Kodi TTV, BOW, WARP, ndi TIR Zimatanthauza Chiyani mu Ma Wafers?

Pofufuza ma wafer a silicon a semiconductor kapena substrates opangidwa ndi zinthu zina, nthawi zambiri timakumana ndi zizindikiro zaukadaulo monga: TTV, BOW, WARP, komanso mwina TIR, STIR, LTV, pakati pa zina. Kodi izi zikuyimira magawo ati?

TTV — Kusiyanasiyana kwa Kukhuthala Konse
Uta — Uta
WARP — Warp
TIR - Kuwerenga Konse Komwe Kwasonyezedwa
STIR — Malo Onse Owerengedwa
LTV — Kusiyanasiyana kwa Kukhuthala Kwapafupi

1. Kusintha kwa Kukhuthala Konse — TTV

Kusiyana pakati pa makulidwe apamwamba ndi ochepa a wafer poyerekeza ndi malo ofunikira pamene wafer yatsekedwa komanso yolumikizana kwambiri. Kawirikawiri imafotokozedwa mu ma micrometer (μm), nthawi zambiri imaimiridwa ngati: ≤15 μm.

2. Uta — Uta

Kupatuka pakati pa mtunda wocheperako ndi wapamwamba kwambiri kuchokera pakati pa pamwamba pa wafer kupita ku malo ofotokozera pamene wafer ili mu mkhalidwe womasuka (wosatsekedwa). Izi zikuphatikizapo mizere yonse ya concave (negative bow) ndi convex (positive bow). Nthawi zambiri imawonetsedwa mu ma micrometer (μm), nthawi zambiri imaimiridwa ngati: ≤40 μm.

3. Kupindika — KUpindika

Kupatuka pakati pa mtunda wocheperako ndi wapamwamba kwambiri kuchokera pamwamba pa wafer kupita ku malo ofotokozera (nthawi zambiri pamwamba pa wafer) pamene wafer ili mu mkhalidwe womasuka (wosaphimbidwa). Izi zikuphatikizapo milandu yonse ya concave (negative warp) ndi convex (positive warp). Kawirikawiri imafotokozedwa mu ma micrometer (μm), nthawi zambiri imaimiridwa ngati: ≤30 μm.

4. Kuwerenga Konse Komwe Kumasonyeza — TIR

Pamene wafer yaikidwa ndipo yayandikana kwambiri, pogwiritsa ntchito njira yowunikira yomwe imachepetsa kuchuluka kwa mfundo zonse mkati mwa malo abwino kapena dera linalake lapafupi pamwamba pa wafer, TIR ndi kusiyana pakati pa mtunda wapamwamba ndi wocheperako kuchokera pamwamba pa wafer kupita ku njira yowunikira iyi.

Yakhazikitsidwa ndi luso lakuya mu zinthu za semiconductor monga TTV, BOW, WARP, ndi TIR, XKH imapereka ntchito zokonza wafer zokonzedwa bwino zomwe zimagwirizana ndi miyezo yokhwima yamakampani. Timapereka ndikuthandizira mitundu yosiyanasiyana ya zipangizo zogwirira ntchito bwino kuphatikizapo safiro, silicon carbide (SiC), silicon wafers, SOI, ndi quartz, kuonetsetsa kuti pamwamba pake pali kusalala, kusinthasintha kwa makulidwe, komanso mtundu wa pamwamba pa ntchito zapamwamba mu optoelectronics, zida zamagetsi, ndi MEMS. Tikhulupirireni kuti tipereka mayankho odalirika azinthu komanso makina olondola omwe akwaniritsa zofunikira zanu zofunika kwambiri pakupanga.
