Some embodiments of the invention include a connecting structure between a support and at least one die attached to the support. The die includes a number of die bond pads on a surface of the die. The connecting structure includes a plurality of via and groove combinations. Conductive material is formed in the via and groove combinations to provide connection between the die bond pads and bond pads on the support. Other embodiments are described and claimed.

A method for inserting a wire into a longitudinal groove of a semiconductor chip for the assembly thereof, the groove containing a pad made of a bonding material having a set melting point, comprises: in a positioning step, placing a longitudinal section of the wire along the groove, in forced abutment against the pad; and, in an insertion step, exposing a zone containing at least one portion of the pad to a processing temperature higher than the melting point of the bonding material and for a sufficient time to make the pad at least partially melt, and causing the wire to be inserted into the groove. The present disclosure also relates to a piece of equipment allowing the insertion method to be implemented.

The present invention provides a die bonding material containing the following component (A) and a solvent and having a refractive index (nD) at 25° C. of 1.41 to 1.43 and a thixotropic index of 2 or more, a light-emitting device including an adhesive member derived from the die bonding material, and a method for producing the light-emitting device. The die bonding material of the present invention is preferably used for fixing a light emitting element at a predetermined position. Component (A): a curable polysilsesquioxane compound having a repeating unit represented by the following formula (a-1) and satisfying predetermined requirements related to .sup.29Si-NMR and mass average molecular weight (Mw)
