To provide a method of manufacturing a semiconductor device which forms a non-single crystal Si thin film device and a single crystal Si thin film device and integrates a high performance system.
In the method of manufacturing a semiconductor device 20 in which a single crystal Si thin film transistor 16a and a non-single crystal Si thin film transistor 1a are formed on an insulating substrate 2, an oxide film, a gate pattern and an impurity ion implanted portion are formed on the front surface and then the surface is planarized, a single crystal Si substrate 10a having a portion 15 where hydrogen ions of predetermined concentration are implanted up to a predetermined depth is bonded onto the insulating substrate 2 by heat treatment, and an amorphous Si thin film 5 is formed after cleavage is performed at the hydrogen ion implanted portion 15 by heat treatment.
