Claim:
1. A semiconductor device comprising: a substrate including a first surface and a second surface opposite to the first surface; a first layer formed over the first surface, the first layer being a solder resist material; a second layer thicker than the first layer formed over a first portion of the first layer, the second layer being the same solder resist material as the first layer; a first semiconductor chip mounted over a second portion of the first layer; and a second semiconductor chip commonly mounted over the first semiconductor chip and the second layer, wherein the second semiconductor chip is rectilinear and has opposing first sides and opposing second sides, wherein the second layer has a continuous length that is longer than the length of a first side of the second semiconductor chip, and wherein the second layer extends laterally outside at least one of the first and/or second sides of the second semiconductor chip.
