Iyini i-coefficient yokwandisa ukushisa kombhede we-granite? Kubaluleke kangakanani lokhu kumadivayisi e-semiconductor?

I-Granite iyindlela ethandwayo yokukhetha amadivayisi e-semiconductor ngenxa yokuqina kwayo okuhle kakhulu kokushisa kanye namandla omshini. I-thermal expansion coefficient (TEC) ye-granite iyisici esibalulekile esinquma ukufaneleka kwayo ukusetshenziswa kulezi zinhlelo zokusebenza.

I-coefficient yokwandisa ukushisa kwe-granite cishe iphakathi kuka-4.5 - 6.5 x 10^-6/K. Lokhu kusho ukuthi kuwo wonke amazinga okushisa e-Celsius, umbhede we-granite uzokhula ngaleli nani. Nakuba lokhu kungase kubonakale njengoshintsho oluncane, kungabangela izinkinga ezinkulu kumadivayisi e-semiconductor uma kungabalwa kahle.

Amadivayisi e-semiconductor azwela kakhulu ekushintsheni kwezinga lokushisa, futhi noma yikuphi ukushintsha okuncane kwezinga lokushisa kungathinta ukusebenza kwawo. Ngakho-ke, kubalulekile ukuthi i-TEC yezinto ezisetshenziswa kulawa madivayisi iphansi futhi ibikezelwe. I-TEC ephansi ye-Granite ivumela ukushabalaliswa kokushisa okuzinzile nokungaguquguquki kusuka kudivayisi, okuqinisekisa ukuthi izinga lokushisa lihlala ngaphakathi kwebanga elifunekayo. Lokhu kubalulekile ngoba ukushisa ngokweqile kungalimaza impahla ye-semiconductor futhi kufinyeze isikhathi sayo sokuphila.

Esinye isici esenza i-granite ibe yinto ekhangayo yombhede wamadivayisi e-semiconductor amandla ayo okusebenza. Amandla ombhede we-granite okubekezelela ukucindezeleka okukhulu nokuhlala uzinzile kubalulekile ngoba amadivayisi e-semiconductor avame ukubhekana nokudlidliza ngokomzimba kanye nokushaqeka. Ukwanda okuhlukahlukene kanye nokufinyela kwezinto ngenxa yokushintshashintsha kwezinga lokushisa nakho kungabangela ukucindezeleka ngaphakathi kwedivayisi, futhi ikhono le-granite lokugcina isimo sayo ngaphansi kwalezi zimo linciphisa ingozi yokulimala kanye nokwehluleka.

Ekuphetheni, i-coefficient yokwandisa ukushisa kombhede we-granite idlala indima ebalulekile ekusebenzeni kwamadivayisi e-semiconductor. Ngokukhetha izinto ezine-TEC ephansi, njenge-granite, abakhiqizi bemishini yokwenza ama-chip bangaqinisekisa ukusebenza okuzinzile kokushisa kanye nokusebenza okuthembekile kwala madivayisi. Yingakho i-granite isetshenziswa kabanzi njengezinto zombhede embonini ye-semiconductor, futhi ukubaluleka kwayo akunakuphikiswana uma kukhulunywa ngokuqinisekisa ikhwalithi kanye nobude besikhathi sala madivayisi.
