Abstract
A semiconductor device substrate has fine terminals with a small pitch and is able to be easily produced at a low cost without using a special process. A mounting terminal has a pyramidal shape and extending between a front surface and a back surface of a silicon substrate. An end of the mounting terminal protrudes from the back surface of the silicon substrate. A wiring layer is formed on the front surface of the silicon substrate. The wiring layer includes a conductive layer that is electrically connected to the mounting terminal.
