E 'ngoe-stop Electronic Manufacturing Services, e u thusa ho fumana lihlahisoa tsa hau tsa elektroniki habonolo ho tsoa ho PCB & PCBA

Phahamisa tsebo! Chip e etsa joang? Kajeno qetellong kea utloisisa

Ho ea ka pono ea setsebi, mokhoa oa tlhahiso ea chip o rarahane haholo ebile oa khathatsa. Leha ho le joalo, ho tsoa ho ketane e felletseng ea indasteri ea IC, e arotsoe haholo ka likarolo tse nne: moralo oa IC → tlhahiso ea IC → ho paka → tlhahlobo.

Mokhoa oa ho etsa chip:

1. Moralo oa chip

Chip ke sehlahisoa se nang le molumo o monyenyane empa se nepahetse haholo. Ho etsa chip, moralo ke karolo ea pele. Moralo o hloka thuso ea moralo oa chip oa moralo oa chip o hlokahalang bakeng sa ho sebetsa ka thuso ea sesebelisoa sa EDA le li-cores tse ling tsa IP.

3. Silicon -ho phahamisa

Ka mor'a hore silicon e arohane, lisebelisoa tse setseng li tloheloa. Silicon e hloekileng ka mor'a mehato e mengata e fihlile boleng ba tlhahiso ea semiconductor. Sena ke seo ho thoeng ke silicon ea elektroniki.

4. Silicon -casting ingots

Ka mor'a ho hloekisa, silicon e lokela ho lahleloa ka har'a li-ingots tsa silicon. Kristale e le 'ngoe ea silicon ea boemo ba elektronike ka mor'a ho lahleloa ka har'a ingot e boima ba lik'hilograma tse 100,' me bohloeki ba silicon bo fihla ho 99.9999%.

Ka mor'a hore silicon e lahleloe, ingot eohle ea silicon e tlameha ho khaoloa likotoana, e leng sephaphatha seo re atisang ho se bitsa sephaphatha, se tšesaane haholo. Ka mor'a moo, sephaphatha se belisoa ho fihlela se phethahetse, 'me bokaholimo bo boreleli joalo ka seipone.

Bophara ba li-wafers tsa silicon ke 8-inch (200mm) le 12-inch (300mm) bophara. Ha bophara ba bophara bo le boholo, ho theola litšenyehelo tsa chip e le 'ngoe, empa bothata ba ho sebetsa bo phahame.

7. Eclipse le ente ea ion

Ntlha ea pele, hoa hlokahala ho senya silicon oxide le silicon nitride e pepesitsoeng ka ntle ho photoresist, le ho fokotsa sekhahla sa silicon ho insulate pakeng tsa tube ea kristale, ebe u sebelisa theknoloji ea etching ho pepesa silicon e tlase. Ebe u kenya boron kapa phosphorus mohahong oa silicon, ebe u tlatsa koporo ho kopanya le li-transistors tse ling, ebe u sebelisa lesela le leng la sekhomaretsi ho eona ho etsa lera la sebopeho. Ka kakaretso, chip e na le likarolo tse ngata, joalo ka litsela tse kholo tse lohiloeng.
