However, in such a conventional intaglio printing apparatus,
The transferred material (8) is pressed against the intaglio plate (4) by the impression cylinder (7) to bend the transferred material (8) into the recess (5) of the intaglio plate (4), and the ink (3B) in the recess (5) is pressed. However, there is a disadvantage that it cannot be transferred to a material to which a large pressure cannot be applied because the transfer is performed by bringing the material into contact with the material to be transferred (8). For example, if the conventional intaglio printing apparatus is used to print and form a surface protective film of a polyimide resin on a semiconductor integrated circuit element, it is necessary to press the semiconductor integrated circuit element against the intaglio plate (4) with a large pressure.
The semiconductor integrated circuit element may be damaged.
In order to avoid this, when this semiconductor integrated circuit element is pressed against the intaglio plate (4) with a weak pressure, the surface of the semiconductor integrated circuit device is highly uneven, so that the intaglio plate (4) is evenly distributed over the surface of the semiconductor integrated circuit device. However, there is a disadvantage that a good polyimide layer cannot be formed.

When the polyimide layer (14D) is formed by using intaglio printing in this way, a protective film layer is formed on the entire surface of the semiconductor wafer (13) by, for example, spin coating, as is conventionally done. After formation, this protective film material layer is heat-treated to form a polyimide layer, and then a resist is deposited on the polyimide layer, and then this resist is formed into a predetermined pattern, and this resist is masked. As a complicated process step of etching the polyimide layer to a predetermined pattern is not required, a simple step, that is, a polyimide layer having a predetermined pattern in one printing step and the subsequent heat treatment step (14D ) Can be formed.
