1.Chii chinonzi bonding (chip bonding uye bonding)

bonding inzira yekubatanidza mukugadzira chip, inowanzo shandiswa kubatanidza dunhu remukati re chip kumapini epasuru newaya yegoridhe isati yarongedza, uye kazhinji mushure mekubatana (kureva mushure mekunge dhizaini yabatana nemapini) iyo chip ndiyo. yakavharidzirwa nejeli dema uchishandisa iyo yepamusoro yekunze yekurongedza tekinoroji COB (ChipOnBoard), maitiro aya anofanirwa kunge akaedza epitaxial wafer akaiswa muyakakosha redunhu board, ipapo epitaxial wafer circuit yakabatana nedhiketi bhodhi newaya yegoridhe, yobva yanyunguduka. ine basa rinokosha rekudzivirira rezvigadzirwa zvehupenyu zvakafukidzwa ne epitaxial wafers kupedzisa post-encapsulation yechip.

2.Chii chinonzi semiconductor?

Ngatitange nei semiconductor.Kubva pakuona kwezvinhu: semiconductor chinhu chine conductive zvivakwa pakati peiyo conductor uye insulator pakudziya kwekamuri.Senge muhupenyu hwemazuva ese, waya dzemhangura nealuminium ma conductor, nepo rubha nezvimwe zvakadaro zvidziviriri.Panyaya yemagetsi conductivity: semiconductor chinhu chine controlled magetsi conductivity, kubva insulator kusvika conductor.

Zvina zvimiro zvesemiconductors.

Kuwanikwa kwema semiconductors kunogona kurondwa kumashure kusvika 1833, apo Faraday, musayendisiti weBritish, uye baba vemagetsi, ndiye akatanga kuona kuti kushomeka kwesirilfi sulfide kwakasiyana nekupisa kwakasiyana nekwesimbi yakajairwa, yaive yekutanga. kuwanikwa kweiyo semiconductor phenomenon.

Asi pfupiso yezvivakwa zvesemiconductors haina kupera kusvika Zvita 1947 neBell Laboratories.

Kupisa kunokwira, uye kushorwa kunowira: kushorwa kwe semiconductor kunoderera sezvo tembiricha inokwira, asi, kazhinji, kushorwa kwesimbi kunowedzera nekupisa.

Photovoltaic effect: musanganiswa unoumbwa nekusangana pakati pe semiconductor ne electrolyte unoburitsa voltage kana yaiswa pachiedza.

Photoconductive effect: conductivity ye semiconductor inowedzera muhupo hwechiedza.

Rectification effect: iyo conductivity ye semiconductor inotungamira uye ine hukama negwara remunda wemagetsi wakaiswa.Wedzera yakanaka voltage kusvika kumigumo ye semiconductor uye inofambisa;kana iyo voltage polarity ikadzoserwa kumashure, haina kunaka.
