Ithini i-coefficient yokwandisa ubushushu bebhedi yegranite? Ibaluleke kangakanani le nto kwizixhobo ze-semiconductor?

I-granite lukhetho oludumileyo kwizixhobo ze-semiconductor ngenxa yozinzo lwayo oluhle kakhulu lobushushu kunye namandla oomatshini. I-thermal expansion coefficient (TEC) ye-granite yipropati ebalulekileyo ebonakalayo egqiba ukuba ifanelekile na ukusetyenziswa kwezi zicelo.

I-coefficient yokwandisa ubushushu begranite imalunga ne-4.5 - 6.5 x 10^-6/K. Oku kuthetha ukuba kwiqondo ngalinye lokunyuka kobushushu beCelsius, ibhedi yegranite iya kwanda ngolu hlobo. Nangona oku kunokubonakala ngathi lutshintsho oluncinci, kunokubangela iingxaki ezinkulu kwizixhobo ze-semiconductor ukuba azibalwanga kakuhle.

Izixhobo ze-semiconductor zinovelwano kakhulu kutshintsho lobushushu, kwaye naluphi na utshintsho oluncinci kubushushu lunokuchaphazela ukusebenza kwazo. Ke ngoko, kubalulekile ukuba i-TEC yezinto ezisetyenziswa kwezi zixhobo iphantsi kwaye iqikeleleke. I-TEC ephantsi yeGranite ivumela ukuchithwa kobushushu okuzinzileyo nokungaguquguqukiyo kwisixhobo, ukuqinisekisa ukuba ubushushu buhlala ngaphakathi koluhlu olufunekayo. Oku kubalulekile kuba ubushushu obugqithisileyo bunokonakalisa izinto ze-semiconductor kwaye bunciphise ubomi bazo.

Enye into eyenza igranite ibe yinto ekhangayo kwibhedi yezixhobo ze-semiconductor ngamandla ayo oomatshini. Amandla ebhedi yegranite okumelana noxinzelelo olukhulu kwaye ahlale ezinzile abalulekile kuba izixhobo ze-semiconductor zihlala ziphantsi kokungcangcazela kunye nokukhwankqiswa. Ukwanda okuhlukeneyo kunye nokuncitshiswa kwezinto ngenxa yokuguquguquka kobushushu kunokubangela uxinzelelo ngaphakathi kwesixhobo, kwaye amandla egranite okugcina imo yayo phantsi kwezi meko anciphisa umngcipheko wokonakala kunye nokungaphumeleli.

Ukuqukumbela, i-coefficient yokwandisa ubushushu bebhedi yegranite idlala indima ebalulekileyo ekusebenzeni kwezixhobo ze-semiconductor. Ngokukhetha izinto ezine-TEC ephantsi, njengegranite, abavelisi bezixhobo zokwenza iitshiphusi banokuqinisekisa ukusebenza okuzinzileyo kobushushu kunye nokusebenza okuthembekileyo kwezi zixhobo. Yingakho igranite isetyenziswa kakhulu njengezinto zebhedi kwishishini le-semiconductor, kwaye ukubaluleka kwayo akunakugqithiswa xa kufikwa ekuqinisekiseni umgangatho kunye nobude bexesha lale zixhobo.
