发明名称 Integrated circuit power device with transient responsive current limiting means
摘要 An integrated circuit power device includes many cell blocks which are electrically connected in parallel, with each of the cell blocks including at least one cell such as a MOSFET, electrically connected in parallel. A transient responsive current limiting means, such as a resistor/capacitor circuit, is electrically connected to each cell block, so that the leakage current into defective cell blocks is maintained below a predetermined level without limiting the operating speed of the device. An operable integrated circuit power device is thereby obtained, notwithstanding a defective cell block. The circuit resistors are preferably formed using the same mask and material as the gate. The circuit capacitors and common gate electrode are preferably formed using the same mask and material as the source electrode. The use of common materials eliminates the need for extra fabrication steps.
