Title: Innovations by James L Rutledge

Introduction

James L Rutledge is a notable inventor based in Austin, TX, who has made significant contributions to the field of semiconductor technology. With a total of 5 patents to his name, Rutledge has developed innovative methods that enhance the efficiency and effectiveness of semiconductor devices.

Latest Patents

Among his latest patents is a method for testing a semiconductor device, which involves a test substrate that includes a plurality of solder bumps. This substrate is designed to test a die that can function as either a wire-bonded device or a flip-chip device. The die features test pads that provide redundant electrical connections to bond pads. During testing, the solder bumps make contact with the test pads, and depending on the intended use of the die, the bumps either remain on the test substrate or are transferred to the die. This innovative approach allows for the use of common process flows and die layouts for different device types, ultimately saving on manufacturing and design costs.

Another significant patent by Rutledge is for a substrate that facilitates the transfer of bumps. In this invention, a first pattern of bumps and a second pattern of bumps are formed on a substrate. During the transfer process, only the bumps from the first pattern are transferred to the pad extensions of a device, while the bumps from the second pattern remain unaffected for later use. This method showcases Rutledge's ability to streamline processes in semiconductor manufacturing.
