Abstract
A stacked semiconductor device and an associated manufacturing method are disclosed. A first semiconductor unit having a first surface, which is defined as being not a polar plane, is provided. At least one pit is formed on the first surface, and the pit has a second surface that lies at an angle relative to the first surface. A polarization enhanced tunnel junction is formed on the second surface, and a second semiconductor unit is formed above the tunnel junction.
