa i ka micropowder silicon carbide ʻōmaʻomaʻo kahi noi hou. Pono nā mea semiconductor i hoʻokumu ʻia i ka silicone carbide i ka micropowder silicon carbide ʻōmaʻomaʻo no ka wili ʻana a me ka hoʻopili ʻana i ka wā e hana ai. He pōʻaiapuni hoihoi ia—e hoʻohana ana i ka silicon carbide e hana i ka silicon carbide. Ua minoʻaka ka luna loea o kahi hui mea hou semiconductor a ʻōlelo akula, "Ua like ia me ka hoʻohana ʻana i kahi daimana e ʻoki i kahi daimana; ʻo nā mea like wale nō e hiki ke hoʻomaopopo maoli kekahi i kekahi."
He kuleana kūikawā ko ka silicon carbide micropowder ʻōmaʻomaʻo i ka kaohi ʻana i ka maikaʻi. Pono nā hale hana semiconductor i ka mālama pono ʻana i nā lako hana maʻamau, ʻoiai ka hoʻomaʻemaʻe ʻana i nā laina conveyor a me nā keʻena hana. No ka mea, he inert kemika ka silicon carbide micropowder ʻōmaʻomaʻo a ʻaʻole hoʻokomo i nā mea haumia hou, ʻo ia ka mea makemake ʻia no nā kaʻina hana hoʻomaʻemaʻe. Ua hōʻike kekahi ʻenekinia mālama, "Ke hoʻohālikelike ʻia me nā mea abrasive ʻē aʻe,pauka micropoda silicon carbide ʻōmaʻomaʻoʻaʻole e waiho i nā iona metala ma nā paia o loko o nā lako, he mea nui ia no ka mālama ʻana i kahi ʻano maʻemaʻe i ka hana ʻana i nā ʻāpana.
ʻOiaʻiʻo, aia kahi e pono ai ka hoʻomaikaʻi ʻana i kēlā me kēia mea. ʻO nā pilikia o kēia manawa e kū nei i ka silicon carbide micropowder ʻōmaʻomaʻo, aia ma ke kaohi ʻana i ke kumukūʻai a me ke kūlike o ka maikaʻi. ʻO ke kaʻina hana paʻakikī a me ka hoʻohana ʻana i ka ikehu kiʻekiʻe e kōkua i kona kumukūʻai kiʻekiʻe. Eia kekahi, ʻo ke kūlike ma waena o nā ʻāpana he mea nui ia no nā mea hoʻohana. Eia nō naʻe, ke hoʻoponopono nei kekahi mau ʻoihana kūloko alakaʻi i kēia mau pilikia, e hoʻemi mālie ana i ka hakahaka me nā huahana i lawe ʻia mai ma o ka hoʻomaikaʻi ʻana i nā kaʻina hana a me nā ʻōnaehana hoʻokele maikaʻi.
I ka nānā ʻana i mua, i ka ulu ʻana o ka ʻenehana semiconductor i nā kaʻina hana liʻiliʻi a me nā pae kiʻekiʻe o ka hoʻohui ʻana, e hoʻomau ka ulu ʻana o ke koi no ka micropowder silicon carbide ʻōmaʻomaʻo. He ʻoiaʻiʻo loa kēia ma nā kahua e kū mai ana e like me nā chips naʻauao artificial, nā chips kamaʻilio 5G, a me nā chips hoʻokele autonomous, kahi e kau ai i nā koi kiʻekiʻe aʻe ma ka pololei o ka hana a me ka hana hoʻoheheʻe wela. Wehe kēia i kahi ākea ākea o nā noi no ka micropowder silicon carbide ʻōmaʻomaʻo.
Ke hoʻomanaʻo nei au i kahi loea ʻoihana i ʻōlelo ai, "Ua like ka ʻoihana semiconductor me kahi hau hau. ʻO ka mea a ka poʻe e ʻike ai, ʻo ia wale nō ka hoʻolālā chip a me ka hana nui ma luna o ka ʻili, ʻoiai ʻo nā mea hana, nā kaʻina hana, a me nā lako ma lalo o ka ʻili ke kumu e kākoʻo ana i ka ʻoihana holoʻokoʻa." ʻO ka silicon carbide micropowder ʻōmaʻomaʻo kahi ʻāpana koʻikoʻi o kēia mau mea kumu. ʻAʻole paha ia e like me ka mīkini lithography, akā ʻo kēia mau mea "ʻike ʻole ʻia" e kākoʻo ana i ka hoʻomohala ʻana o ka ʻoihana semiconductor holoʻokoʻa.
I ka manawa aʻe e hoʻohana ai ʻoe i kahi kelepona akamai a hoʻokele paha i kahi kaʻa akamai, e noʻonoʻo paha ma hope o kēia mau huahana ʻenehana kiʻekiʻe e waiho ana ka hāʻawi ʻana o nā mea "hoʻohaʻahaʻa" e like me ka micropowder silicon carbide ʻōmaʻomaʻo. Ma hope o nā mea a pau, ʻaʻole hiki ke hoʻokaʻawale ʻia ka holomua o kēlā me kēia ʻoihana mai kēia mau "hero" hāmau a hoʻolaʻa ʻia ma hope o nā hiʻohiʻona.
