Abstract
A cavity, such as an oven cavity, is heated by at least one monolithic integrated heat source, each fabricated by depositing a layer of resistive material on a substrate of non-conducting, or insulating, material. A pair of spaced-apart conductive elements contact opposite ends of the resistance sheet to enable a flow of current through the sheet thereby producing substantially uniform heating over the entire area covered by the resistive sheet.
