A method is provided and includes the following steps. A first wafer is coupled to a first support of a bonding tool and a second wafer is coupled to a second support of the bonding tool. The second wafer is bonded to the first wafer with the first wafer coupled to the first support. Whether a bubble is between the bonded first and second wafers in the bonding tool is detected.

Method for bonding wafers and bonding tool

A system, a control method and an apparatus for chemical mechanical polishing (CMP) are introduced in the present application. The CMP apparatus may include a polishing pad, a first sensor, a polishing head and a condition. The polishing pad has a plurality of groves arranged randomly or in a specific pattern. The first sensor is configured to measure the pad profile of the polishing pad, where the pad profile includes the depth of each of the grooves on the polishing pad. The polishing head and the conditioner are operated according to at least one polishing condition, and the at least one polishing condition is tuned according to the pad profile.

System, control method and apparatus for chemical mechanical polishing

A semiconductor device and a method for fabricating the semiconductor device are provided. In the method for fabricating the semiconductor device, at first, a dielectric layer is provided. Then, trenches are formed in the dielectric layer. Thereafter, the trenches are filled with spacer material to form a spacer structure in the dielectric layer for defining pixel regions. Then, lens structures are formed on the pixel regions. Each of the lens structures includes a first curved lens layer, a second curved lens layer and a curved color filter layer. The curved color filter layer is disposed on the second curved lens layer or between the first curved lens layer and the second curved lens layer.
