Sarrafa da Halayen Ceramics Masu Lanƙwasa na Silicon Carbide

Ⅰ. Gabatarwa

Tukwane masu ramuka na Silicon Carbide (Porous SiC)kayan yumbu ne na zamani waɗanda suka haɗu da kyawawan halaye na silicon carbide tare da tsarin ramuka masu kyau da aka ƙera da kyau. Ba kamar yumbu mai yawa na SiC ba, SiC mai ramuka yana gabatar da ramuka masu haɗin kai waɗanda ke ba da ƙarin ayyuka, gami da ikon shiga cikin ruwa mai sarrafawa, ƙira mai sauƙi, rufin zafi, da haɓaka ƙarfin jigilar ruwa.

Tare da kyakkyawan kwanciyar hankali na zafi, juriya ga sinadarai, da kuma amincin injina, yumbu mai ramuka na SiC sun zama masu mahimmanci a masana'antu masu zafi sosai, musamman masana'antar semiconductor, inda yanayin aiki ke buƙatar tsafta mai yawa, juriya ga tsatsa, da kwanciyar hankali na aiki na dogon lokaci.

Ⅱ. Sifofin Kayan Gilashin Silikon Carbide Mai Porous

1. Kwanciyar Hankali Mai Yawan Zafi

An san silicon carbide saboda kyakkyawan aikinsa a ƙarƙashin yanayin zafi mai tsanani saboda ƙarfin haɗin Si-C covalent. Porous SiC yana kiyaye daidaiton tsari a cikin yanayin zafi mai yawa, wanda hakan ya sa ya dace da sarrafa zafin semiconductor, tsarin epitaxy, da sassan tanderu.

Ƙananan faɗuwar zafi da kuma kyakkyawan juriya ga girgizar zafi suna taimakawa wajen rage nakasa da inganta kwanciyar hankali na tsari.

2. Mafi kyawun juriya ga sinadarai da jini

Kera na'urorin Semiconductor ya ƙunshi iskar gas mai ƙarfi da muhallin plasma, gami da iskar gas mai tushen chlorine, plasma mai fluorine, da kuma yanayin zafi mai zafi.

Ana bayar da tukwane masu ramuka na SiC:

• Kyakkyawan juriya ga iskar shaka
• Babban kwanciyar hankali na sinadarai
• Ƙarfin juriya ga zaizayar jini
• Ƙananan halaye na gurɓatawa

Waɗannan fa'idodi suna taimakawa rage samar da barbashi da kuma tsawaita tsawon rayuwar kayan aikin semiconductor.

3. Porosity mai sarrafawa da kuma ikon shigar iskar gas

Babban fa'idar SiC mai ramuka shine tsarin ramukan da za a iya daidaita shi. Ta hanyar sarrafa girman ramukan, rarrabawa, da haɗin kai, masana'antun za su iya inganta daidaito tsakanin ƙarfin injina da kuma ikon shiga.

Wannan fasalin na musamman yana bawa SiC mai ramuka damar aiki kamar haka:

• Kayan watsa iskar gas
• Tsarin tacewa
• Abubuwan sarrafa zafi

Ⅲ. Fasahohin Sarrafa Yumburan Silikon Carbide Masu Porous

Aikin tukwanen SiC mai ramuka ya dogara ne da hanyoyin masana'antu da ƙirar ƙananan tsari.

Ragewar Carbothermal

Wannan tsari na gargajiya yana samar da SiC mai ramuka ta hanyar halayen zafi mai yawa tsakanin kayan da ke ɗauke da silicon da tushen carbon. Yana ba da damar samar da tsarin SiC mai tsabta tare da kyakkyawan kwanciyar hankali na zafi.

Sintering na Lokaci na Ruwa

Sinta mai tsari-ruwa yana amfani da ƙarin abubuwa don inganta haɗin ƙwayoyin cuta da yawansu. Ta hanyar daidaita yanayin zafin sinta da sinadaran ƙari, masana'antun za su iya samun ingantaccen ƙarfin injina da rarraba ramuka.

Shigar Tururin Sinadarai (CVI)

CVI yana shigar da abubuwan da ke haifar da iskar gas a cikin tsarin ramuka, inda SiC ke taruwa a saman ciki. Wannan hanyar tana inganta ƙarfin tsari, tsarki, da juriya mai yawa.

Hanyoyin Kumfa da Samfura

Fasaha mai amfani da kumfa da samfuri tana ƙirƙirar tsarin ramuka masu tsari ta hanyar sarrafa abubuwan da ke samar da ramuka ko samfuran hadaya. Waɗannan hanyoyin suna ba da kyakkyawan yanayin shiga da kuma tsarin ramuka na musamman.

Ⅳ. Aikace-aikace a Masana'antar Semiconductor

Saboda haɗinsa na musamman na yanayin zafi, sinadarai, da tsarin gini, ana ƙara amfani da yumbun SiC mai ramuka a cikin hanyoyin semiconductor.

Kayan Rarraba Gas

A cikin tsarin CVD, PECVD, da ALD, SiC mai ramuka na iya zama masu watsa iskar gas da faranti na rarrabawa don cimma daidaiton kwararar iskar gas da inganta daidaiton ajiyar fim.

Kayan Aikin Sarrafa Plasma

A cikin tsarin cire ƙwayoyin cuta da tsaftacewa na plasma, abubuwan SiC masu ramuka suna ba da juriya mai kyau ga muhallin plasma mai lalata, suna rage gurɓatar ƙwayoyin cuta da inganta amincin kayan aiki.

Tsarin SiC da GaN Epitaxy

Ga masana'antar semiconductor na ƙarni na uku, SiC mai ramuka yana ba da gudummawa ga ingantaccen sarrafa zafi da kwanciyar hankali na tsari a cikin yanayin girma na epitaxial mai zafi mai zafi.

Abubuwan Gudanar da Wafer

Injin tsabtace injin tsabtace SiC mai porouskumatallafin wafersamar da daidaito mai kyau, ƙarancin gurɓatawa, da kuma juriya ga sinadarai masu kyau don duba wafer, lithography, da sarrafa zafi.

Ⅴ. Kammalawa

Tukwane masu lanƙwasa na Silicon Carbidewakiltar juyin halitta naKayan SiCdaga yumbu na gargajiya zuwa ga sassan semiconductor masu aiki. Ta hanyar fasahar sarrafawa ta zamani da kuma sarrafa tsarin ramuka daidai, SiC mai ramuka yana cimma daidaito mai kyau tsakanin ƙarfi, ƙarfin da ke shiga, aikin zafi, da kuma daidaiton sinadarai.

Yayin da masana'antar semiconductor ke ci gaba da ci gaba zuwa yanayin zafi mai yawa da kuma tsauraran matakan shawo kan gurɓatawa, yumbun SiC mai ramuka zai taka muhimmiyar rawa a cikinTsarin CVD, kayan aikin sarrafa plasma, sarrafa wafer, da fasahar ƙera semiconductor na gaba.
