Pressure-sintering method employing deformation uptake means

A method for fixing an attachment object to a patterned object by pressure-sintering, wherein the attachment object becomes fixed to an attachment side of the patterned object and wherein the patterned object comprises a patterned side facing away from the attachment side, the patterned side including a plurality of protrusions with tip portions, the method including:

• providing a sintering material between the attachment object and the attachment side of the patterned object;
• arranging the patterned object and the attachment object in a sintering tool, wherein the patterned object is arranged at a first tool side of the sintering tool and the attachment object is arranged at a second tool side of the sintering tool;
• arranging a deformation uptake means between the first tool side and at least a fraction of the tip portions, wherein the deformation uptake means is made of a deformation material having a lower yield strength and/or a lower hardness than the tip portions;
• a solidification step including pressing the patterned object and the attachment object towards each other for densifying the sintering material and applying heat to the sintering material, thereby sintering the sintering material, forming a sinter layer between the attachment side and the attachment object and forming an assembly comprising the attachment object and the patterned object;
• and
• removing the deformation uptake means from the assembly.
