Waa maxay Epi Carrier?

Sahaminta Doorkeeda Muhiimka ah ee Habaynta Waferka Epitaxial

Fahamka Muhiimadda Epi Carriers ee Soo saarista Semiconductor Sare

Warshadaha semiconductor-ka, soo saarida wafers-tayada sare leh ee epitaxial (epi) waa tallaabo muhiim u ah qalabka wax soo saarka sida transistor-ka, diodes, iyo qaybaha kale ee elektiroonigga ah. Udub dhexaad u ah geedi socodkan waaEpi side, qalab gaar ah oo loogu talagalay in uu si ammaan ah u xajiyo maraqyada inta lagu jiro kaydinta epitaxial. Laakiin waa maxay dhab ahaan sidaha Epi, iyo sababta ay muhiim ugu tahay wax soo saarka semiconductor?

Kobaca Epitaxial: Geedi socodka Furaha ee Soo saarida Semiconductor

Kobaca Epitaxial, ama epitaxy, waxa loola jeedaa habka lagu shubayo lakab khafiif ah oo walxo crystalline ah oo lagu shubayo maraqa semiconductor. Lakabkaan, oo loo yaqaan lakabka epitaxial, wuxuu leeyahay hanuunin la mid ah kan substrate-ka hoose waxaana loo isticmaalaa in lagu wanajiyo sifooyinka korantada ee waferka. Epitaxy waxay lama huraan u tahay abuurista aaladaha waxqabadka sare leh ee u baahan in si sax ah loo koontaroolo qaab-dhismeedka shay.

Si loo gaaro tayada la doonayo iyo labbiska ee lakabka epitaxial, wafers waa in lagu hayaa meel si sax ah iyo xasilooni inta lagu jiro habka dhigaalka. Tani waa meeshaEpi sideciyaarta soo galay.

Doorka Epi Carrier

An Epi sidewaa qalab si gaar ah loo nashqadeeyay oo xajiya maraqyada inta lagu jiro habka dhigista epitaxial. Waxa sida caadiga ah laga sameeyaa walxo nadiif ah oo u adkeysan kara heerkulka sare iyo jawiga falcelinta ee ku lug leh epitaxy. Naqshadeynta qaaduhu waxay hubisaa in mareegaha ay si ammaan ah u taagan yihiin oo si siman u bannaan yihiin alaabta dhigaalka, taasoo keentay lakabka epitaxial labbiska ah ee dhammaan dusha sare ee waferka.

Mid ka mid ah hawlaha aasaasiga ah ee side epi waa in la ilaaliyo xasilloonida iyo toosinta waferka inta lagu jiro habka dhigista. Dhaqdhaqaaq kasta ama khaladaad kasta ayaa u horseedi kara cilladaha lakabka epitaxial, taas oo si weyn u saameyn karta waxqabadka qalabka semiconductor ee ugu dambeeya. Siduhu waa inuu sidoo kale ka hortagaa wasakhda oo uu xaqiijiyaa in maraqyadu ka xoroobaan walxaha ama wasakhda inta lagu jiro habaynta.

Waa maxay sababta Epi Carriers ay Muhiim ugu yihiin Soo saarista Semiconductor

Tayada lakabka epitaxial wuxuu si toos ah u saameeyaa waxqabadka qalabka semiconductor. Sidan oo kale, doorka Epi side ayaa muhiim u ah gaaritaanka heerarka sare ee looga baahan yahay warshadaha. Iyadoo la siinayo jawi xasiloon oo la xakameeyey oo loogu talagalay farsamaynta waferka, sidaha epitaxial wuxuu hubinayaa in lakabka epitaxial loo dhigo si isku mid ah oo aan cillad lahayn.

Qaadayaasha Epi sidoo kale waa lama huraan si ay u taageeraan miisaanka wax soo saarka semiconductor. Maaddaama joomatariyada aaladaha ay sii yaraanayaan oo ay baahida waxqabadka sare u korto, baahida loo qabo hababka epitaxial ee saxda ah oo la isku halayn karo ayaa sii noqonaya mid aad muhiim u ah. Sidayaal tayo sare leh ayaa ka caawiya soosaarayaasha inay buuxiyaan shuruudahan iyagoo awood u siinaya natiijooyin joogto ah oo la soo saari karo, xitaa marka wax soo saarku kor u kaco.

Gabagabo

Marka la soo koobo, sidaha Epi waa qalab lagama maarmaanka u ah habka wax soo saarka semiconductor, gaar ahaan soo saarista waferrada epitaxial. Doorka ay ku leedahay hubinta xasiloonida wafer-ka, toosinta, iyo xakamaynta faddaraynta ayaa lama huraan u ah gaaritaanka lakabyada epitaxial-ka ee tayada sare leh ee looga baahan yahay aaladaha sarraysa ee semiconductor. Maaddaama warshaduhu ay sii wadaan inay riixaan xudduudaha tignoolajiyada, muhiimada la isku halayn karo oo hufan sidayaal epi ayaa kordhin doona oo kaliya, taasoo ka dhigaysa qayb muhiim ah raadinta heer sare ee soo saarista semiconductor.

Kuwa ku jira warshadaha semiconductor ee raadinaya inay wanaajiyaan hanaankooda epitaxial, fahamka iyo maalgelinta sidayaal tayo sare leh ayaa ah tillaabo muhiim ah oo lagu gaaro natiijooyin wanaagsan iyo ilaalinta geesta tartan ee suuqa.
