Kodi mwala wawung'ono umathandiza bwanji kuti miyala ya granite isawonongeke?

Mu "fakitale yapamwamba" yopanga ma chip, wafer iliyonse yofanana ndi msomali imakhala ndi ma circuits enieni, ndipo chinsinsi chodziwira ngati ma circuits awa angapangidwe bwino ndi chobisika mu mwala wosayerekezeka - uwu ndi granite. Lero, tiyeni tikambirane za "chida chachinsinsi" cha granite - mphamvu yake yochepetsera chinyezi - ndi momwe imakhalira "mngelo woteteza" wa zida zowunikira ma wafer.
Kodi kunyowetsa madzi ndi chiyani? Kodi miyala imathanso "kuyamwa kugwedezeka"?
Kuchepetsa mphamvu ya madzi kumamveka ngati kwaukadaulo, koma kwenikweni, mfundo yake ndi yosavuta. Tangoganizani kuti mwangoyima mwadzidzidzi mukuthamanga. Ngati palibe kutsekereza, thupi lanu lidzathamanga patsogolo chifukwa cha kulephera. Ndipo kuchepetsa mphamvu ya madzi kumakhala ngati dzanja losaoneka, zomwe zimakuthandizani "kuswa" mwachangu. Kapangidwe ka mkati mwa granite kamapangidwa ndi makristalo amchere olumikizidwa monga quartz ndi feldspar, ndipo pali ming'alu yambiri ndi malo okangana pakati pa makristalo awa. Pamene kugwedezeka kwakunja kumatumizidwa ku granite, ming'alu iyi ndi malo okangana amayamba "kugwira ntchito", kusintha mphamvu ya kugwedezeka kukhala mphamvu yotentha ndikuyichotsa pang'onopang'ono, zomwe zimapangitsa kuti kugwedezeka kuime mwachangu. Izi zili ngati kukhazikitsa "super shock absorber" pa chipangizocho, zomwe zimapangitsa kuti chisakhalenso "kugwirana chanza".
Kusanthula kwa Wafer: Cholakwika chaching'ono chingayambitse cholakwika chachikulu
Zipangizo zojambulira ma wafer zili ngati makamera olondola omwe "amajambula" ma wafer, kuzindikira ndi kujambula mawonekedwe a circuit pa nanoscale. Komabe, panthawi yogwira ntchito ya zidazi, kuzungulira kwa mota ndi kayendedwe ka zida zamagetsi zonse zimapanga kugwedezeka kwamphamvu kwambiri. Ngati kugwedezeka kumeneku sikulamulidwa, lenzi yojambulira "idzasanduka" ngati kamera yosakhazikika, zomwe zimapangitsa kuti deta yozindikira isadziwike bwino komanso ngakhale kutaya wafer yonse mwachindunji.

Pamene maziko achitsulo wamba akumana ndi kugwedezeka, nthawi zambiri "amagunda mwamphamvu motsutsana ndi mwamphamvu", ndipo kugwedezeka kumaonekera mmbuyo ndi mtsogolo mkati mwa chitsulocho, zomwe zimapangitsa kuti kugwedezekako kukhale koopsa kwambiri. Granite, yokhala ndi mphamvu yabwino kwambiri yochepetsera chinyezi, imatha kuyamwa mphamvu yopitilira 80% ya kugwedezeka. Chitsanzo chenicheni cha fakitale ina ya semiconductor chikuwonetsa kuti maziko a granite asanasinthidwe, m'mphepete mwa zithunzi za wafer zomwe zidatengedwa ndi zida zowunikira zinali zosawoneka bwino, ndi kupotoka kwakukulu mpaka ±3μm. Pambuyo posinthira ku maziko a granite, kumveka bwino kwa chithunzicho kunasintha kwambiri, kupotoka kunachepetsedwa kufika ±0.5μm, ndipo kuchuluka kwa zokolola kunakwera kuchoka pa 82% kufika 96%!
Vuto la Resonance: Kodi Granite "Imathetsa Bwanji Ngozi"?
Kupatula kugwedezeka kwa chipangizocho, kugwedezeka pang'ono kuchokera kumalo akunja (monga momwe makina oyandikana nawo amagwirira ntchito kapena mapazi a ogwira ntchito akuyenda) kungayambitsenso mavuto akulu. Ngati kugwedezeka kwakunja kukugwirizana ndi kuchuluka kwa chipangizocho, kugwedezeka kumachitika, monga momwe jelly imagwedezekera, kuchuluka kwa mphamvu kumakulirakulira, momwe mumagwedezera kwambiri. Makhalidwe a granite onyowa ali ngati kuyika "maearplugs osamveka" pa chipangizocho, kukulitsa kuchuluka kwa ma resonant frequency a chipangizocho ndikupangitsa kuti chisagwirizane ndi dziko lakunja. Deta ikuwonetsa kuti mutagwiritsa ntchito maziko a granite, chiopsezo cha kugwedezeka kwa chipangizocho chachepetsedwa ndi 95%, ndipo kukhazikika kwawonjezeka katatu!
Kuzindikira "kuchepa" m'moyo
Ndipotu, mfundo ya damping ndi yofala kwambiri m'moyo watsiku ndi tsiku. Zoyamwa motoka zimatithandiza kuyendetsa bwino m'misewu yodzaza ndi mikwingwirima, ndipo ntchito yoletsa phokoso ya mahedifoni imatha kuletsa phokoso lakunja. Zonsezi zimapangitsa kuti zikhale zokhazikika mwa "kunyamula mphamvu". Granite yabweretsa luso limeneli kwambiri ndipo yakhala chinthu chofunikira kwambiri pakupanga ma chip.

Nthawi ina mukadzaona granite, musangoitenga ngati mwala wamba! Mu dziko lamakono la kupanga zinthu zopangidwa ndi ma semiconductor, ndi zinthu zomwe zimaoneka ngati zachilendo zomwe, ndi "mphamvu zawo zazikulu" zapadera, zimayendetsa ukadaulo patsogolo mosalekeza.
