Assignee: LMDJ MANAGEMENT LLC
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. The semiconductor structure of claim 5, wherein:
the first metallization layer includes:
a first CTE (coefficient of thermal expansion) mismatch induced stress compensation layer at the bottom of the semiconductor device and in contact with the first Ag—In solid solution layer; and
a first diffusion barrier layer above the first CTE mismatch induced stress compensation layer and fully separate from the first Ag—In solid solution layer by the first CTE mismatch induced stress compensation layer; and

the second first metallization layer includes:
a second CTE mismatch induced stress compensation layer at the top of the heat-spreading mount and in contact with the second Ag—In solid solution layer; and
a second diffusion barrier layer below the first CTE mismatch induced stress compensation layer and fully separate from the second Ag—In solid solution layer by the second CTE mismatch induced stress compensation layer.
