Mathata a Metallization ho Ts'ebetso ea Semiconductor le Mokhoa oa ho a rarolla

Ho etsa metallization ke mohato oa bohlokoa ts'ebetsong ea semiconductor, e kenyeletsang ho thehoa ha likhokahano tsa tšepe tse kang koporo kapa aluminium. Leha ho le joalo, litaba tsa ho etsa metallization—haholo-holo ho falla ha motlakase le khanyetso e eketsehileng ea ho kopana—li baka liphephetso tse kholo ts'ebetsong le botšepehing ba lipotoloho tse kopantsoeng.

Lisosa tsa Mathata a Metallization

Mathata a metallization a bakoa haholo-holo ke maemo a sa tloaelehang a mocheso le liphetoho tsa microstructure nakong ea tlhahiso:

1. Mocheso o feteletseng: Nakong ea ho kenngoa ha motlakase mochesong o phahameng, likhokahano tsa tšepe li ka ba le ho falla ha motlakase kapa kholo e feteletseng ea lijo-thollo. Liphetoho tsena tsa sebopeho sa micros li beha thepa ea motlakase kotsing 'me li fokotsa ts'epo ea likhokahano.

2. Mocheso o sa lekaneng: Haeba mocheso o le tlase haholo, khanyetso ea ho kopana pakeng tsa tšepe le silicon e ke ke ea ntlafatsoa, ​​e leng se lebisang phetisong e mpe ea motlakase, tšebeliso e eketsehileng ea matla, le ho se tsitse ha sistimi.

Tšusumetso ho Tshebetso ea Chip

Litlamorao tse kopaneng tsa ho falla ha motlakase, kholo ea lijo-thollo, le khanyetso e eketsehileng ea ho kopana li ka fokotsa ts'ebetso ea chip haholo. Matšoao a kenyelletsa phetiso e liehang ea lets'oao, liphoso tsa logic, le kotsi e kholo ea ho hloleha ha ts'ebetso. Qetellong sena se fella ka litšenyehelo tse eketsehileng tsa tlhokomelo le potoloho ea bophelo ba sehlahisoa e fokotsehileng.

Litharollo tsa Mathata a ho Etsa Metallization

1. Ntlafatso ea Taolo ea Mocheso: Ho kenya tšebetsong taolo e nepahetseng ea mocheso, joalo ka ho sebelisa li-chiller tsa metsi tsa maemo a indasteri , ho thusa ho boloka mocheso o tsitsitseng oa ts'ebetso. Pholiso e tsitsitseng e fokotsa kotsi ea ho falla ha motlakase 'me e ntlafatsa ho hanyetsa ho kopana ha tšepe le silicon, e ntlafatsa ts'ebetso ea chip le ts'epo.

2. Ntlafatso ea Ts'ebetso: Ho lokisa thepa, botenya le mekhoa ea ho beha lera la ho ikopanya ho ka thusa ho fokotsa khanyetso ea ho kopana. Mekhoa e kang meaho e mengata kapa ho sebelisa doping ka likarolo tse itseng e ntlafatsa phallo ea hona joale le botsitso.

3. Khetho ea Thepa: Ho sebelisa litšepe tse nang le khanyetso e phahameng khahlanong le ho falla ha motlakase, joalo ka li-alloy tsa koporo, le thepa ea ho ikopanya e tsamaisang motlakase haholo joalo ka polysilicon e nang le doped kapa silicides tsa tšepe, ho ka fokotsa khanyetso ea ho kopana le ho netefatsa ts'ebetso ea nako e telele.

Qetello

Mathata a metallization tsamaisong ea semiconductor a ka fokotsoa ka katleho ka taolo e tsoetseng pele ea mocheso, tlhahiso e ntlafalitsoeng ea ho ikopanya, le khetho ea thepa ea maano. Litharollo tsena lia hlokahala bakeng sa ho boloka ts'ebetso ea chip, ho atolosa bophelo ba sehlahisoa, le ho netefatsa ho tšepahala ha lisebelisoa tsa semiconductor.
