Abstract: PURPOSE:To block a soft error of a semiconductor device due to alpha rays, by adhering a  film at a fixed region on a chip of a semiconductor device, dripping an alpha ray blocking  material with a desired thickness thereon and hardening. CONSTITUTION:In a wafer work process, e.g. a polyimide film 201 is applied on a place  where is the part changing into a chip in the further and wherein alpha rays must be  blocked. This is applied over the entire surface of the wafer 202 by a rotation applying method, next the polyimide on an unnecessary part is removed by a photo resist  method with a hydrogeneous etchant. Next, the wafer 202 is changed into a chip 203  thereafter being mounted onto a normal base ribbon 204. Thereafter, after finishing a  normal bonding process, a polyimide 205 dissolved in a solvent is dripped again on this polyimide film 201. A polyimide film 90-150mum thick is formed taking a care that this  polyimide 205 does not bulge out of the previously provided polyimide film 201 by the  surface tension thereof. A polyimide film obtained in such a manner can sufficiently  block alpha rays up to alpha rays with high energy as an alpha ray blocking material. A bonding  connection part 207 is covered only with a mold resin 206 by hardening the polyimide in this state and sealing it by a mold resin 206. Therefore, even after a temperature cycle test, a good conduction state can be maintained without the removal of the bonding connection.
