Abstract: A 3D semiconductor structure includes a buffer layer, a n-type high electron mobility transistor (HEMT) disposed on a first surface of the buffer layer, and a p-type high hole mobility transistor (HHMT) disposed on a second surface of the buffer layer opposite to the first surface.

Abstract: A die seal ring is provided. The die seal ring includes a substrate and a first layer extruding from the substrate. The first layer has a first fin ring structure and a layout of the first fin ring structure has a stamp-like shape. In addition, a method for forming a die seal ring is provided. A substrate having an active region is provided. A patterned sacrificial layer is formed on the substrate. A spacer is formed on the sidewall of the patterned sacrificial layer. The patterned sacrificial layer is removed. The substrate is patterned by using the spacer as a mask, thereby simultaneously forming at least a fin structure of a Fin-FET and a first layer of the die seal ring.
