Kukosha Kunoshamisa kweGreen Silicon Carbide Micropowder muIndasitiri yeSemiconductor
Indasitiri ye semiconductor yagara ichishandiswa tekinoroji yepamusoro, vanhu vachiwanzokurukura nyaya dzemhando yepamusoro dzakadai semichina ye photolithography uye dhizaini yema chip. Zvisinei, mukati meindasitiri iyi, zvimwe zvinhu zvinoita sezvisina basa zvine basa guru.Upfu hwegirini hwesilicon carbidendeimwe yezvinhu zvakadaro. Nhasi, ngatikurukurei nezvezvinhu izvi zvakakosha, tichishanda chinyararire mukugadzira zvinhu zve semiconductor.
Regai nditange nenyaya inonakidza. Gore rapera, ndakapinda mushoo yekutengeserana kweindasitiri ye semiconductor. Pabhokisi risingashamisi, mainjiniya akati wandei vaikurukura nemufaro nezvechishandiso chekukuya. Ndakanyatsoteerera, ndakavanzwa vachitaura kakawanda nezve "green silicon carbide micropowder." Ndakashamisika panguva iyoyo; zvainzwika sechinyakare cheindasitiri, saka chaigona sei kubatanidzwa nemidziyo ye semiconductor chaiyo? Gare gare, ndakaona kuti muindasitiri iyi, kana zvinhu zviri nyore, zvinonyanya kukosha.
Chii chinonzi green silicon carbide micropowder? Zvichitaurwa zviri nyore, chinhu chakagadzirwa nevanhu chakaoma, chinonyungudutswa muchoto chemagetsi chinopisa zvakanyanya kubva muzvinhu zvakaita sejecha re quartz ne petroleum coke. Chinowana zita racho nekuda kwekuchena kwaro kwakanyanya uye ruvara rwaro rwegirini rwakasiyana. Usarerutse zvidimbu zvidiki izvi; kuomarara kwazvo kunotevera dhaimani, asi zvine kugadzikana kwakanyanya kwekupisa uye kusagadzikana kwemakemikari.
Mukugadzira ma semiconductor, kutsetseka kwewafer kunosarudza zvakananga goho rema chips. Izvi zvinotisvitsa kuhunyanzvi hukuru hwekabhidhi yegirini yesiliconupfu hwe micropowder: chemical mechanical polishing (CMP). Lao Zhang, mainjiniya wekugadzira mawafer, anoshandisa fananidzo yakajeka: “Zvakafanana nekupa wafer 'kurapa kumeso'—kunobvisa mapundu nekusagadzikana pasina kusiya mavanga. Upfu hwe silicon carbide hwakaita se microcrystalline particles mukuchengetedza ganda kwepamusoro-soro—hunyoro asi hunoshanda.” Zvechokwadi, mukugadzira machipisi, kunyangwe chikamu chimwe mugumi che micron yekusagadzikana kunogona kukonzera kupfupika kana kuvhurika kwedunhu.
Kutarisira kupisa idambudziko rinoramba riripo muindasitiri ye semiconductor. Sezvo kubatanidzwa kwema chip kuchiwedzera, kupararira kwekupisa kunowedzera kuonekwa.Upfu hwegirini hwesilicon carbideine hunyanzvi hwakasiyana panyaya iyi: kuiisa muzvinhu zvinofambisa kupisa kunovandudza zvakanyanya kupararira kwekupisa. Mumwe mainjiniya wekupisa pakambani inozivikanwa ye chips akandiudza kuti, "Iye zvino tinoshandisa green silicon carbide micropowder yakakosha mu thermal paste yedu yepamusoro, iyo inovandudza kushanda kwekupisa nekupfuura 20%. Izvi zvinoponesa hupenyu mu 5nm ne 3nm process technologies."
Upfu hwegirini hwesilicon carbide hunonyanya kukosha mukugadzira michina ye semiconductor. Zvinhu zvakawanda zvakakosha mumichina ye lithography nemichina ye etching, iyo inogona kudhura makumi emamiriyoni e yuan, inoda kunyatsogadzirwa kwemashini zvakanyanya. Semuenzaniso, masisitimu e optical emichina ye lithography anoda kutaridzika kwakanyanya kwegirazi, zvichiita kuti zviomere kushandisa green silicon carbide micropowder.kukuya nemazvoMumwe murume ane ruzivo rwemakore makumi maviri akati, "Kushandisa chinhu ichi kunoda mari yakawanda. Saizi yezvikamu, huwandu hwezvinhu, uye pH zvinofanirwa kudzorwa nemazvo; kunyangwe kutsauka kudiki kunogona kukanganisa mhedzisiro yekupedzisira."
Zvakakosha kuziva kuti nekuwedzera kwezvinhu zve semiconductor zvechizvarwa chechitatu, green silicon carbide micropowder yawana chishandiso chitsva. Zvishandiso zve semiconductor zvakagadzirwa nesilicon carbide pachazvo zvinoda green silicon carbide micropowder yekukuya nekupukuta panguva yekugadzirisa. Inguva inonakidza - kushandisa silicon carbide kugadzirisa silicon carbide. Mutungamiriri wehunyanzvi wekambani yezvinhu zvitsva zve semiconductor akanyemwerera ndokuti, "Zvakafanana nekushandisa dhaimani kucheka dhaimani; chete sezvo zvinhu zvinogona kunzwisisana zvechokwadi."
Upfu hwegirini hwesilicon carbide hune basa rakasiyana mukutonga mhando. Mafekitori e semiconductor anoda kugadziriswa kwemidziyo nguva nenguva, kunyanya kucheneswa kwemitsetse yekufambisa uye makamuri ekuita. Nekuti upfu hwegirini hwesilicon carbide husina makemikari uye hahupi tsvina itsva, ndiyo inonyanya kufarirwa pakuchenesa. Mainjiniya wekugadzirisa akaburitsa pachena kuti, "Zvichienzaniswa nezvimwe zvinobvisa simba,upfu hwegirini hwesilicon carbidehaisiye maayoni esimbi pamadziro emukati memidziyo, izvo zvakakosha pakuchengetedza nzvimbo yakachena mukugadzirwa kwemachipisi.
Ehe, chinhu chimwe nechimwe chine mukana wekuvandudza. Matambudziko aripo iye zvino ari kutarisana ne green silicon carbide micropowder ari kunyanya mukudzora mitengo uye kugadzikana kwemhando. Maitiro akaoma ekugadzira uye kushandiswa kwesimba rakawanda zvinoita kuti mutengo wayo uve wakakwira. Uyezve, kugadzikana kwemhando dzakasiyana-siyana inyaya huru kune vashandisi. Zvisinei, makambani akati wandei anotungamira emuno ari kutogadzirisa nyaya idzi, zvishoma nezvishoma achiwedzera musiyano wezvigadzirwa zvinotengeswa kunze kwenyika nekuvandudza maitiro ekugadzira uye masisitimu ekutarisira mhando.
Tichitarisa mberi, sezvo tekinoroji ye semiconductor ichifambira mberi ichienda kuma process madiki uye mazinga epamusoro ekubatanidzwa, kudiwa kwe green silicon carbide micropowder kucharamba kuchikura. Izvi zvinonyanya kuitika muminda iri kubuda senge artificial intelligence chips, 5G communication chips, uye autonomous driving chips, izvo zvinowedzera kudiwa pakugadzirisa kwakaringana uye kupisa. Izvi zvinovhura mhando dzakasiyana dzemashandisirwo e green silicon carbide micropowder.
Ndinoyeuka mumwe murume agara nebasa muindasitiri achiti, “Indasitiri ye semiconductor yakaita sechando. Vanhu vanoona dhizaini yemachipisi chete uye kugadzirwa kukuru pamusoro penzvimbo, nepo zvinhu, maitiro, uye michina iri pasi penzvimbo zviri hwaro hunotsigira indasitiri yese.” Green silicon carbide micropowder chinhu chakakosha chezvinhu izvi zvekutanga. Zvingave zvisiri zvekukwezva maziso semuchina we lithography, asi zvinhu izvi "zvisingaonekwe" zvinotsigira kukura kweindasitiri yese ye semiconductor.
Nguva inotevera yaunoshandisa smartphone kana kutyaira mota yakangwara, zvichida funga kuti kuseri kwezvigadzirwa izvi zvetekinoroji yepamusoro ndiko kune mupiro wezvinhu "zvisingashamisi" zvakaita se green silicon carbide micropowder. Pamusoro pezvose, kufambira mberi kweindasitiri yega yega hakuparadzaniswi neaya magamba akanyarara, akazvipira ari kumashure.
