A bonded assembly is provided. The bonded assembly comprises: (a) a first substrate having a plurality of etched trenches defined in a first bonding surface; and (b) a second substrate having a second bonding surface. The second bonding surface is bonded to the first bonding surface with an adhesive and the adhesive is received, at least partially, in the plurality of etched trenches. Semiconductors chips bonded to a second substrate exemplify the advantages of the invention. The etched trenches allow the adhesive bond to be strengthened whilst avoiding increased surface roughening.
