1.Bonding ke eng (chip bonding le bonding)

bonding ke mokhoa oa ho kopanya ts'ebetsong ea tlhahiso ea chip, e atisang ho sebelisoa ho hokahanya potoloho ea ka hare ea chip ho lithapo tsa sephutheloana ka terata ea khauta pele e paka, 'me hangata ka mor'a ho kopanya (ke hore ka mor'a hore potoloho e hokahane le lithapo) e kentsoeng ka gel e ntšo ha e ntse e sebelisa theknoloji e tsoetseng pele ea ho paka ka ntle ea COB (ChipOnBoard), ts'ebetso ena e lokela ho lekola sephaphatha sa epitaxial se kentsoeng ka har'a boto e khethehileng ea potoloho, ebe potoloho ea epitaxial wafer e hokahantsoeng le boto ea potoloho ka terata ea khauta, ebe ea qhibiliha. ka ts'ebetso e khethehileng ea ts'ireletso ea lisebelisoa tsa manyolo tse koahetsoeng ka li-wafers tsa epitaxial ho tlatsa post-encapsulation ea chip.

2.Semiconductor ke eng?

Ha re qale ka hore na semiconductor ke eng.Ho ea ka pono ea lintho tse bonahalang: semiconductor ke thepa e nang le thepa ea conductive pakeng tsa conductor le insulator mocheso oa kamore.Joalo ka bophelo ba letsatsi le letsatsi, lithapo tsa koporo le aluminium ke li-conductor, athe rabara le tse ling ke li-insulators.Mabapi le conductivity ea motlakase: semiconductor ke thepa e nang le motlakase o laoloang, ho tloha ho insulator ho ea ho conductor.

Lintho tse 'nè tsa li-semiconductors.

Ho sibolloa ha li-semiconductors ho ka saloa morao ho fihlela ka 1833, ha Faraday, rasaense oa Brithani, le ntate oa lisebelisoa tsa elektronike, e ne e le eena oa pele oa ho fumana hore khanyetso ea silevera sulfide e fapane le mocheso o fapaneng le oa tšepe e tloaelehileng, eo e neng e le eona ea pele. ho sibolloa ha ketsahalo ea semiconductor.

Empa kakaretso ea thepa ea li-semiconductors ha ea ka ea phethoa ho fihlela ka December 1947 ke Bell Laboratories.

Mocheso oa phahama, 'me ho hanyetsa ho oa: ho hanyetsa ha semiconductor ho fokotseha ha mocheso o ntse o phahama, empa, ka kakaretso, ho hanyetsa tšepe ho eketseha ka mocheso.

Photovoltaic effect: mateano a entsoeng ka ho kopana pakeng tsa semiconductor le electrolyte a hlahisa motlakase ha a pepesehetse khanya.

Photoconductive effect: conductivity ea semiconductor e eketseha ka pel'a leseli.

Phello ea ho lokisa: conductivity ea semiconductor ke tataiso 'me e amana le tataiso ea sebaka sa motlakase se sebelisoang.Eketsa motlakase o motle ho ea lipheletsong tsa semiconductor 'me e khanna;haeba polarity ea motlakase e khutlisetsoa morao, ha e na thuso.
