Latest Patents
Kaihsiang Yen's latest patents encompass groundbreaking methods for fabricating 3-dimensional solenoids. The first patent describes a technique that utilizes CMOS fabrication technology and a back-end process without the need for photomasking. In this method, two suspended arms crafted from a bi-layered metal structure are connected to an inductor coil made of AlCu. Upon the removal of the insulating layer of silicon dioxide, the ends of these arms curve upwards, subsequently elevating the inductor coil into a 3-dimensional configuration.
The second patent introduces a method for fabricating a tunable 3-dimensional solenoid. This method also employs CMOS fabrication technology without photomasks. It utilizes curved arms made of a bi-layered metal structure, designed to connect to the inductor coil formed of AlCu. The removal of the silicon dioxide insulating layer allows the ends of the curved arms to raise the inductor coil away from the semiconductor substrate. By applying electrical voltage to the electrodes on the substrate, an electrostatic force is created, enabling further control over the inductor coil's length by manipulating the curvature of the arms.
