Abstract
A hybrid (composite) integrated circuit element comprises a substrate, a thin film type integrated circuit formed on a substrate through a thin film process, and a lamination type passive circuit element such as a capacitor, inductor, resitance and a combination thereof formed on the integrated circuit. During the firing of passive circuit element in a hydrogen atmosphere, the semiconductor layer which constitutes the integrated circuit is also heat annealed. Various substrates can be used as the substrate, for example, quartz, ceramic and a cheap semiconductor substrate which has not been treated with a mirror-grinding by the use of a glass layer.
