This invention provides a mounting method which, when an object such as an element, particularly a minute object, is mounted on a board, can realize the mounting easily and reliably with high positional accuracy. In the mounting method, an element holding layer (12) formed of a material which can regulate viscosity is formed on a board (11). In the element holding layer (12), the viscosity of a first portion (12a) including a mounting region of the element is regulated so that the element is movable by itself, and, in addition, the viscosity of a second portion (12b), which is the outside of the first portion (12a), is regulated so that the element is not movable by itself. After mounting one element (13) on the first portion (12a), the viscosity of the first portion (12a) is regulated so that an element (13) is not movable by itself.

A semiconductor device and manufacturing method thereof are provided to prevent the paste from being flowed out the rear side of sealer from the chip loading part by forming the step part lower than the chip mounting face in the peripheral part. The Ag paste(6) is arranged on the supporting surface of a chip(1c) of the tap(1b). The semiconductor chip is mounted on the tap through the Ag paste. The pad(2a) of the semiconductor chip and the lead(1a) of the tap are electrically connected with a plurality of wires(4). The semiconductor chip and the plurality of wires are sealed by the sealer(3). The step part(1e) is formed in the peripheral part of the supporting surface of a chip of the tap. The step part is lower than that of the supporting surface of a chip. Therefore, the Ag paste stays within the step part.
