Iyini ithreyi ye-silicon carbide

Amathreyi e-silicon carbide, eyaziwa nangokuthi amathreyi e-SiC, yizinto ezibalulekile ezisetshenziselwa ukuthwala ama-wafers e-silicon enqubweni yokukhiqiza ye-semiconductor. I-Silicon carbide inezakhiwo ezinhle kakhulu njengokuqina okuphezulu, ukumelana nokushisa okuphezulu, nokumelana nokugqwala, ngakho-ke ishintsha kancane kancane izinto zendabuko ezifana ne-quartz namathreyi e-ceramic embonini ye-semiconductor. Ngokuthuthuka kwemboni ye-semiconductor, ikakhulukazi emikhakheni ye-5G, amadivaysi e-optoelectronic, amandla kagesi, njll., isidingo samathreyi e-silicon carbide nawo siyakhula.

I-Semiceraamathreyi e-silicon carbidesebenzisa izinqubo ezithuthukisiwe ze-sintering phakathi nenqubo yokukhiqiza ukuze kuqinisekiswe ukuminyana okuphezulu namandla amathreyi, okubenza bakwazi ukugcina ukusebenza okuzinzile ngaphansi kwezimo ezinzima ezifana nokushisa okuphezulu nokucindezela okukhulu. Ngesikhathi esifanayo, i-coefficient ephansi yokwandisa okushisayo kwamathreyi e-silicon carbide inganciphisa umthelela wokushintsha kwezinga lokushisa ekucubunguleni ukunemba.izinkwa ze-silicon, ngaleyo ndlela kuthuthukiswe izinga lokukhiqiza lemikhiqizo.

Iamathreyi e-silicon carbideeyakhiwe yi-Semicera ayifanele kuphela ukucutshungulwa kwendabukoizinkwa ze-silicon, kodwa futhi ingasetshenziswa ekwenzeni ama-silicon carbide wafers, okubalulekile ekuthuthukisweni kwesikhathi esizayo kwemboni ye-semiconductor. Ama-wafers e-silicon carbide anokuhamba kwama-electron aphezulu kanye nokuhamba okungcono kwe-thermal, okungathuthukisa kakhulu ukusebenza kahle nokusebenza kwamadivayisi. Ngakho-ke, isidingo samathreyi e-silicon carbide alungele ukukhiqizwa kwawo siyakhuphuka.

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza i-semiconductor, inqubo yokuklama kanye nokukhiqizwa kwamathreyi e-silicon carbide nawo ayathuthukiswa. Ngokuzayo, i-Semicera izoqhubeka nokusebenza ekuthuthukiseni ukusebenza kwe-silicon carbide pallets ukuze ihlangabezane nesidingo semakethe sokunemba okuphezulu, ama-pallets athembeke kakhulu. Ukusetshenziswa kabanzi kwe-silicon carbide pallets akugcini nje ukukhuthaza ukuthuthukiswa kwezinqubo zokukhiqiza i-semiconductor, kodwa futhi kunikeza ukwesekwa okuqinile kokugcwaliseka kwemikhiqizo kagesi esebenza kahle futhi ezinzile.
