A method of separating a semiconductor substrate having an implementation member attached thereon includes a dividing process for at least the implementation member on the semiconductor substrate along a separation line, a placing process for film member on a same side as the implementation member, a forming process area by irradiating a laser beam from at least one of a first side of the semiconductor substrate having the implementation member and a second side that is an opposite side of the first side of the semiconductor substrate along the separation line with a focusing point of the laser beam aligned with a substance in the semiconductor substrate and severing/removing at least one semiconductor chip at the separation line from the semiconductor substrate.
