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 1):
A wafer bonding method, comprising:\n providing a first wafer including a first wafer surface; forming a first metal layer on a portion of the first wafer surface; forming a first annular retaining wall structure including a first annular retaining wall and a second annular retaining wall on the first wafer surface, wherein the first annular retaining wall and the second annular retaining wall are separated from each other, the second annular retaining wall is formed on the first wafer surface surrounded by the first annular retaining wall, and the first metal layer is formed on the first wafer surface between the first annular retaining wall and the second annular retaining wall; providing a second wafer including a second wafer surface; forming a second metal layer on a portion of the second wafer surface; forming a second annular retaining wall structure including a third annular retaining wall and a fourth annular retaining wall on the second wafer surface, wherein the third annular retaining wall and the fourth annular retaining wall are separated from each other, the fourth annular retaining wall is formed on the second wafer surface surrounded by the third annular retaining wall, and the second metal layer is formed on the second wafer surface between the third annular retaining wall and the fourth annular retaining wall; and bonding the first metal layer and the second metal layer together.
