Patent ID: 11894403
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 13:
14. A semiconductor package comprising:
a package substrate;
a semiconductor chip mounted on the package substrate;
a transparent substrate disposed on the semiconductor chip;
an attachment dam between the semiconductor chip and the transparent substrate, the attachment dam extending along an edge of the semiconductor chip to define a gap between the semiconductor chip and the transparent substrate;
a first molding layer on the package substrate, the first molding layer surrounding a side surface of the semiconductor chip; and
a second molding layer on the package substrate, the second molding layer filling a space between the semiconductor chip and the first molding layer,
wherein a coefficient of thermal expansion (CTE) of the second molding layer is smaller than that of the first molding layer, and
wherein the first molding layer includes a first epoxy resin composition having a first thixotropic index, the second molding layer includes a second epoxy resin composition having a second thixotropic index, and the first thixotropic index is greater than the second thixotropic index.
