Abstract
A composite substrate having silicon substrate with excellent crystallinity and a method of manufacturing the composite substrate and an electronic component using the composite substrate are provided. A composite substrate () is configured to bond a support substrate () having electrical insulating property, and a silicon substrate () which is overlaid on the support substrate (). The semiconductor substrate () of the composite substrate () includes a plurality of first regions () in which a device function unit functioning as a semiconductor device is formed, and a second region () located between these first regions (). In the semiconductor substrate () of the composite substrate (), an amorphous form () containing silicon and a metal is present in the second region ().
