Patent ID: 7682936

Claim:
A method for reducing a thickness of a semiconductor component on a substrate, the method comprising the steps of: preparing a base plate; preparing a substrate on which a semiconductor component is mounted; preparing a fixation device including a bottom portion and leg portions, in which a distance between a surface of the bottom portion and an end surface of each of the leg portions has a predetermined length; temporarily tacking the substrate to the fixation device using a first fixing material that is made of a light-curable material so that a surface of the semiconductor component may join the surface of the bottom portion of the fixation device; placing the fixation device to which the substrate is temporarily tacked onto a surface of the base plate, and further temporarily tacking a surface of the substrate on the side where the semiconductor component is not mounted to the surface of the base plate using a second fixing material that is made of a light-curable material; releasing the temporary tacking between the fixation device and the semiconductor component, and removing the fixation device from the surface of the base plate; machining the exposed surface of the semiconductor component on the base plate; and releasing the temporary tacking between the substrate after being machined and the surface of the base plate, and separating the substrate and the base plate from each other.
