Chii chinonzi thermal expansion coefficient yegranite bed? Izvi zvakakosha sei kumidziyo ye semiconductor?

Granite isarudzo yakakurumbira yemidziyo ye semiconductor nekuda kwekugadzikana kwayo kwakanyanya kwekupisa uye simba remakanika. Iyo thermal expansion coefficient (TEC) yegranite chinhu chakakosha chinosarudza kukodzera kwayo kushandiswa mukushandisa uku.

Kuwanda kwemafuta egranite mukuwedzera kwekushisa kuri pakati pe4.5 - 6.5 x 10^-6/K. Izvi zvinoreva kuti pakuwedzera kwetembiricha kwega kwega kwedhigirii Celsius, mubhedha wegranite uchawedzera nehuwandu uhu. Kunyange zvazvo izvi zvingaita sekuchinja kudiki, zvinogona kukonzera matambudziko makuru mumidziyo yesemiconductor kana zvikasatsanangurwa nemazvo.

Midziyo yeSemiconductor inonzwa zvakanyanya kana tembiricha yachinja, uye chero shanduko diki mutembiricha inogona kukanganisa mashandiro ayo. Saka, zvakakosha kuti TEC yezvinhu zvinoshandiswa mumidziyo iyi ive yakaderera uye inogoneka kufanotaurwa. TEC yakaderera yeGranite inobvumira kupisa kwakasimba uye kwakafanana kubva mumudziyo, zvichiita kuti tembiricha irambe iri mukati mehuwandu hwainodiwa. Izvi zvakakosha nekuti kupisa kwakanyanya kunogona kukuvadza zvinhu zve semiconductor uye kupfupisa hupenyu hwayo.

Chimwe chinhu chinoita kuti granite ive chinhu chinokwezva mubhedha wemidziyo ye semiconductor isimba rayo remakanika. Kugona kwemubhedha we granite kutsungirira kushushikana kukuru uye kuramba wakasimba kwakakosha nekuti michina ye semiconductor inowanzo kanganiswa nekuvhunduka. Kukura kwakasiyana-siyana uye kudzikira kwezvinhu nekuda kwekuchinja-chinja kwekushisa kunogonawo kukonzera kushushikana mukati memudziyo, uye kugona kwegranite kuchengetedza chimiro chayo mumamiriro ezvinhu aya kunoderedza njodzi yekukuvara nekukundikana.

Mukupedzisa, chiyero chekuwedzera kwekupisa kwemubhedha wegranite chinoita basa rakakosha mukushanda kwemidziyo yesemiconductor. Nekusarudza chinhu chine TEC yakaderera, senge granite, vagadziri vemidziyo yekugadzira machipisi vanogona kuve nechokwadi chekuti kupisa kwakasimba uye mashandiro akavimbika emidziyo iyi. Ndokusaka granite ichishandiswa zvakanyanya semidziyo yemubhedha muindasitiri yesemiconductor, uye kukosha kwayo hakugone kupfuudzwa zvakanyanya kana zvasvika pakuona kuti michina iyi inogara kwenguva refu uye ine mhando.
