Kuleyliyaha Wafer Ceramic AlN Alumina Element

Kuleyliyaha Wafer Ceramic AlN Alumina Element
In wax soo saarka semiconductor, wafers waxay u baahan yihiin in lagu farsameeyo habab kala duwan, sida dhigista filimka khafiifka ah, etching, iwm. In links kuwan, wafers waxay u baahan yihiin in la kululeeyo si heerkul gaar ah, oo waxaa jira shuruudo adag heerkulka, sababtoo ah labbiska heerkulka ayaa saameyn aad u muhiim ah oo ku saabsan wax soo saarka alaabta, iyo qaybaha kululaynta waa lagama maarmaan.

Kuleyliyaha dhoobadasi toos ah ayaa loogu dabaqayaa qolka habsocodka waxayna si toos ah ula xiriiraan waferka. Ma aha oo kaliya inay qaadaan maraqa, laakiin sidoo kale waxay hubiyaan in maraqa uu helo heerkul deggan oo isku mid ah. Waxay yihiin qaybaha muhiimka ah ee semiconductor qalabka dhigista filimka khafiifka ah!

Kuleyliyaha dhoobada waxaa ku jira saldhig dhoobo ah oo taageera waferka iyo jirka taageerada cylindrical ee dhinaca dambe ee taageeraya. Marka lagu daro walxaha iska caabinta (lakabka kulaylka) ee kuleylka, waxaa sidoo kale jira electrodes-ka soo noqnoqda raadiyaha (lakabka RF) gudaha ama dusha sare ee saldhigga dhoobada. Si loo gaaro kuleyl degdeg ah iyo qaboojin, dhumucda saldhigga dhoobada waa in ay ahaataa mid khafiif ah, laakiin aad u dhuuban ayaa sidoo kale yareyn doonta adkaanta.

Taageerada kuleyliyaha dhoobada guud ahaan waxaa laga sameeyaa walxo dhoobo ah oo leh koronto fidinta kuleylka oo la mid ah kan saldhigga. Kuleyliyuhu wuxuu qaataa qaab-dhismeed gaar ah oo ah usheeda hoose ee wadajirka ah si uu uga ilaaliyo xirmooyinka iyo fiilooyinka saameynta balaasmaha iyo gaaska kiimikada wasakhaysan. Taageeradu waxay ku qalabaysan tahay gaaska wareejinta kulaylka iyo tubooyinka ka baxa si loo hubiyo heerkulka isku midka ah ee kuleyliyaha. Saldhigga iyo taageeradu waxay kiimiko ahaan ugu xidhan yihiin lakab xidhidh.

Kuleyliyaha dhoobada waxaa laga samayn karaa dhoobada sida aluminium nitride (AlN), silicon nitride (Si3N4), iyo alumina (Al2O3). Waxaa ka mid ah, AlN waa doorashada ugu fiican ee kuleyliyaha dhoobada. Marka la barbardhigo walxaha kale, dhoobada VET Energy's AlN waxay leedahay sifooyinka soo socda:
(1) Dhaqdhaqaaq kuleyl oo wanaagsan;
(2) Isku xidhka ballaadhinta kulaylka ku habboon iyo agabka silikoon ee semiconductor;
(3) Qalabka farsamada ee wanaagsan, caabbinta xirashada aadka u fiican, iyo sifooyin farsamo oo dhamaystiran ayaa ka fiican beryllium oxide oo u dhiganta aluminium oxide;
(4) Sifooyin koronto oo dhameystiran oo heer sare ah, dahaar koronto oo heer sare ah iyo lumis koronto yar;
(5) Aan sun ahayn oo deegaan ahaan u wanaagsan.
