| titleOfInvention | Package for housing semiconductor element and method of manufacturing the same |
| abstract | PROBLEM TO BE SOLVED: To improve the airtightness of a semiconductor package by preventing the occurrence of cracks and chips on the inner surface of a concave portion of a base, and to allow a semiconductor element to be housed therein for a long period of time. In addition to operating normally and stably, resin burrs generated on the end of the external lead terminal exposed in the concave portion and dust on the inner surface of the concave portion may cause adhesion to semiconductor elements such as CCD after sealing. To prevent the occurrence of wire bonding failure. A concave portion (3) on the upper surface of a base body (1) has an inner surface (4) inclined at an angle of 10 to 20 ° so that an inner dimension gradually decreases from an upper surface side opening to an external lead terminal (5). And the arithmetic average roughness Ra of the inner surface 4 is 0.05 to 0.4 μm m. |
