Menene ainihin wafer mai siriri sosai?

Matsakaicin kauri (misali wafers 8″/12″)

• Wafer na yau da kullun:600–775 μm

• Wafer mai laushi:150–200 μm

• Wafer mai siriri sosai:ƙasa da 100 μm

• Wafer mai siriri sosai:50 μm, 30 μm, ko ma 10–20 μm

Me yasa wafers ke zama siriri?

• Rage kauri na fakitin gaba ɗaya, rage tsawon TSV, da rage jinkirin RC

• Rage juriya da kuma inganta zubar da zafi

• Cika buƙatun samfurin ƙarshe don abubuwan da suka fi siriri sosai

Babban haɗarin wafers masu siriri sosai

1. Ƙarfin injina yana raguwa sosai

2. Yaƙi mai tsanani

3. Wuya wajen sarrafawa da jigilar kaya

4. Tsarin gefen gaba yana da matuƙar rauni; wafers suna da saurin fashewa/karyewa
