A semiconductor package includes a first semiconductor die surrounded by a molding compound. The system further includes a motor for rotating the gimbal and an autotracker electrically coupled to the image sensor and the motor. The edge counter generates a value equal to the number of edges in the intermediate signal that have occurred since a reset signal was generated. Furthermore, since aluminum has a lower contact resistance compared with copper, dependable test results are obtained during tests of electrical characteristics. or more; anda photoinitiator which generates a base and a radical by irradiation with ultraviolet light of wavelength 200-450 nm.
