The invention discloses a control method of a hot rolling width of a wedge-shaped slab. The control method is used in hot rolling of rough mills and used for controlling the hot rolling width of the wedge-shaped slab. The control method includes the following steps that firstly, whether an incoming slab is a wedge-shaped slab or not is judged according to the width difference of the head and the tail of the incoming slab which is to enter a rough mill to undergo rough rolling processing; secondly, when the incoming slab is determined to be the wedge-shaped slab, the type of the wedge-shaped slab is determined according to the width difference of the head and the tail; thirdly, width control is performed on wedge-shaped slabs in multiple racks in the rough mill which the wedge-shaped slab enters according to the wedge-shaped slab type which is determined in the second step. The control method of the hot rolling width of the wedge-shaped slab automatically controls widths of the wedge-shaped slabs which have the abnormal widths in the full length direction in the rough rolling process of a hot rolling mill.

In a method of manufacturing a semiconductor device suitable for an image sensor, a bonding region is formed on the lower insulating layer after forming a lower insulating layer on a substrate. Then, an upper insulating layer is formed on the substrate to cover the bonding area. The upper insulating layer is selectively removed to expose a top portion of the bonding region. Subsequently, a protective layer is formed on the substrate. After forming several color filter elements on the protection layer, a planar layer is formed to cover the color filter elements. Finally, several microlenses are formed on the plane layer.
