Maxay TTV, BOW, WARP, iyo TIR uga dhigan yihiin Wafers?

Marka la baarayo maraqa silikoon ee semiconductor ama substrates ka samaysan walxo kale, waxaan inta badan la kulannaa tilmaamayaasha farsamada sida: TTV, BOW, WARP, iyo suurtogalnimada TIR, STIR, LTV, iyo kuwo kale. Waa maxay xuduudaha ay kuwani u taagan yihiin?

 

TTV - Wadarta kala duwanaanshaha dhumucda
Qaansada - Qaansada
WARP - Warp
TIR - Wadarta wax-akhrinta la tilmaamay
STIR - Wadarta Akhriska la tilmaamay
LTV - Kala duwanaanshaha dhumucda deegaanka

 

1. Wadarta kala duwanaanshaha dhumucda - TTV

da81be48e8b2863e21d68a6b25f09db7Farqiga u dhexeeya dhumucda ugu badan iyo kan ugu yar ee waferka marka loo eego diyaaradda tixraaca marka wafer la isku xiro oo xiriir dhow la yeesho. Guud ahaan waxa lagu muujiyaa mikromitir (μm), oo inta badan u taagan: ≤15 μm.

 

2. Qaansada - BOOS

Kala leexashada u dhaxaysa ugu yar iyo fogaanta ugu badan ee barta dhexe ee dusha wafer ilaa diyaaradda tixraaca marka waferku ku jiro xaalad bilaash ah (aan xidhnayn). Tan waxa ku jira labada xaaladood ee concave ( qaanso xun) iyo qallafsan ( qaanso togan). Caadi ahaan waxa lagu muujiyaa mikromitir (μm), oo inta badan u taagan: ≤40 μm.

 

3. Warp - WARP

Weeca u dhexeeya masaafada ugu yar iyo fogaanta ugu badan ee dusha wafer ilaa diyaaradda tixraaca (badanaa dusha dambe ee waferka) marka waferku ku jiro xaalad bilaash ah (aan xidhnayn). Tan waxa ku jira labada xaaladood ee concave (warp xun) iyo convex (warp togan) labadaba. Guud ahaan waxa lagu muujiyaa mikromitir (μm), oo inta badan u taagan: ≤30 μm.

 

4. Wadarta wax-akhrinta la tilmaamay - TIR

Marka waferka la isku xiro oo xiriir dhow la yeesho, iyadoo la adeegsanayo diyaarad tixraac ah taasoo yareyneysa wadarta isugeynta dhammaan dhibcaha ku jira aagga tayada ama gobol cayiman oo ku yaal dusha sare ee wafer, TIR waa ka leexashada inta ugu badan iyo masaafada ugu yar ee dusha sare ee wafer ilaa diyaaradda tixraaca.

 

Waxaa lagu aasaasay khibrad qoto dheer oo ku saabsan tafaasiisha walxaha semiconductor sida TTV, BOW, WARP, iyo TIR, XKH waxay bixisaa adeegyo saxan oo wafer caadadii ah oo ku habboon heerarka warshadaha adag. Waxaan bixinaa oo taageernaa qalabyo kala duwan oo waxqabad sare leh oo ay ku jiraan sapphire, silicon carbide (SiC), wafers silicon, SOI, iyo quartz, hubinta flatness gaar ah, joogtaynta dhumucda, iyo tayada dusha sare ee codsiyada sare ee optoelectronics, qalabka korontada, iyo MEMS. Nagu kalsoonow inaan bixino xalal shay oo la isku halayn karo iyo mashiin sax ah oo buuxinaya shuruudaha naqshadaynta ee aadka u baahan.
