    Abstract: In a method of manufacturing a semiconductor device first conductive layers are formed over a substrate. A first photoresist layer is formed over the first conductive layers. The first conductive layers are etched by using the first photoresist layer as an etching mask, to form an island pattern of the first conductive layers separated from a bus bar pattern of the first conductive layers by a ring shape groove. A connection pattern is formed to connect the island pattern and the bus bar pattern. A second photoresist layer is formed over the first conductive layers and the connection pattern. The second photoresist layer includes an opening over the island pattern. Second conductive layers are formed on the island pattern in the opening. The second photoresist layer is removed, and the connection pattern is removed, thereby forming a bump structure.
