    摘要: An integrated circuit including a wafer having a GaAs substrate, an un-doped GaAs layer, and a GaAs active layer. This active layer may have an HEMT structure to improve its operation speed. Also, the substrate may a multi-layer structure to form a three dimensional capacitor. At least one mesa portion is formed on the substrate by removing a portion of the un-doped GaAs layer and GaAs active layer. A source electrode, for example, is formed on the mesa portion, and a ground electrode is formed on an exposed surface of the substrate. These electrodes are connected to each other by means of a wiring metal layer. As a result, the source electrode is easily grounded without using a long bonding wire.

    摘要: A highly magnetic Hall element comprising a substrate, a Hall element chip mounted on the substrate, and a magnetic member interposed between the substrate and the chip. The magnetic member increases the coercive force of the element, and is formed by laminating resin layers mixed with powder having a high magnetic permeability, one upon another, by stencil printing on that side of a semiconductor wafer in which a Hall element is mounted. The wafer and the magnetic member are diced together, to provide a Hall element chip. The magnetic member formed on the Hall element chip is adhered to substrate, with half-cured surface put in contact with the substrate.
