SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE HAVING POWER GENERATION FUNCTION
Document Type and Number:
WIPO Patent Application WO/2020/184235
Kind Code:
A1
Abstract:
[Problem] To provide a semiconductor integrated circuit device having a power generation function, which makes it possible to suppress an increase in size of a circuit board. [Solution] A power generation function-equipped semiconductor integrated circuit device 200 has a semiconductor integrated circuit device and a thermoelectric element 1. The semiconductor integrated circuit device includes a package 210 in which a semiconductor integrated circuit chip 230 is housed. The semiconductor integrated circuit chip 230 has a lower surface opposing a circuit board and an upper surface opposing a mounting surface. The thermoelectric element 1 includes: a casing part having a housing section; a first electrode portion disposed in the housing section; a second electrode portion that is disposed in the housing section and opposes the first electrode portion so as to be separated in a first direction from the first electrode portion and that has a work function different from that of the first electrode portion; and an intermediate section that includes nanoparticles and is disposed between the first electrode portion and the second electrode portion in the housing section and that has a work function between the work function of the first electrode portion and the work function of the second electrode portion. The casing part is disposed in the circuit board 260.
