Abstract

PURPOSE:To make it possible to increase the density of an exothermic element by making an exothermic portion and its driving portion integral with an insulating substrate which is inexpensive and has a low thermal conductivity. CONSTITUTION:An exothermic element forming portion A of an insulating substrate 20, which has its alumina substrate coated with a glass layer 21, is formed with a film 23 of ZrB2, whereas a thin film transistor forming portion B is formed with a film 24 of amorphous Si. Then, a film 25 of Al is evaporated on the whole surface, and the films 23 to 25 are etched in a stripe shape. After that, a portion of the film 25 is selectively etched to expose the film 23 and 24 to the outside. Then, a film 26 of SiO2 is piled with different thicknesses upon the portions A and B, and the portion A is formed with a layer 27 of Ta2O5 as a wear-resisting layer. Then, the portion B is formed with an electrode for supplying a power to the film 23 acting as an exothermic resistor and with an insulating film 28 made of a polyimido resin. An aperture portion is formed and is evaporated with a layer 29 of Al for forming a gate electrode, followed by the etching process.
