Abstract
A substrate fixing device includes a baseplate, an electrostatic chuck, and an insulating layer interposed between the baseplate and the electrostatic chuck. The insulating layer includes a heating element formed of a first material and a wiring line connected in series to the heating element. The wiring line includes a first conductive layer formed of the first material and a second conductive layer joined onto the first conductive layer. The second conductive layer is formed of a second material having a resistivity lower than the resistivity of the first material.
