Patent ID: 11955345
Assignee: MICRON TECHNOLOGY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor die assembly, comprising:
an interface die;
a semiconductor die attached to a surface of the interface die, the semiconductor die having a first height from the surface; and
an encapsulant over the surface and surrounding the semiconductor die, the encapsulant including an outer sidewall having:
a lower segment in a first plane extending from the surface to a second height less than the first height, the lower segment having a first surface texture; and
an upper segment in a second plane different from and parallel to the first plane and extending from the second height to the first height, the upper segment having a second surface texture different from the first surface texture, wherein the second plane is spaced further from a center of the semiconductor die assembly than the first plane.
