So no microlens used in this CSP version ??
ReplyDeleteThe scale of the pictures is too small to see the microlens.
ReplyDeleteshould be, so there is an air gap between the cover glass and the BSI sensor ?
ReplyDeleteYes, it should be.
ReplyDeleteHow long will it take to over come these problem?
ReplyDeleteWhat problem are you talking about? The air gap seems to be there, microlens too. What's the problem?
ReplyDeleteInteresting that they have not yet migrated to TSVs.
ReplyDeleteHow the active wafer bonded to the carrier wafer ?
ReplyDeleteAny one can explain ?
I was told that they were bonded by Van der Waals force only; don't know the details though.
