A method for manufacturing a structure includes: supplying an active element provided with a front and rear face connected by a contour; assembling the front face and a main face of a support; filling a space of interconnections between the front face and the main face with glue. The method also includes, before the assembling, forming, by a method other than a plasma method, a first passivation layer covering the contour, and made from a first compound that makes it possible to limit the wetting of said contour by the glue regarding the front face and the main face.

Method for manufacturing a structure

A method for assembling components includes assembling a first component including solder bumps with a second component including connectors. The assembly of the components is preceded by pre-treating the first and second components wherein the solder bumps are contacted with a pre-treatment liquid configured to at least partially remove an oxide layer initially present on the solder. The pre-treatment liquid is an aqueous solution containing carboxylic acids or polycarboxylic acids. The assembly of the components is carried out after the pre-treatment in the absence of liquid or gas flux.
