Assignee: ULTRAMEMORY, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A semiconductor module comprising:
a heat spreader;
a logic chip disposed adjacent to one surface of the heat spreader, having a surface adjacent to the heat spreader and an exposed surface opposite to the surface, and including a plurality of logic chip-power supply terminals and a plurality of logic chip-signal terminals on the exposed surface;
a power supply unit juxtaposed with the logic chip in an in-plane direction of the exposed surface of the logic chip, having an exposed surface facing an identical direction with respect to the exposed surface of the logic chip, and including a plurality of power supply unit-power supply terminals on the exposed surface thereof;
a RAM unit as a RAM module having an opposing surface facing the exposed surface of the logic chip and the exposed surface of the power supply unit, and disposed across part of the plurality of logic chip-signal terminals and part of the plurality of power supply unit-power supply terminals; and
a support substrate including a power supply circuit capable of supplying electric power to the logic chip and the power supply unit, and having one main surface adjacent to a heat dissipation surface of the RAM unit opposite to the opposing surface,
wherein the support substrate is electrically connected to at least part of the logic chip-power supply terminals and another part of the power supply unit-power supply terminals by means of the power supply circuit, and has, in a portion over which the RAM unit is superimposed, a heat dissipation via that is in contact with the heat dissipation surface of the RAM unit and penetrates the support substrate in a thickness direction.
