METHODS OF FORMING CURVED IMAGE SENSORS

摘要

A method for forming curved image sensors may include applying positive pressure to the face of an image sensor, forcing the image sensor to adhere the curved surface of a substrate. The pressure may be applied to the face of the image sensor in a variety of ways, including using pneumatic pressure, hydraulic pressure, or pressure from an elastic or inelastic solid. Processing may occur on either a single image sensor die or an image sensor wafer. When an image sensor wafer is processed, a substrate may be used that has a number of cavities defined by respective curved surfaces with each cavity corresponding to a respective image sensor. When pressure is applied to the image sensor, the image sensor may deform until the curvature of the image sensor matches the curvature of the curved surface of the underlying substrate.
