1. Molao-motheo oa kopo le phello ea 6N purity crystalline boron phofo ka tlhahiso ea silicon ingot
Silicon (Si), e le thepa ea motheo ea indasteri ea semiconductor, e sebelisoa haholo lipotolohong tse kopanetsoeng (ICs) le lisele tsa letsatsi. E le ho ntlafatsa conductivity ea silicon, hangata ho hlokahala ho fetola thepa ea eona ea motlakase ka doping le likarolo tse ling.Boron (B) ke e 'ngoe ea lintho tse sebelisoang haholo ho sebelisa doping. E ka khona ho lokisa conductivity ea silicon ka katleho le ho laola p-type (positive) semiconductor thepa ea thepa ea silicon. Ts'ebetso ea boron doping hangata e etsahala nakong ea kholo ea li-ingots tsa silicon. Motsoako oa liathomo tsa boron le likristale tsa silicon li ka theha thepa e ntle ea motlakase ka har'a likristale tsa silicon.
E le mohloli oa doping, 6N (99.999999%) phofo e hloekileng ea crystalline boron e na le bohloeki bo phahameng ka ho fetisisa le botsitso, bo ka netefatsang hore ha ho na litšila tse hlahisoang nakong ea tlhahiso ea silicon ingot ho qoba ho ama boleng ba khōlo ea kristale. Phofo e phahameng ea boron e ka laola ka mokhoa o nepahetseng motsoako oa doping oa likristale tsa silicon, kahoo o finyella ts'ebetso e phahameng ea tlhahiso ea li-chip, haholo-holo lipotolohong tse kopantsoeng tse phahameng le lisele tsa letsatsi tse sebetsang hantle tse hlokang taolo e nepahetseng ea thepa ea motlakase.
Tšebeliso ea phofo e phahameng ea boron e ka qoba ka katleho tšusumetso e mpe ea litšila ts'ebetsong ea li-ingots tsa silicon nakong ea ts'ebetso ea doping le ho ntlafatsa thepa ea motlakase, ea mocheso le ea optical ea kristale. Lisebelisoa tsa silicon tse entsoeng ka boron li ka fana ka motsamao o phahameng oa elektronike, bokhoni bo ntlafetseng ba ho tsamaisa hona joale, le ts'ebetso e tsitsitseng ha mocheso o fetoha, e leng ntho ea bohlokoa ho tšepahala le ts'ebetsong ea lisebelisoa tsa morao-rao tsa semiconductor.
2. Melemo ea China e phahameng-hloeka crystalline boron phofo
