Title: Fixing method for leadframe and radiator
Inventor: TAKAHATA KAZUMI
IPC: H01L23/50
Filed: 1992-09-14
Abstract: PURPOSE:To reduce the quantity of bubbles within solder that fixedly joins together a leadframe and a radiator. CONSTITUTION:Solder 3 is printed in the form of cross on a soldering region 2 of a radiator 1 using a metal mesh plate, and a leadframe is superimposed on the soldering region 2 of the radiator 1. An assembly consisting of the leadframe and the radiator 1 is heated in a heating furnace. Because of heating, the solder 3 radially spreads from the center owing to surface tension. Thereby, the solder 3 printed in the form of cross comes close to each other at the center but spreads outsides. When the solder 3 spreads and is flattened, bubbles remaining in the solder 3 are discharged, and hence the quantity of bubbles within the solder is decreased.

Title: Mask
Inventor: OKETA YUKIHIRO
IPC: G03F1/00
Filed: 1984-11-22
Abstract: PURPOSE:To make possible normalizing and to prevent the generation of a partial temp. difference of a resist by forming a light shielding film of a mask of a good heat conductive material. CONSTITUTION:The photomask 1 is constituted by depositing the light shielding film 3 atop a glass plate 2 and depositing the resist film 4 atop the film 3. The film 3 is formed of the two-layered construction in which the 1st layer 3a consists of copper and the 2nd layer 3b consists of chromium. Since the copper having excellent heat conductivity (having heat conductivity of about 6 times the heat conductivity of chromium at an ordinary temp.) is used in combination, the generated heat can be quickly diffused over the entire part of the light shielding film even if the heat is locally generated in the light shielding film or the glass surface in the stage of exposing with an electron ray and therefore the generation of the different temp. parts in the resist film owing to the generation of the heat is effectively prevented. The generation of the partial unbalance in the exposing sensitivity occurring from the nonuniform temp. is thereby prevented. The exact exposure patterning is thus attained.
