Abstract:
A wafer bonding method includes providing a first wafer including a first wafer surface, forming a first metal layer on the first wafer surface, and forming a first annular retaining wall structure including a first annular retaining wall and a second annular retaining wall surrounded by the first annular retaining wall. The first metal layer is formed between the first annular retaining wall and the second annular retaining wall. The method includes providing a second wafer including a second wafer surface, forming a second metal layer on the second wafer surface, and forming a second annular retaining wall structure including a third annular retaining wall and a fourth annular retaining wall surrounded by the third annular retaining wall. The second metal layer is formed between the third annular retaining wall and the fourth annular retaining wall. The method further includes bonding the first metal layer to the second metal layer.

Claim (Index 19):
The wafer-bonded structure according to  claim 15 , wherein:\n the first annular retaining wall structure is in a region surrounded by the second annular retaining wall structure; or the second annular retaining wall structure is in a region surrounded by the first annular retaining wall structure
