A multi-layer and method of making the same are provided. The multi-layer, such as a sensor, can include a high strength glass overlay and a lamination layer on a substrate layer. The overlay can be less than 250 micrometers thick and have at least one tempered surface incorporating a surface compression layer of at least 5 micrometers deep and a surface compressive stress of at least 200 MPa. The overlay can exhibit a puncture factor of at least 3000 N/&#x3bc;mat B10 (10percentile of the probability distribution of failure) in a multi-layer structure, an apparent thickness of less than 0.014 mm, and a pencil hardness greater than 6H. The method can include ion-exchange tempering at least one major surface of a glass sheet, light etching the major surface to remove flaws and laminating the glass sheet on the tempered and lightly etched major surface to a substrate layer.
