Product objectives

This is a full reverse costing and technology report on the IMX888 Exmor T CIS with 2-layer transistor pixel.  It includes complete technical and physical analysis of the CIS with images from optical and scanning electron microscopy (SEM) and chemical analysis by energy-dispersive X-ray (EDX) spectroscopy.  We then use this information combined with supply chain analysis to determine the manufacturing steps and calculate the cost breakdown.  Finally, we estimate the final selling price of the CIS.  Physical and cost comparison is made between the Exmor  T and Exmor RS technologies.
