Title: The Innovations of Dong-Sing Wuu

Introduction

Dong-Sing Wuu is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of technology, particularly in the development of advanced manufacturing methods for inkjet print heads and light-emitting diodes (LEDs). With a total of nine patents to his name, Wuu's work has greatly influenced the efficiency and cost-effectiveness of these technologies.

Latest Patents

One of Wuu's latest patents is a manufacturing method of monolithic integrated thermal bubble inkjet print heads. This innovative method utilizes semiconductor manufacturing technologies to configure various elements within the print head on a single substrate. The ink channels are formed on the top surface of the substrate using anisotropic etching techniques, while the ink slot is created on the back surface. The energy transducer and orifice plate are then formed above the ink channels using coating and etching techniques. This method enhances production efficiency and reduces costs by eliminating the need for precision alignment joints typically required in conventional inkjet print heads.

Another notable patent is for a light-emitting diode with a metal-coated reflective permanent substrate. The manufacturing process involves growing a light-emitting region on a temporary substrate, bonding it to a metal-coated reflective permanent substrate, and subsequently removing the temporary substrate. The reflective metal layer also acts as a bonding agent. During the heating process in a wafer bonding tool, the differing thermal expansion coefficients between stainless steel and graphite help to apply pressure, ensuring a strong bond between the LED element and the permanent substrate.
