Varmetrådssensor med submillimeterstørrelse og tilhørende fremgangsmåde til fremstilling deraf

摘要

The invention relates to a submillimeter-sized hot-wire sensor (1) comprising a substrate (10), two support rods (11, 12), a metal wire (13) extending between the two ends of the support rods (11, 12), and electrical contacts (14, 15) disposed on the support rods, said contacts each being linked to one of the ends of the wire (13). The metal wire comprises at least two layers of metal materials, one of said layers being made of a material exhibiting a residual stress under tension and the other layer being made of a material exhibiting a residual stress under compression. The thicknesses of these metal layers are adapted so as to compensate the residual stresses between the various layers.
