Latest Patents

One of Tsu-Hsing Yeh's latest patents is titled "Thin film magnetic transducer having center tapped winding." This invention features a magnetic circuit composed of nickel-iron layers that enclose portions of first and second windings. The design ensures that the conductor segments of each winding are separated in parallel planes, which helps avoid contact with the transition regions of the nickel-iron layers. This innovative approach results in a common inductance for each winding, enhancing the overall efficiency of the transducer.

Another significant patent is the "Semiconductor fabrication method for improved device yield by minimizing." This method addresses the challenges faced in fabricating bipolar semiconductor devices of large scale integration. By minimizing the formation of pipes that can lead to shorts or leakages, Tsu-Hsing Yeh's technique improves the reliability of semiconductor devices. The process involves creating nucleation sites for crystallographic defects in the base region before forming the emitters in bipolar transistors, ultimately converting these sites into harmless dislocation loops during the diffusion of the emitter impurity.
