SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes a functional block unit, external terminals and, and an external resin sealing body. The functional block unit includes an internal resin sealing body having an edge and an opposite edgeb. The edge side of the internal resin sealing body covers a first end of an internal terminal, but does not cover a second end of the internal terminal. The edge side of the internal resin sealing body covers a first end of an internal terminal, but does not cover a second end of the internal terminal. The external resin sealing body covers the root portion and a portion of the middle portion of the external terminal, but does not cover the terminal portion of the external terminal. The functional block unit and the external terminals and are integrally connected together and sealed by the external resin sealing body.

主权项

1. A method of manufacturing a semiconductor device, comprising:
a functional block preparation step of preparing a functional block unit, wherein the functional block unit includes a semiconductor element, at least one internal terminal having a first end and a second end and electrically connected to the semiconductor element, and an internal resin sealing body covering the semiconductor element and the first end of the at least one internal terminal but not covering the second end of the at least one internal terminal; an external terminal preparation step of preparing an external terminal having a third end and a fourth end; a connection step of connecting the third end of the external terminal to the second end of the at least one internal terminal; and an external resin sealing step of, after the connection step, covering the second end of the at least one internal terminal and the third end of the external terminal with a resin, but not covering the fourth end of the external terminal.
