Title: Innovations of Hideki Harano
Introduction
Hideki Harano is a notable inventor based in Gunma, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that enhance the reliability and efficiency of semiconductor devices.
Latest Patents
One of his latest patents is a method of manufacturing a semiconductor device aimed at improving reliability. This method involves providing a semiconductor substrate with an insulating film that has an opening exposing multiple electrode pads. A flux member containing conductive particles is arranged over each electrode pad, followed by the placement of solder balls over these pads via the flux member. The solder balls are then heated to bond them to the electrode pads, with the opening of the insulating film being smaller than the diameter of the solder balls.
Another significant patent is for a semiconductor device and its manufacturing method. This device includes a semiconductor substrate, a pad electrode, a post electrode made of a copper film, and a solder ball electrode made of a ternary alloy containing tin. The design features a terminal connected to the solder ball electrode on a wiring board, with a sealing material filling the gap between the semiconductor substrate and the wiring board. The post electrode is designed with a cylindrical stem portion and an overhanging portion, ensuring effective contact with the sealing material.
