SEMICONDUCTOR DEVICE

摘要

PURPOSE:To easily perform the positioning of each device in stack structure, by forming a projection type or a recess type pattern which serves as the mark to position each circuit element constituted by stack on a substrate or an insulator layer. CONSTITUTION:The projection type or recess type patterns 2 and 2' which serve the mark to position each circuit element constituted by stack are formed on the substrate 0 or the insulator layer 3. Then, it becomes possible to easily form the second layer device 4 and a layer wiring 5 with the pattern 2' as the standard.
