    Abstract: A structure of semiconductor device is provided. The structure includes a first bonding pattern, formed on a first substrate. A first grating pattern is disposed on the first substrate, having a plurality of first bars extending along a first direction. A second bonding pattern is formed on a second substrate. A second grating pattern, disposed on the second substrate, having a plurality of second bars extending along the first direction. The first bonding pattern is bonded to the second bonding pattern. One of the first grating pattern and the second grating pattern is stacked over and overlapping at the first direction with another one of the first grating pattern and the second grating pattern. A first gap between adjacent two of the first bars is different from a second gap between adjacent two of the second bars.

    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.
