Cov Ntawv Thov Alumina Ceramics hauv Kev Tsim Khoom Semiconductor

Alumina ceramics hauv kev tsim khoom semiconductor ua lub luag haujlwm tseem ceeb, nws daim ntawv thov feem ntau yog pom tseeb hauv cov hauv qab no:

Ua ntej,Daim ntawv thov hauvkev ntim khoom siv

Alumina ceramics muaj cov thermal conductivity siab, hluav taws xob rwb thaiv tsev zoo thiab muaj zog siab, ua rau nws yog cov khoom siv zoo tagnrho rau kev ntim khoom siv semiconductor. Tshwj xeeb:

1. Kev ua tau zoo ntawm cov cua sov: cov khoom siv alumina ceramic tuaj yeem txhim kho kev ua haujlwm thermal ntawm lub cuab yeej, txo kev siv hluav taws xob, yog li txhim kho kev ruaj khov thiab kev ntseeg siab ntawm cov khoom siv semiconductor.

2. Kev rwb thaiv hluav taws xob: alumina ceramics yog ib qho khoom rwb thaiv hluav taws xob zoo heev, tuaj yeem tiv taus tam sim no siab heev, zoo tiv thaiv cov khoom siv semiconductor los ntawm hluav taws xob poob siab lossis luv luv thiab lwm yam kev ua tsis tiav.

3. Lub zog siab: alumina ceramics muaj qhov nyuaj heev, Mohs hardness ntawm 9, thib ob tsuas yog pob zeb diamond, ua rau nws tiv taus qhov siab dua thiab cuam tshuam muaj kev tiv thaiv siab rau kev tawg.

Tsis tas li ntawd xwb, tus coefficient ntawm thermal expansion ntawm alumina ceramics yog ze rau silicon (Si), uas yog qhov zoo rau kev txo cov thermal stress thiab txhim kho kev ruaj khov ntawm lub cuab yeej.

Qhov thib ob,Daim ntawv thov hauvcov khoom siv substrate

Alumina ceramic substrates kuj tseem siv dav hauv kev tsim khoom semiconductor. , Nws cov yam ntxwv suav nrog:

1. Kev ua kom sov zoo heev: alumina ceramic substrate tuaj yeem ua kom sov sai sai rau lub dab dej kub, txo qhov kub ntawm lub cuab yeej thiab txhim kho kev ua haujlwm zoo.

2. Lub zog kho tshuab siab: alumina ceramic substrate muaj lub zog kho tshuab siab, tuaj yeem tiv taus kev poob siab sab nraud thiab kev co, kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv semiconductor.

3. Kev ua haujlwm rwb thaiv tsev siab: alumina ceramic substrate kuj muaj kev rwb thaiv tsev zoo, tuaj yeem ua kom muaj kev nyab xeeb ntawm cov khoom siv semiconductor hauv qhov chaw muaj hluav taws xob siab lossis siab tam sim no.

Tsis tas li ntawd, alumina ceramic substrate, zoo lichemshun 99.7% alumina wafer polished phaj, muaj kev ruaj khov tshuaj zoo thiab kev tiv thaiv corrosion, tuaj yeem ua kom ntseeg tau tias cov khoom siv semiconductor muaj kev ntseeg siab hauv cov chaw ib puag ncig hnyav.

Qhov thib peb,Daim ntawv thov hauvtus neeg nqa khoom chip

Alumina ceramic chip carrier ua ib lub semiconductor chip carrier, muaj cov yam ntxwv hauv qab no:

1. muaj zog thiab thermal conductivity siab: tuaj yeem txo qhov kub thiab txias ntawm lub nti, txhim kho kev ruaj khov thiab lub neej ntawm lub nti.

2. Kev ua haujlwm rwb thaiv tsev siab: Alumina ceramic chip carrier muaj kev rwb thaiv tsev zoo, uas tuaj yeem tiv thaiv kev cuam tshuam hluav taws xob lossis luv luv ntawm cov chip thiab lwm qhov.

3. Tus coefficient ntawm thermal expansion yog ze rau ntawm silicon (Si): nws yog qhov zoo rau kev txo cov thermal stress thiab txhim kho kev ntseeg siab ntawm lub nti.

Alumina ceramics ua lub luag haujlwm tseem ceeb hauv kev tsim khoom semiconductor nrog nws cov kev ua tau zoo heev. Txij li cov khoom siv ntim khoom mus rau cov ntaub ntawv substrate mus rau cov chip carrier thiab lwm yam txuas, alumina ceramics tau qhia txog tus nqi siv siab. Nrog rau kev txhim kho tas mus li ntawm kev lag luam semiconductor, daim ntawv thov ntawm alumina ceramics yuav ntau dua thiab dav dua, los muab kev txhawb nqa zoo rau kev nce qib ntawm kev lag luam semiconductor. Ltd. tshwj xeeb hauv kev tsim cov khoom siv alumina ceramics. Txais tos tiv tauj peb.
