BSI's price is much higher than FSI.
In fact, not only Sony and TSMC, but also Micron, Samsung, Dongbu, ST have the technologies.
Especially ST and Micron have lots of patents related to BSI.
Using BSI will face serious optical cross talk issues. Sony uses its unigue colot filter to solve the problem. However, you cannot see significant difference between its BSI and FSI products.
According to some unconfimed news, SETi also tried the BSI. However, the C/P ratio cannot convince customers to use that. |
