PURPOSE:To provide a manufacture capable of forming a preform with a desired thickness (that is, desired volume) and a precise shape. CONSTITUTION:A mask 12 in which an opening with desired shape and size is formed is placed on a film 11 serving as a base. In this condition, a thin film layer 13 of a preform material with a desired thickness is formed on the film 11 and then the thin film layer 13 is removed from the film 11. By this, a manufacture of forming a preform for die bonding is provided so as to form the preform with the desired shape, size and thickness. |
