Chii chinonzi kugadzikana kwekupisa kwechigadziko chegranite mumidziyo yesemiconductor?

Granite idombo rinozivikanwa nekuoma kwayo, kugara kwenguva refu, uye kuramba ngura yemakemikari. Saka, rave sarudzo yakakurumbira yemidziyo ye semiconductor. Kugadzikana kwekupisa kwechigadziko chegranite chimwe chezvinhu zvinokwezva.

Kugadzikana kwekupisa kunoreva kugona kwechinhu kuramba shanduko muchimiro chacho kana chaiswa pakupisa kwakanyanya. Panyaya yemidziyo ye semiconductor, zvakakosha kuti hwaro huve nekugadzikana kwakanyanya kwekupisa sezvo michina ichishanda pakupisa kwakanyanya kwenguva yakareba. Granite yakawanikwa ine kugadzikana kwakanaka kwekupisa, ine coefficient yakaderera yekuwedzera kwekupisa (CTE).

CTE yezvinhu zvinoreva huwandu hunochinja saizi yazvo kana zvasangana nekuchinja kwekupisa. CTE yakaderera zvinoreva kuti zvinhu zvacho hazviwanzo kupetana kana kukanganisika kana zvasangana nekupisa kwakasiyana. Izvi zvakakosha zvikuru kune base yemidziyo ye semiconductor, iyo inofanirwa kuramba yakagadzikana uye yakati sandara kuti ive nechokwadi chekuti mhedzisiro yakarurama uye yakavimbika.

Zvichienzaniswa nezvimwe zvinhu zvinowanzoshandiswa pakugadzira mabhesi emidziyo ye semiconductor, zvakaita searuminiyamu nesimbi isingatsvi, granite ine CTE yakaderera zvikuru. Izvi zvinoreva kuti inogona kutsungirira tembiricha yakakwira isina kuchinjika kana kukanganisika. Pamusoro pezvo, thermal conductivity yegranite inoita kuti ibvise kupisa nekukurumidza, izvo zvinogona kubatsira kuchengetedza tembiricha yakagadzikana panguva yekushanda.

Imwe mukana wekushandisa granite sehwaro hwemidziyo ye semiconductor ndeyekudzivirira kwayo ngura yemakemikari. Midziyo inoshandiswa mukugadzira semiconductor inowanzo sanganisira kushandiswa kwemakemikari ane simba, anogona ngura nekukuvadza hwaro. Kudzivirira kwegranite ngura yemakemikari zvinoreva kuti inogona kutsungirira kusangana nemakemikari aya pasina kuora.

Mukupedzisa, kugadzikana kwekupisa kwegranite chinhu chakakosha pahwaro hwemidziyo yesemiconductor. Kuderera kwayo kweCTE, kupisa kwakanyanya, uye kuramba ngura yemakemikari zvinoita kuti ive chinhu chakanakira chinangwa ichi. Nekushandisa granite sehwaro, vagadziri vesemiconductor vanogona kuve nechokwadi chekugadzikana uye kururama kwemidziyo yavo, zvichikonzera zvigadzirwa zvemhando yepamusoro uye kushanda zvakanaka kwakawedzerwa.
