Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JPS5575231
Kind Code:
A
Abstract:
PURPOSE:To reduce the number of parts by piercing a tubular indulator to guide a gate-conductive wire which constitutes a thyristor, connecting one end of the wire to a gate electrode, positioning the other end of the wire at the outside, and sealing the pierced portion by a metalized layer. CONSTITUTION:In a tubular insulator 4 having a hole to guide a gate-conductive wire 9 comprising an elastic body, is provided a thyristor element 1 comprisisng a positive electrode 1a as an upper layer, a negative electrode 1b, and a gate electrode 1c as a lower layer. Then, a positive-electrode conductor 2 is fixed to the positive electrode 1a and is supported by the first and second welding rings 6 and 7 which are attached to the top of the insulator 4. One end of the gate-conductive wire 9 is fixed to the gate electrode 1c. Then, the other end of the conductive wire 9 is taken out by way of the hole provided in the insulator 4. The inside of the hole is sealed by a metalized layer 12 comprising an Mo-Ni layer and an Ag-Cu layer. Then, a negative-electrode conductor 3 having a cut-out portion to enclose the central portion of the conductive wire 9 is attached to the electrode 1c and is supported by a diaphragm 5 provided at the bottom of the insulator 4.
