Abstract
A protective layer for use on a sensor during a manufacturing process avoids damage to the sensor and keeps the sensor surface clean during lens fabrication. The protective layer includes a non-cross-linked, water-soluble polymer layer and an anhydrous, cross-linkable, methacrylate-based formulation layer, temporarily applied to a surface of the sensor. The protective layer may be used to protect the sensor during a manufacturing process by applying the non-cross-linked, water-soluble polymer layer and the anhydrous, cross-linkable, methacrylate-based formulation layer consecutively onto the surface of the sensor to form the protective layer; affixing the sensor to a substrate; fabricating a device that includes the substrate; and subsequently removing the protective layer from the surface of the sensor.
