    摘要: A structure for reducing partially etched materials is described. The structure includes a layout of an intersection area between two trenches. First, a large intersection area having a trapezoidal corner may be replaced with an orthogonal intersection between two trenches. The layout reduces the intersection area as well as the possibility of having partially etched materials left at the intersection area. The structure also includes an alternative way to fill the intersection area with either an un-etched small trapezoidal area or multiple un-etched square areas, so that the opening area at the intersection point is reduced and the possibility of having partially etched materials is reduced too.

    摘要: A customized seal ring for a semiconductor device is formed of multiple seal ring cells that are selected and arranged to produce a seal ring design. The cells include first cells that are coupled to ground and second cells that are not coupled to ground. The second cells that are not coupled to ground, include a higher density of metal features in an inner portion thereof, than the first seal ring cells. Dummy metal vias and other metal features that may be present in the inner portion of the second seal ring cells are absent from the inner portion of the first seal ring cells that are coupled to ground. The seal ring design may include various arrangements, including alternating and repeating sequences of the different seal ring cells.
