Wafer AlN-on-NPSS: Lakab Aluminium Nitride ah oo Waxqabad Sare leh oo ku yaal Substrate Sapphire ah oo aan la safayn oo loogu talagalay Codsiyada Heerkulka Sare, Awoodda Sare, iyo RF

Sharaxaad Gaaban:

Wafer-ka AlN-on-NPSS wuxuu isku daraa lakab aluminium nitride (AlN) oo tayo sare leh oo leh substrate sapphire ah oo aan la safayn (NPSS) si uu u bixiyo xal ku habboon codsiyada heerkulka sare, awoodda sare, iyo soo noqnoqoshada raadiyaha (RF). Isku-darka gaarka ah ee hufnaanta kulaylka ee AlN iyo sifooyinka korontada, oo ay weheliso xoogga farsamada ee substrate-ka ee aadka u fiican, ayaa ka dhigaya wafer-kan doorasho la doorbidayo codsiyada adag sida elektaroonigga korontada, aaladaha soo noqnoqda sare, iyo qaybaha indhaha. Iyada oo leh kala-baxa kulaylka oo aad u fiican, lumis hoose, iyo iswaafajinta jawiga heerkulka sare, wafer-kani wuxuu suurtogal ka dhigayaa horumarinta aaladaha jiilka xiga oo leh waxqabad sare.

Astaamaha

Lakabka AlN ee Waxqabadka Sare lehAluminium Nitride (AlN) waxaa loo yaqaanaa aashitada birta ah ee ay ku jirtoGudbinta kulaylka sare(~200 W/m·K),farqiga ballaaran, iyodanab burbur sare, taasoo ka dhigaysa agab ku habboonawood sare leh, soo noqnoqoshada sare, iyoheerkul sarecodsiyada.

Substrate Sapphire ah oo aan la dhalaalin (NPSS)Safayr aan la safayn wuxuu bixiyaa akharash-ool ah, farsamo ahaan adagsaldhig, taasoo hubinaysa saldhig deggan oo loogu talagalay koritaanka epitaxial iyada oo aan lahayn dhibka nadiifinta dusha sare. Sifooyinka farsamada ee aadka u fiican ee NPSS waxay ka dhigayaan mid waara oo loogu talagalay jawi adag.

Xasillooni Kulayl SareWafer-ka AlN-on-NPSS wuxuu u adkeysan karaa isbeddellada heerkulka ee aadka u daran, taasoo ka dhigaysa mid ku habboon in loo isticmaalo gudahaelektarooniga korontada, nidaamyada baabuurta, Nalalka LED-yada, iyocodsiyada indhahakuwaas oo u baahan waxqabad deggan xaaladaha heerkulka sare.

Dahaarka KorontadaAlN waxay leedahay sifooyin dahaadh koronto oo heer sare ah, taasoo ka dhigaysa mid ku habboon codsiyada halkaas oogo'doomin korontowaa muhiim, oo ay ku jiraanQalabka RFiyoelektarooniga microwave-ka.

Kala-baxa Kulaylka Sare: Iyada oo leh koronto-qaadis heer sare ah, lakabka AlN wuxuu hubiyaa kala-baxa kulaylka oo wax ku ool ah, taas oo lagama maarmaan u ah ilaalinta waxqabadka iyo cimri dhererka aaladaha ku shaqeeya awoodda sare iyo soo noqnoqoshada.
