There are provided a semiconductor device capable of accurately determining whether a semiconductor chip is bonded to a solid-state device such as the other semiconductor chip parallelly with each other, a semiconductor chip used for the semiconductor device, and a method of manufacturing the semiconductor chip. The semiconductor chip includes a functional bump projected with a first projection amount from the surface of the semiconductor chip and electrically connecting the semiconductor chip to the solid-state device, and a connection confirmation bump projected with a second projection amount, which is smaller than the first projection amount, from the surface of the semiconductor chip and used for confirming the state of the electrical connection by the functional bump.
