Ukuqonda kunye nokusebenzisa i-Silicon ye-FE

Esi sikhokelo sibanzi siphonononga ihlabathi le-silicon ye-front-end (FE), egubungela iipropati zayo, izicelo, kunye neziphumo zexesha elizayo. Singena kwiinkqubo zokuvelisa, izikhombisi eziphambili zokusebenza, kwaye sithelekise iintlobo ezahlukeneyo ze I-silicon ye-FE, inika ulwazi kwiingcali kunye nabanomdla ngokufanayo. Funda malunga nenkqubela phambili yokuqhubela izinto ezintsha kule teknoloji ibalulekileyo ye-semiconductor.

Yintoni i-Front-End (FE) Silicon?

I-silicon ye-FE ibhekisa kumanqanaba okuqala okwenziwa kwe-silicon wafer. Iquka iinkqubo ezifana nokukhula kwekristale, ukunqunyulwa kwe-wafer, ukukrazula, ukupolisha, kunye ne-etching. La manyathelo abalulekile ekudaleni umgangatho ophezulu, ii-silicon substrates ezingenasiphako eziyimfuneko kwiisekethe ezidibeneyo (ICs). Umgangatho we I-silicon ye-FE Ichaphazela ngokuthe ngqo ukusebenza kunye nokuthembeka kwezixhobo zokugqibela zombane. Ukwahluka kobunyulu, ubume bekristale, kunye nokugqiba komphezulu kunempembelelo enkulu kwiimpawu zesixhobo.

Iimpawu eziphambili kunye neempawu ze-FE Silicon

Iipropati ezininzi eziphambili ziyalela ukufaneleka kwe I-silicon ye-FE kwizicelo ezahlukeneyo:

• Ukuqhelaniswa neCrystal: I-orientation ye-silicon crystal lattice ichaphazela iimpawu zombane kunye nezomatshini zesixhobo sokugqibela. Uqhelaniso oluqhelekileyo lubandakanya (100) kunye (111).
• Ukuxhathisa: I-resistantivity ye-silicon imisela amandla ayo okuqhuba umbane. Oku kubalulekile ekumiseleni amanqanaba e-doping afunekayo ngexesha leenkqubo ze-backend.
• Umgangatho womphezulu: Umphezulu ogudileyo, ongenasiphako ubalulekile ekusebenzeni kakuhle kwesixhobo. Uburhabaxa bomphezulu kunye neziphene kunokukhokelela ekunciphiseni isivuno kunye nezixhobo ezingathembekanga.
• Ukutyeba kunye nobubanzi: Ubukhulu kunye nobubanzi beewafers ze-silicon zilungelelaniswa ukuququzelela iinkqubo ezifanelekileyo zokuvelisa. Ubukhulu obuqhelekileyo bubandakanya i-200mm, i-300mm, kunye nangaphezulu.

Usetyenziso lwe-FE Silicon

Umgangatho ophezulu I-silicon ye-FE sisiseko soluhlu olukhulu lwezixhobo zombane:

• Microprocessors: Iingqondo zeekhompyuter kunye nee-smartphones zixhomekeke kubuchwephesha obumangalisayo I-silicon ye-FE substrates.
• IiChips zeMemori: Ukusuka kwi-RAM ukuya kugcino lweflash, ukusebenza kunye nomthamo wezixhobo zememori zinxulunyaniswa kumgangatho we I-silicon ye-FE esetyenzisiweyo.
• Iinzwa: Izinzwa ezahlukeneyo, ukusuka kwezo zifunyenwe kwiimoto ukuya kwezo zisetyenziswa kwizixhobo zonyango, zinyusa iipropathi zokucutshungulwa ngononophelo. I-silicon ye-FE.
• Umbane woMbane: Ulawulo lwamandla e-ICs kunye namanye amacandelo afuna umgangatho ophezulu I-silicon ye-FE ekwaziyo ukumelana nemisinga ephezulu kunye nombane.

Ukuthelekiswa kweentlobo ezahlukeneyo ze-Silicon ze-FE

Iinkqubo ezahlukeneyo zokwenziwa kunye neenkcukacha zikhokelela kumanqanaba ahlukeneyo I-silicon ye-FE. Lo mahluko uchaphazela iindleko kunye nokusebenza.

Qaphela: Olu luthelekiso olwenziwe lula. Izicaciso ezizizo ziyahluka kakhulu ngokusekwe kumvelisi kunye neemfuno zesicelo.

Ikamva le-FE Silicon

Uphando oluqhubekayo kunye nophuhliso luqhubeka luphucula umgangatho kunye nobuchule be I-silicon ye-FE. Ukuqhubela phambili kubuchule bokukhula kwekristale, iindlela zonyango lomphezulu, kunye nolawulo lwesiphene zithembisa ukusebenza okuphezulu kunye neendleko eziphantsi. Phonononga izinto ezinokwenzeka ze I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd yomgangatho ophezulu I-silicon ye-FE izisombululo.

Utshintsho oluya kwii-wafers ezinkulu zedayamitha, amanqanaba aphuculweyo okucoceka, kunye neendlela zokwenza inoveli ziqhuba ikamva le I-silicon ye-FE kunye nokusetyenziswa kwayo kwizinto zombane ezikumgangatho ophezulu.
