Abstract
Current sensing resistors and a method of manufacturing the same are disclosed in the present invention. A composite material is firstly provided in the method. Then, a first portion of an alloy substrate of the composite material is removed along a first direction to form a plurality of first trenches. Next, a second portion of the alloy substrate of the composite material is removed along a second direction to form a plurality of second trenches, and a third portion of the alloy substrate of the composite material is further removed along the first direction to form the current sensing resistors. The current sensing resistors with small dimensions and an extremely low temperature coefficient of resistance can be produced rapidly by the method of the present invention.
