Abstract:
1. A method of manufacturing a semiconductor device that includes a first semiconductor chip and a second semiconductor chip formed above the first semiconductor chip, the method comprising: preparing a semiconductor substrate that includes the first semiconductor chip having an integrated circuit, the first semiconductor chip being formed in a first main surface of the semiconductor substrate; removing a part of a first dielectric layer of a photoresist type as a single layer formed on the first main surface of the semiconductor substrate by lithography, thereby forming a recess in the first dielectric layer so that a bottom surface of the recess is formed by the first dielectric layer and does not reach the first main surface of the semiconductor substrate; mounting the second semiconductor chip including a first electrode pad on the bottom surface of the recess, the bottom surface of the recess having adhesive properties; forming a second dielectric layer so as to cover the first dielectric layer and the second semiconductor chip; forming a first aperture penetrating the second dielectric layer so that the first electrode pad is exposed to the first aperture; and forming a first wiring extending from the first electrode pad to an upper surface of the second dielectric layer, the first wiring being electrically connected to the first electrode pad.
