Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2015179205
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a highly reliable semiconductor device which can prevent wiring delay inside a semiconductor chip and reduce power consumption by minimizing a problematic clock skew caused by wiring delay and avoiding the insertion of a number of buffer cells for clock skew control.SOLUTION: A semiconductor device comprises: a semiconductor layer 11 having a light receiving element 22 and a functional element 23; an electric wiring layer 12 formed on a principal surface of the semiconductor layer 11 and having an electrical wiring 12A connecting between the light receiving element 22 and the functional element 23; a first optical wiring layer 13a formed on a principal surface of the electric wiring layer 12; and a second optical wiring layer 13b which is connected to the first optical wiring layer 13a and extends in a perpendicular direction relative to the principal surface of the electric wiring layer 12 and is connected to the receiving element 22.
