<p>A method of making a microwire characterized in that a wire blank (1) for the microwire (2) in the course of its drawing is alternatively rolled over in relation to the drawing axis (B-B) by at least half lengths of the circumference of the wire blank (1). The device for implementation of the method comprises a casing (3), a drawing die (4) and a mechanism for pulling the microwire through the drawing die (4). The drawing die (4) consists of two parts (5 and 6) interacting with the wire blank (1) of the microwire (2) during its drawing between them, each of those parts being provided with a calibrating surface (8). The parts (5 and 6) of the drawing die (4) are mounted in the casing (3) with the possibility of reciprocating synchronous displacements in mutually parallel planes, the calibrating surfaces (8) of both parts (5 and 6) of the drawing die (4) being flat and parallel to each other and to the drawing axis (B-B). The method and the device for making microwire can be used for production of semiconductor devices and integrated microcircuits and can be used as well for improving the quality of the surface of microwires compared to those produced by means of other processes and devices. </p> |
