Abstract
Abstract The disclosure relates to memory cards having an electronic component housed in a cavity. The electronic support has a first base made of silicon, with a small thickness (between 50 and 100 microns) and a thicker (between 200 and 300 microns) second base, which is deposited on the first base and is formed by a material which is harder than silicon, such as cobalt, vanadium, titanium or ceramic.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
An electronic component support for a memory card which has a cavity to house said component, said support comprising a first silicon base of 50 to 100 microns thickness, one side of which is used as the substrate for the manufacture of the different elements of the electronic component, and comprising a second base of 100 to 300 microns thickness made of a harder material than silicon, and selecting from the group consisting of titanium, cobalt, vanadium, ceramic, and fiberglass-charged plastic, which is fixed to the other side of the first base, the second base being fixed to a film which acts as an element to close the cavity.
Claim 2
Dependent Claim
109 words
