摘要:
Provided is a wafer level packaging. The packaging includes a first semiconductor wafer having a transistor device and a first bonding layer that includes a first material. The packaging includes a second semiconductor wafer having a second bonding layer that includes a second material different from the first material, one of the first and second materials being aluminum-based, and the other thereof being titanium-based. Wherein a portion of the second wafer is diffusively bonded to the first wafer through the first and second bonding layers.
