ABSTRACT:
A method for manufacturing a lead frame comprises the steps of covering, with a cover film, a die to which an electronic device is attached and a conducting section of a lead section to be electrically connected to the die, covering the whole of the die and lead section and the cover film with an inorganic protective film, and removing the cover film and the protective film formed over the cover film to partly expose the die and the conducting section for electric connection.
