Ithetha ukuthini i-TTV, i-BOW, i-WARP, kunye ne-TIR kwii-Wafers?

Xa sihlola ii-wafers ze-silicon ze-semiconductor okanye ii-substrates ezenziwe ngezinye izinto, sihlala sidibana neempawu zobugcisa ezifana nezi: TTV, BOW, WARP, kwaye mhlawumbi TIR, STIR, LTV, phakathi kwezinye. Zeziphi iiparameter ezimele ezi?

I-TTV — Utshintsho loBukhulu obupheleleyo
I-BOW — I-Bow
I-WARP — I-Warp
I-TIR — Ukufundwa Okupheleleyo Okubonisiweyo
I-STIR — Indawo iyonke ebonisiweyo yokufunda
I-LTV — Utshintsho loBukhulu bendawo

1. Utshintsho loBukhulu obupheleleyo — TTV

Umahluko phakathi kobukhulu obukhulu nobuncinci be-wafer xa kuthelekiswa ne-reference plane xa i-wafer ibotshelelwe kwaye isondelelene. Idla ngokubonakaliswa kwii-micrometer (μm), ezidla ngokuboniswa ngolu hlobo: ≤15 μm.

2. Isaphetha — Isaphetha

Ukuphambuka phakathi komgama omncinci nowona mkhulu ukusuka kwindawo ephakathi yomphezulu we-wafer ukuya kwindawo yokubhekisa xa i-wafer ikwimeko ekhululekileyo (engafakwanga isibane). Oku kuquka zombini iimeko ze-concave (negative bow) kunye ne-convex (positive bow). Ihlala ibonakaliswa kwii-micrometers (μm), ezidla ngokumelwa ngolu hlobo: ≤40 μm.

3. I-Warp — I-WARP

Ukuphambuka phakathi komgama omncinci nowona mkhulu ukusuka kumphezulu we-wafer ukuya kwindawo yokubhekisa (ngesiqhelo umphezulu ongasemva we-wafer) xa i-wafer ikwimeko ekhululekileyo (engafakwanga isibane). Oku kuquka zombini iimeko ze-concave (negative warp) kunye ne-convex (positive warp). Ibonakaliswa ngokubanzi kwii-micrometers (μm), ezidla ngokumelwa ngolu hlobo: ≤30 μm.

4. Ukufundwa Okupheleleyo Okubonisiweyo — TIR

Xa i-wafer ibotshelelwe kwaye isondelelene, kusetyenziswa i-reference plane enciphisa isixa se-intercepts sawo onke amanqaku kwindawo yomgangatho okanye ummandla othile wendawo kumphezulu we-wafer, i-TIR kukuphambuka phakathi komgama ophezulu kunye nomncinci ukusuka kumphezulu we-wafer ukuya kule plane yereferensi.

Isekelwe kubuchule obunzulu kwiinkcukacha zezinto ze-semiconductor ezifana ne-TTV, i-BOW, i-WARP, kunye ne-TIR, i-XKH ibonelela ngeenkonzo zokucubungula i-wafer ngokwezifiso ezenzelwe imigangatho eqinileyo yoshishino. Sibonelela kwaye sixhasa uluhlu olubanzi lwezixhobo ezisebenza kakuhle kubandakanya i-sapphire, i-silicon carbide (SiC), ii-silicon wafers, i-SOI, kunye ne-quartz, siqinisekisa ukuba zithe tyaba kakhulu, ukuqina okuqinileyo, kunye nomgangatho womphezulu kwizicelo eziphambili kwi-optoelectronics, izixhobo zamandla, kunye ne-MEMS. Sithembe ukuba siza kubonelela ngezisombululo zezinto ezinokuthenjwa kunye nomatshini wokulungisa ngokuchanekileyo ohlangabezana neemfuno zakho zoyilo ezifuna kakhulu.
