Abstract

First and second electrodes are formed on opposite sides of a relatively fragile, thin, flat wafer of a semi-conductor material having at least one p-n junction. The first and second terminals extend externally of the housing in which the semi-conductor wafer is enclosed. The second terminal is electrically connected to the second electrode. A flexible lead connects the first terminal to the first electrode. The flexible lead includes an elongated conductive member having at least two reentrantly bent flexible legs which have their ends spaced from one another. The flexible lead further includes an elongated lead extending perpendicular from a central region of the elongated conductive member in a direction opposite from the direction in which the flexible legs extend. The outer surfaces of the at least two legs are electrically and mechanically connected to the first electrode.

Dependent claims

A flexible lead for a semi-conductor device;

said semi-conductor device comprising:
a single, relatively fragile, thin, flat wafer of a semi-conductor material having at least one p-n junction;
first and second electrodes on opposite surfaces of said semi-conductor wafer;
a housing enclosing said semi-conductor wafer;
first and second terminals extending externally of said housing;
said second terminal being electrically connected to said second electrode;
said flexible lead connecting said first terminal to said first electrode;
said flexible lead including an elongated conductive member having a main body which has at least two reentrantly bent flexible legs extending from a flat body section and which are disposed in a common plane which is spaced from and parallel to said flat body section;
said legs having ends which face one another and which are spaced from one another;
said flexible lead having an elongated lead extending perpendicularly from a central region of said main body and extending in a direction opposite from the direction of said common plane, the outer surfaces of said at least two legs being electrically and mechanically connected to said first electrode.
