Ma wafer a silicon, omwe ndi maziko a ma circuits ophatikizidwa ndi zida za semiconductor, amabwera ndi chinthu chosangalatsa - m'mphepete wosalala kapena kamphindi kakang'ono kodulidwa m'mbali. Kanthu kakang'ono aka kamagwira ntchito yofunika kwambiri pakugwira ma wafer ndi kupanga zipangizo. Monga opanga ma wafer otsogola, timafunsidwa kawirikawiri - chifukwa chiyani ma wafer a silicon ali ndi ma flat kapena ma notches? Munkhaniyi, tifotokoza ntchito ya ma flat ndi ma notches ndikukambirana kusiyana kwakukulu.
*Mukufuna ma wafer okhala ndi ma flat kapena notch? Tili ndi ma wafer ambiri a silicon omwe ndi okhazikika komanso opangidwa mwapadera omwe akupezeka kuti mugule pa intaneti kudzera pa WaferPro - okhala ndi ma flats, ma notch, ndi ma flats okonzedwa mwapadera omwe akugwirizana ndi zosowa zanu za silicon.
Udindo wa Ma Flats ndi Notches
Ma wafer a silicon ndi ofewa ndipo ayenera kusamalidwa bwino popanga zipangizo. Ma flat ndi ma notches amapereka malo oti makina agwire bwino wafer popanda kukhudza malo akuluakulu. Izi zimateteza pamwamba pa wafer wofunika ku kuwonongeka kulikonse kapena kuipitsidwa panthawi yokonza.
Pali mitundu iwiri ikuluikulu yomwe imagwiritsidwa ntchito mumakampani opanga ma semiconductor:
- Zosalala - izi ndi m'mbali zowongoka zodulidwa m'mbali mwa wafer yozungulira
- Manotchu - tinthu tating'onoting'ono tooneka ngati V m'mphepete mwa wafer
Makina omwe amagwira ma silicon wafers ali ndi ma end-effectors omwe amapangidwira kuti agwire bwino ma flats kapena notches kuti azinyamulidwa ndikuyikidwa bwino mu zida zopangira. Malo ogwirira amakhala ochepa kwambiri kuti alole malo okwanira omangira ma circuitry ophatikizika.
| Mtundu wa Wafer | Njira Yogwirira Yogwiritsidwa Ntchito |
|---|---|
| Wafer Wophwanyika | Chogwira ntchito kumapeto chokhala ndi m'mphepete mwathyathyathya |
| Wafer Wodulidwa | Chogwira ntchito kumapeto chokhala ndi chogwirira chooneka ngati V |
Izi zimathandiza kuti ma wafer aziyenda okha komanso mosamala pakati pa zida zopangira zinthu m'mizere yopangidwa ndi nsalu. Ogwiritsa ntchito amathanso kugwira ma wafer mosamala pamanja pogwiritsa ntchito malo otsetsereka/magawo otsetsereka akamakweza kapena kutsitsa kuchokera ku zotengera zamakaseti.
N’chifukwa Chiyani Muli ndi Ma Flats ndi Notches?
Kusagwirizana kwa malo osalala kapena otsetsereka kumathandiza kwambiri popanga ma wafer. Popanda izi, sipangakhale njira yolondola yowongolera ma wafer ndikujambula malo odulira.
Kulinganiza ndi Kujambula Mapu
Ma kristalo a silicon wafer ali ndi kapangidwe ka atomu kogwirizana ndi malo ndi njira zinazake - ndikofunikira kwambiri kuti wafer yatembenuzidwa bwanji!
Ma flat ndi notches amagwiritsidwa ntchito pokhazikitsa momwe ma crystal planes ndi ma axes awa amayendera. Ndi kusiyana kwa circumference, mainjiniya amatha kulumikizana molondola ndi crystal directions <110> kapena <100> zomwe zimafunika.
Kulinganiza kolunjika kumeneku kumatsimikizira mapu oyenera kuchokera ku zida za wafer kupita ku zida zomaliza za chip. Zophimba nkhope ndi zida zimalunjika malo enaake pamwamba pa wafer kuti apange nyumba ndi ma circuits ophatikizidwa. Kusalinganiza bwino kungapangitse zidazi kukhala zopanda ntchito!
Kusamalira ndi Chitetezo
Monga tanenera kale, mawonekedwe a zipilala/magawo amalola kuti zipangizo zopangira zigwiritsidwe ntchito bwino. Popanda malo ogwirira awa, chidachi chingapangitse mphamvu zosalamulirika komanso malo olumikizirana a wafer.
Kukhudzana kotereku kumabweretsa kuipitsidwa komwe kumawononga magwiridwe antchito. Malo ogwirira omwe ali pafupi ndi chitoliro amapewa kuipitsidwa kumeneku pomwe amateteza bwino chitolirocho.
Kuphatikiza apo, mainjiniya nthawi zambiri amapewa ngodya zakuthwa ndi m'mbali akamagwira zinthu zosalimba monga ma wafer a silicon. Zosalala ndi zozungulira zimachepetsa ming'alu kapena kusweka poyerekeza ndi momwe zimagwirira ndi m'mbali zakuthwa.
Ma flat kapena ma notches amawonjezera kukhazikika kwa magwiridwe antchito poyeretsa malo opangira chipangizocho.
Ma Wafer Flats vs. Wafer Notch
Ma flat ndi ma notches onse amagwira ntchito yofanana, ndiye chifukwa chiyani ali ndi mitundu iwiri? Pali kusiyana pang'ono ...
Ma flats amatenga malo ambiri pamphepete koma amapereka malo ogwirira aakulu komanso owongoka. Ma notches ndi ochepa koma amapereka malo ogwirira otetezeka a vertex.
Palinso zifukwa zakale zomwe zimadalira kusintha kwa mafakitale. Poyamba, ma flats anali osavuta kuwona ndi kugwiritsa ntchito kwa akatswiri a ma wafer. Pamene makina odzipangira okha ankawonjezeka, ma notches ankatha kubisika mkati mwa nsagwada zogwira ntchito.
Makamaka mtundu wake umadalira kapangidwe ka zida ndi zofunikira kuchokera kwa ogulitsa. Zipangizo zambiri zopangira zinthu tsopano zimagwira ntchito mosavuta ndi zopyapyala kapena zopindika.
Choncho opanga zinthu za semiconductor amagwiritsa ntchito muyezo woyenera bwino m'malo mosakaniza ndi kusakaniza. Mafakitale ena amagwiritsa ntchito zinthu zonse zosalala, ena amagwiritsa ntchito zinthu zonse kuti zinthu zikhale zosavuta.
Monga opanga ma wafer otsogola, tili ndi kuthekera kopereka ma wafers okhala ndi ma flat kapena notches monga momwe makasitomala amafunira pa nsalu zawo.
Kutenga
Ngakhale kuti ndi chinthu chosavuta kuchigwiritsa ntchito, ma flat ndi notches zimathandiza kuti zinthu zigwire bwino ntchito, zikhale bwino, komanso kuti zikhale zotetezeka pokonza ma silicon wafer. Kusasinthasintha kumeneku kumalola kuti zinthu ziyende bwino komanso kupatsa zida mwayi wopeza ma grip wafer popanda kuwonongeka pamwamba.
Nthawi ina mukayang'ana dera lolumikizidwa, ganizirani za gawo lofunika kwambiri lomwe kachipangizo kakang'ono kapena kosalala kanali nalo popanga!
Popanda ma flats kapena notches, ma transistors a trillion-plus pa silicon sakanatha kukhala zida zamagetsi zamakono zomwe zikugwira ntchito. Chifukwa china chomwe zinthu zosaoneka ngati zazing'ono ndizofunikira kwambiri popanga ma semiconductor!
