A semiconductor package, comprising:
- at least one semiconductor device on a first substrate;
- a first thermosetting resin layer on a top of the at least one semiconductor device;
- a second thermosetting resin layer between a bottom of the at least one semiconductor device and the first substrate, at least one of the first thermosetting resin layer and the second thermosetting resin layer including an irreversible thermochromic pigment;
- and
- a metal plate on the first thermosetting resin layer.
2 more elements
A thermal interface material (TIM) paste, comprising:
- a matrix polymer, the matrix polymer including a thermosetting resin;
- an irreversible thermochromic pigment uniformly dispersed in the matrix polymer;
- a cross-linking agent;
- and
- a cross-linking regulator,
- wherein a color change temperature of the irreversible thermochromic pigment is about 60° C. to about 400° C., and
- wherein a content of the irreversible thermochromic pigment is about 0.1 wt % to about 5 wt %, based on a total weight of the TIM paste.
