Zusammenfassung:	The present disclosure relates to semiconductor structures and, more particularly, to seal ring structures with channels and methods of manufacture. The structure includes: a first wafer having a channel formed within a passivation layer; a second wafer having a protuberance which is insertable into the channel and which is bonded to the first wafer with eutectic bonding materials; and a plurality of stoppers or tabs extending within the channel and which provides a gap that has a dimension smaller than a gap formed in other portions of the channel.
