Kev lag luam semiconductor yog kev lag luam tshiab hauv kev tshawb fawb thiab thev naus laus zis, uas tau nyiam kev saib xyuas zoo hauv xyoo tas los no, ntau lub tuam txhab tau pib nkag mus rau hauv kev lag luam semiconductor, thiab graphite tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb rau kev txhim kho kev lag luam semiconductor. Cov neeg ua haujlwm semiconductor yuav tsum siv cov hluav taws xob conductivity ntawm graphite, vim tias cov pa roj carbon ntau dua ntawm graphite, qhov hluav taws xob conductivity zoo dua, feem ntau yuav tsum xav txog cov ntsuas yog: qhov loj me ntawm cov khoom me me, tiv taus cua sov, thiab kev huv.
Qhov loj ntawm cov noob sib raug rau cov lej mesh sib txawv, thiab cov lus qhia tshwj xeeb tau qhia ua cov lej mesh. Tus lej mesh yog tus lej ntawm cov qhov, uas yog, tus lej ntawm cov qhov ib square inch. Feem ntau hais lus, tus lej mesh * qhov aperture (micron) = 15000. Tus lej mesh loj dua ntawm cov graphite conductive, qhov me dua ntawm cov khoom me me, qhov kev ua haujlwm zoo dua ntawm kev ua kom lubrication, tuaj yeem siv rau hauv kev tsim cov khoom siv lubricating. Qhov loj ntawm cov khoom siv hauv kev lag luam semiconductor yuav tsum zoo heev, vim tias nws yooj yim dua los ua kom tiav qhov kev ua tiav, lub zog compressive siab, thiab kev poob me me, tshwj xeeb tshaj yog rau cov pwm sintering, xav tau qhov tseeb ua tiav siab.
Kev faib tawm qhov loj ntawm cov khoom me me, xws li: 20 mesh, 40 mesh, 80 mesh, 100 mesh, 200 mesh, 320 mesh, 500 mesh, 800 mesh, 1200 mesh, 2000 mesh, 3000 mesh, 5000 mesh, 8000 mesh, 12500 mesh, qhov zoo tshaj plaws tuaj yeem yog 15,000 mesh.
Ntau yam khoom hauv kev lag luam semiconductor yuav tsum tau ua kom sov tas li, txhawm rau kom ntev lub neej kev pabcuam ntawm lub cuab yeej, uas xav tau cov graphite conductive kom muaj cov yam ntxwv hauv qab no: kev ntseeg tau zoo heev thiab kev tiv taus kub siab.
Cov kev cai rau kev tsim graphite hauv kev lag luam semiconductor yog: qhov siab dua qhov purity, qhov zoo dua, tshwj xeeb tshaj yog cov khoom siv graphite uas kov ntawm ob qho tib si, yog tias lawv muaj ntau yam impurities, lawv yuav ua rau cov khoom siv semiconductor qias neeg. Yog li ntawd, peb yuav tsum tswj hwm qhov purity ntawm conductive graphite, thiab peb kuj yuav tsum kho lawv nrog kev kub siab graphitization kom txo qis qib grey.
