Latest Patents

One of Yi-Shiau Chen's latest patents is titled "Microelectronic 3-D solenoid of circular cross-section and method for fabrication." This invention describes a microelectronic 3-dimensional solenoid that features a substantially circular or oval cross-section. The solenoid is constructed using a pre-processed semiconductor substrate and includes two supports that are spaced apart on the substrate's top surface. Each support has a bottom end attached to the substrate, while an inductor coil connects to the top ends of the supports. The inductor coil is made from a bi-layer metal laminate, consisting of an inner metal layer and an outer metal layer, which have different coefficients of thermal expansion.

Another notable patent by Chen is the "Method for fabricating 3-dimensional solenoid and device fabricated." This method utilizes CMOS fabrication technology and a back-end process that does not require photomasking. The process involves two suspended arms formed from a bi-layered metal structure, which connect to an inductor coil made of AlCu. When the insulating layer of silicon dioxide is removed, the free ends of the arms curve upward, raising the inductor coil into a 3-dimensional structure.
