Khethollo ea likhase tse tloaelehileng ho indasteri ea semiconductor

Khase e tloaelehileng

Khase e tloaelehileng e boetse e bitsoa khase ea bongata: e bua ka khase ea indasteri e nang le tlhoko ea sesupo se ka tlase ho 5n le molumo o moholo oa ho rekisa. E ka aroloa hore e be khase ea ho arohana le khase ea maiketsetso le khase ea maiketsetso ho latela mekhoa e fapaneng ea ho lokisa. Fydrogen (H2), Netrojene (N2), oksijene (O2), Argon (A2), jj.;

Khase e ikhethang

Khase e khethehileng e bua ka khase e sebelisetsoang ho sebelisoa masimong a bohloeki ebile e na le lintho tse ikhethang bakeng sa bohloeki, mefuta e fapaneng le thepa.

Mefuta ea likhase tsa Spania

Mefuta ea likhase tse khethehileng: ho na le chefo, chefo, ho ts'ehetsa, ho ts'ehetsa, Intert, entc.
Hangata likhase tse sebelisetsoang li-couse tsa semiconductor li khethollotsoe ka tsela e latelang:

Ho tsoa likarolong tse ka holimo, re ka utloisisa hore likhase tse ngata tsa semysondtor li kotsi ho 'mele oa motho. Ka ho khetheha, likhase tse ling tse kang Sih4, li itšehla thajana. Ha feela ba tsoa, ​​ba tla etsa hore ba be le oknoloji moeeng 'me ba qala ho chesa; mme Ash3 e na le chefo e ngata. Ho fafatsa hanyane ho ka baka ho utloisa mapheting a batho, kahoo litlhoko tsa polokeho ea moralo oa tsamaiso ea lits'oants'o tse khethehileng li phahame haholo.

Li-semiconductors li hloka likhase tse phahameng tsa bohloeki hore li be le "likhato tse tharo"

Pure ea gas

The content of impurity atmosphere in the gas is usually expressed as a percentage of gas purity, such as 99.9999%. Ka kakaretso, Tlhokahalo ea bohloeki bakeng sa likhase tse khethehileng tsa elektroniki e fihla ho 5n-6n, 'me e boetse e hlahisoa ke likhakanyo tsa bophahamo ba PPM (karolo e ngoe le e ngoe). Tšimo ea Sehamicusctor e na le litlhokahalo tse ngata bakeng sa bohloeki le botsitso ba boleng ba likhase tse khethehileng, le bohloeki ba likhase tse khethehileng tsa elektroniki li seholo ho feta 6n.
