Patent ID: 6911721

Claim:
A semiconductor device comprising: a base substrate provided with a base wiring; a first substrate that extends from a first side of the base substrate to a second side of the base substrate and includes a first wiring to be electrically connected to the base wiring on both the first and second sides of the base substrate, wherein the first substrate is provided above the base substrate; a first semiconductor element that is provided between the base substrate and the first substrate; a second substrate that extends from a third side of the base substrate to a fourth side of the base substrate and includes a second wiring to be electrically connected to the base wiring on both the third and fourth sides of the base substrate, wherein the second substrate is provided above the first substrate; and a second semiconductor element that is provided between the first substrate and the second substrate and above the first semiconductor element, wherein the first substrate has a first region where the first semiconductor element is provided below, second regions where portions of the first wiring that connect to the base wiring are located, and first bent sections between the first region and the second regions, and the second substrate has a third region where the second semiconductor element is provided below, fourth regions where portions of the second wiring that connect to the base wiring are located, and second bent sections between the third region and the fourth regions.
