Kungani Ama-Silicon Wafers Ene-Flats Noma I-Notch?

Ama-wafer e-silicon, isisekelo samasekethe ahlanganisiwe namadivayisi e-semiconductor, eza nesici esithakazelisayo - unqenqema oluyisicaba noma i-notch encane esikiwe ohlangothini. Le mininingwane emincane empeleni isebenzela injongo ebalulekile yokuphatha ama-wafer kanye nokwenza amadivayisi. Njengomkhiqizi we-wafer ohamba phambili, sibuzwa njalo - kungani ama-wafer e-silicon ene-flat noma i-notches? Kulesi sihloko, sizochaza umsebenzi wama-flat nama-notches futhi sixoxe ngomehluko obalulekile.

*Ufuna ama-wafer anezimbobo noma i-notch? Sinezinhlobonhlobo zama-wafer e-silicon ajwayelekile nangokwezifiso atholakalayo ukuze u-ode ku-inthanethi nge-WaferPro - anezimbobo ezijwayelekile ze-SEMI, izimbobo, kanye nezimbobo ezenziwe ngokwezifiso ezifanela izidingo zakho ze-silicon.

Indima Yamafulethi Nama-Notches

Ama-wafer e-silicon athambile futhi kumele aphathwe ngokunemba ngesikhathi sokukhiqiza amadivayisi. Ama-flat nama-notches anikeza indawo lapho imishini ibamba khona i-wafer ngokuphephile ngaphandle kokuthinta izindawo eziyinhloko. Lokhu kuvikela indawo ye-wafer ebalulekile kunoma yimuphi umonakalo noma ukungcola ngesikhathi sokucubungula.

Kunezinhlobo ezimbili eziyinhloko ezisetshenziswa embonini ye-semiconductor:

• Amafulethi - lawa amaphethelo aqondile asikwe ohlangothini lwe-wafer eyindilinga
• Ama-notches - ama-indents amancane anomumo ongu-V emngceleni we-wafer

Imishini ephatha ama-wafer e-silicon ineziphene eziklanyelwe ngqo ukubamba ama-flat noma ama-notches ngokuqinile ukuze athuthwe futhi aqondaniswe emishinini yokukhiqiza. Indawo yokubamba igcinwa incane kakhulu ukuze kuvunyelwe indawo ephezulu yokwakha izifunda ezihlanganisiwe.

Lokhu kuvumela ukunyakaza okuzenzakalelayo nokuphephile kwama-wafer phakathi kwemishini yokucubungula emigqeni yendwangu. Abaqhubi bangaphatha ngokucophelela ama-wafer ngesandla ngama-flat/notches lapho belayisha noma bekhipha ezitsheni zekhasethi.

Kungani Unezicabha Nezimbobo?

Ukungalingani kwe-flat noma i-notch kusebenza umsebenzi obalulekile wokulinganisa ekwenzeni i-wafer. Ngaphandle kwalokhu, bekungeke kube khona indlela yokuqondisa i-wafer ngokuthembekile nokuthola izindawo zokudaya.

Ukuqondanisa Nokumamephu

Amakristalu e-silicon wafer anezakhiwo zama-athomu ezihambisana nezindiza ezithile kanye neziqondiso - kubaluleke kakhulu ukuthi i-wafer ijikeleziswa kanjani!

Ama-flat kanye nama-notches asetshenziswa ukusungula ukuqondiswa kwalezi zindiza zekristalu kanye nama-axes. Njengoba i-asymmetry isendaweni ezungezile, onjiniyela bangaqondanisa ngokunembile neziqondiso zekristalu ezingaphansi kuka-110> noma ngaphansi kuka-100> ezidingekayo.

Lokhu kulungiswa kokuqondisa kuqinisekisa ukumepha okufanele kusukela kumadivayisi e-wafer kuya kumadivayisi okugcina e-chip. Amamaski nemishini kuhlose izindawo ezithile kulo lonke ubuso be-wafer ukuze kwakhiwe izakhiwo namasekethe ahlanganisiwe. Ukungalungi kahle kungenza la madivayisi angasebenzi!

Ukuphatha Nokuphepha

Njengoba sekushiwo kakade, ukuma kwamafulethi/ama-notch kuvumela ukuphathwa okuphephile yimishini yokukhiqiza. Ngaphandle kwalezi zindawo zokubamba, ithuluzi lingabeka amandla angalawuleki kanye nezindawo zokuthintana ze-wafer.

Ukuthintana okunjalo kuyingozi yokungcola okonakele ukusebenza. Izindawo zokubamba ezizungeze umngcele zigwema lokhu kungcola kuyilapho zivikela kangcono i-wafer.

Ngaphezu kwalokho, onjiniyela bavame ukugwema amakhona abukhali kanye nemiphetho lapho bephatha izinto ezibuthakathaka njenge-silicon wafers. Izicaba kanye nezimbobo eziyindilinga kunciphisa imifantu noma ukuphuka uma kuqhathaniswa nokuphathwa yimiphetho ebukhali.

Amafulethi noma ama-notches akhulisa ukuzinza kokuphatha ngenkathi evula isikhala sokwenziwa kwedivayisi.

Amafulethi e-Wafer vs. i-Wafer Notch

Zombili izicaba kanye nezinotshi zisebenza kahle indima efanayo, pho kungani kunezinhlobo ezimbili? Kunezinhlobo ezithile ezicashile...

Amafulethi athatha isikhala esiningi kumjikelezo kodwa anendawo yokubamba enkulu neqondile. Ama-notches mancane kakhulu kodwa ahlinzeka ngendawo yokubamba evikelekile ye-vertex.

Kunezizathu zomlando ezisekelwe ekuguqukeni komkhakha. Ekuqaleni, amafulethi ahlinzeka ngesibonakaliso esibonakalayo esilula kanye nokufinyelela kokubamba kochwepheshe be-wafer. Njengoba ukwenza ngokuzenzakalelayo kwanda, izimbobo zazifihlwa ngaphakathi kwemihlathi ye-end-effector.

Uhlobo luncike kakhulu ekwakhiweni kwemishini kanye nemininingwane evela kubathengisi. Amathuluzi amaningi okukhiqiza manje asebenza kalula ngamafulethi noma ama-notches.

Ngakho-ke i-semiconductor fabs isebenzisa indinganiso efanelana kahle kakhulu kunokuxuba nokufanisa. Ezinye izitshalo zisebenzisa zonke izinhlobo ezifulethi, ezinye zonke izinhlobo ukuze kube lula ukuthutha.

Njengomkhiqizi ohamba phambili wama-wafer, sinekhono lokuhlinzeka ngama-wafer anezicaba noma ama-notches njengoba amakhasimende edinga ngemigqa yawo yokwenziwa.

I-Takeaway

Nakuba kuyisici esincane, ama-flat nama-notches avumela ukuphathwa, ukuhambisana, kanye nokuphepha kokucubungula i-silicon wafer. Ukungalingani kuvumela ukuqondiswa okungaqondakali ngenkathi kunikeza imishini ukufinyelela kuma-wafer abambayo ngaphandle kokulimala kwendawo.

Ngesikhathi esizayo uma ubheka isekethe ehlanganisiwe, cabanga ngendima ebalulekile i-flat noma i-notch encane kangaka eyaba nayo ekwakhiweni kwayo!

Ngaphandle kwama-flat noma ama-notches, ama-transistors e-trillion-plus ku-silicon abengeke afinyelele ku-electronics yakho yesimanje esebenza kahle. Esinye isizathu esenza imininingwane ebonakala ingabalulekile ibaluleke kakhulu ekukhiqizweni kwe-semiconductor!
