Kuyini ukuzinza okushisayo kwesisekelo se-granite kumishini ye-semiconductor?

I-Granite uhlobo lwetshe elaziwa ngokuba lukhuni, ukuqina, kanye nokumelana nokugqwala kwamakhemikhali. Ngakho-ke, sekuyisinqumo esidumile sesisekelo semishini ye-semiconductor. Ukuzinza okushisayo kwesisekelo se-granite kungenye yezinto ezikhangayo kakhulu.

Ukuzinza kwe-thermal kusho ikhono lempahla ukumelana noshintsho esakhiweni sayo lapho ibhekene namazinga okushisa aphezulu. Kumongo wempahla ye-semiconductor, kubalulekile ukuthi isisekelo sibe nokuzinza okuphezulu kwe-thermal njengoba okokusebenza kusebenza emazingeni okushisa aphezulu isikhathi eside. I-Granite itholwe inokusimama okuhle kakhulu kwe-thermal, ene-coefficient ephansi ye-thermal expansion (CTE).

I-CTE yento ethile isho inani ubukhulu bayo obushintshayo uma ivezwe ekushintsheni kwezinga lokushisa. I-CTE ephansi isho ukuthi okokusebenza mancane amathuba okuthi kusonteke noma konakale lapho kuvezwe kumazinga okushisa ahlukene. Lokhu kubaluleke kakhulu kusisekelo semishini ye-semiconductor, okudingeka ihlale izinzile futhi isicaba ukuze kuqinisekiswe imiphumela enembile nethembekile.

Uma kuqhathaniswa nezinye izinto ezivame ukusetshenziselwa izisekelo zemishini ye-semiconductor, njenge-aluminium nensimbi engagqwali, i-granite ine-CTE ephansi kakhulu. Lokhu kusho ukuthi ingakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokugoba noma ukonakala. Ukwengeza, i-thermal conductivity ye-granite ivumela ukuthi ikhiphe ukushisa ngokushesha, okungasiza ukugcina izinga lokushisa elizinzile ngesikhathi sokusebenza.

Enye inzuzo yokusebenzisa i-granite njengesisekelo semishini ye-semiconductor ukumelana kwayo nokugqwala kwamakhemikhali. Izinto ezisetshenziswa ekwenziweni kwe-semiconductor ngokuvamile zibandakanya ukusetshenziswa kwamakhemikhali anokhahlo, angagqwala futhi alimaze isisekelo. Ukumelana kwe-granite nokugqwala kwamakhemikhali kusho ukuthi ingakwazi ukumelana nokuchayeka kulawa makhemikhali ngaphandle kokuwohloka.

Sengiphetha, ukuzinza okushisayo kwegwadle kuyisici esibalulekile sesisekelo semishini ye-semiconductor. I-CTE yayo ephansi, i-thermal conductivity ephezulu, kanye nokumelana nokugqwala kwamakhemikhali kuyenza ibe yinto efanelekile yale njongo. Ngokusebenzisa i-granite njengesisekelo, abakhiqizi be-semiconductor bangaqinisekisa ukuzinza nokunemba kwemishini yabo, okuholela emikhiqizweni yekhwalithi ephezulu kanye nokusebenza kahle okwandisiwe.
