WIPO Patent Application WO/2019/124892
Kind Code:
Disclosed is a semiconductor lead frame coating composition for electromagnetic wave shielding. The objective of the semiconductor lead frame coating composition for electromagnetic wave shielding according to an embodiment of the present invention is to provide a composition for a semiconductor lead frame coating for shielding from electromagnetic wave interference that may occur in an electronic component of a semiconductor device. To this end, the present invention relates to a coating liquid composition used for spray coating to form an electromagnetic wave shielding layer on a semiconductor lead frame. As a result, the present invention relates to a semiconductor lead frame coating composition for electromagnetic wave shielding, which may have a function of shielding from electromagnetic interference generated in a semiconductor device, enables an economical and thin coating layer to be obtained as compared with a sputtering method which is a conventional method of forming a high-priced coating layer, and is advantageous in mass production and can simplify the processing thereof.
