Ii-silicon wafers, isiseko seesekethe ezidityanisiweyo kunye nezixhobo ze-semiconductor, ziza nesici esinomdla - umphetho othe tyaba okanye i-notch encinci esikwe ecaleni. Le nkcukacha incinci inenjongo ebalulekileyo yokuphatha ii-wafer kunye nokwenziwa kwezixhobo. Njengomvelisi ophambili wee-wafers, sibuzwa rhoqo - kutheni ii-silicon wafers zine-flats okanye ii-notches? Kweli nqaku, siza kuchaza umsebenzi wee-flats kunye nee-notches kwaye sixoxe ngomahluko obalulekileyo.
*Ufuna ii-wafers ezinee-flats okanye i-notch? Sineentlobo ngeentlobo zee-wafers ze-silicon ezisemgangathweni nezenziwe ngokwezifiso ezifumanekayo ukuze uzi-odole kwi-intanethi nge-WaferPro - ezinee-flats ezisemgangathweni ze-SEMI, ii-notches, kunye nee-flats ezenziwe ngokwezifiso ngokweemfuno zakho ze-silicon.
Indima yeeFlethi kunye neeNotshi
Ii-wafer ze-silicon zibuthathaka kwaye kufuneka ziphathwe ngokuchanekileyo ngexesha lokwenziwa kwezixhobo. Iiflethi kunye nee-notches zibonelela ngendawo yokuba oomatshini babambe i-wafer ngokukhuselekileyo ngaphandle kokuthinta iindawo eziphambili. Oku kukhusela umphezulu we-wafer oxabisekileyo kuyo nayiphi na ingozi okanye ungcoliseko ngexesha lokucubungula.
Kukho iintlobo ezimbini eziphambili ezisetyenziswa kwishishini le-semiconductor:
- Iiflethi – ezi ziincam ezithe tye ezisikwe ecaleni kwe-wafer engqukuva
- Iinotshi – ii-indents ezincinci ezimile okwe-V kumjikelezo we-wafer
Oomatshini abaphatha ii-silicon wafers banezixhobo zokugqibela ezenzelwe ngokukodwa ukubamba iiflethi okanye ii-notches ngokuqinileyo ukuze zithuthwe kwaye zilungelelaniswe kwizixhobo zokwenza. Indawo yokubamba igcinwa incinci kakhulu ukuvumela indawo ephezulu yokwakha iisekethe ezidibeneyo.
| Uhlobo lweWafer | Indlela Yokubamba Esetyenzisiweyo |
|---|---|
| I-wafer ethe tyaba | Isiphumo sokugqibela esine-flat edge grip |
| I-Wafer eNotched | Isipheli-siphumo esinomgca omile njengo-V |
Oku kuvumela ukuhamba ngokuzenzekelayo nangokukhuselekileyo kwee-wafers phakathi kwezixhobo zokusebenza kwimigca yefab. Abaqhubi banokuphatha ngononophelo ii-wafers ngesandla ngama-flats/notches xa belayisha okanye bekhupha kwiikhonteyina zekhasethi.
Kutheni Uneziflethi kunye neeNotshi?
Ukungalingani kwe-flat okanye i-notch kusebenza njengomsebenzi obalulekileyo wokulungelelanisa ukwenza i-wafer. Ngaphandle kwezi, bekungayi kubakho ndlela yokujonga ngokuthembekileyo i-wafer kunye nokumakisha iindawo ze-die.
Ulungelelwaniso kunye neMephu
Iikristale ze-silicon wafer zinezakhiwo zeathomu ezihambelana nemigangatho ethile kunye nezikhokelo - kubaluleke kakhulu ukuba i-wafer ijikeleziswa njani!
Iiflethi kunye neenotshi zisetyenziselwa ukuseka indlela ezi planes zekristale kunye nee-axes ezijongwa ngayo. Ngenxa yokungalingani kwi-perimeter, iinjineli zinokuhambelana ngokuchanekileyo nezikhokelo zekristale ezingaphantsi kwe-110> okanye ezingaphantsi kwe-100> ezifunekayo.
Olu lungelelwaniso lokuqondisa luqinisekisa ukubala kakuhle ukusuka kwi-wafer ukuya kwizixhobo zokugqibela ze-chip. Iimaski nezixhobo zijolise kwiindawo ezithile kumphezulu we-wafer ukuze kwakhiwe izakhiwo kunye neesekethe ezidibeneyo. Ukulungelelaniswa okungalunganga kungenza ezi zixhobo zingasebenzi!
Ukuphatha kunye noKhuseleko
Njengoko sele kukhankanyiwe, imilo yeeflethi/iinotshi ivumela ukuphathwa ngokukhuselekileyo kwezixhobo zokwenza. Ngaphandle kwezi ndawo zokubamba, isixhobo singabeka amandla angalawulekiyo kunye nemiphezulu ye-wafer yoqhagamshelwano.
Ukudibana okunjalo kubeka emngciphekweni ungcoliseko oluya konakalisa ukusebenza. Iindawo zokubamba ezijikeleze umngcelele ziyayiphepha le ngcoliseko ngelixa zikhusela i-wafer ngcono.
Ngaphezu koko, iinjineli zihlala ziphepha iikona ezibukhali kunye nemiphetho xa ziphethe izinto ezibuthathaka ezifana nee-silicon wafers. Iiflethi kunye nezikhewu ezijikelezileyo zinciphisa imingxunya okanye ukuqhekeka xa kuthelekiswa nokuphathwa yimiphetho ebukhali.
Iiflethi okanye iinotshi ziphucula uzinzo lokuphatha ngelixa zivula indawo yokwenza izixhobo.
Iiflethi zeWafer vs. iWafer Notch
Zombini iiflethi kunye neenotshi zisebenza indima efanayo ngempumelelo, ngoko kutheni ke zineentlobo ezimbini? Kukho umahluko omncinci...
Iiflethi zithatha indawo engakumbi kumjikelezo kodwa zinendawo yokubamba enkulu nethe tye. Iinotshi zincinci ngakumbi kodwa zibonelela ngendawo yokubamba ekhuselekileyo ye-vertex.
Kukho izizathu zembali ezisekelwe kutshintsho lweshishini. Kwasekuqaleni, iiflethi zazibonelela ngokulula ngesikhombisi sokubona kunye nokufikelela ekubambeni kwiingcali ze-wafer. Njengoko i-automation yayisanda, ii-notches zazinokufihlakala ngaphakathi kwemihlathi ye-end-effector.
Uhlobo luxhomekeke kakhulu kuyilo lwezixhobo kunye neenkcukacha ezivela kubathengisi. Uninzi lwezixhobo zokwenza ngoku zisebenza ngokulula ngeeflethi okanye iinotshi.
Ngoko ke ii-semiconductor fabs zamkela umgangatho ofanelekileyo kunokuba zixutywe kwaye zihambelane. Ezinye izityalo zisebenzisa zonke iiflethi, ezinye zonke ii-notches ukwenza lula izinto zokusebenza.
Njengomvelisi ohamba phambili weewafer, sinokukwazi ukubonelela iiwafers ngeeflat okanye iinotches njengoko abathengi befuna kwimigca yabo yokwenziwa.
Indawo yokuthabatha
Nangona ilula, iiflethi kunye neenotshi zivumela ukuphathwa, ukulungelelaniswa, kunye nokhuseleko ekucutshungulweni kwe-silicon wafer. Ukungalingani kuvumela ukujongwa okungalunganga ngelixa kubonelela ngezixhobo ukufikelela kwii-wafers zokubamba ngaphandle komonakalo kumphezulu.
Ngexesha elizayo xa ujonga isekethe edibeneyo, cinga ngendima ebalulekileyo eyayinayo loo ndlu incinci okanye i-notch ekwenziweni kwayo!
Ngaphandle kwe-flats okanye ii-notches, ii-transistors ze-trillion-plus kwi-silicon bezingenakuze zibe zezona zinto zisebenza kwi-elektroniki yakho yanamhlanje. Esinye isizathu sokuba iinkcukacha ezibonakala zingabalulekanga zibaluleke kakhulu kwimveliso ye-semiconductor!
