ABSTRACT:
Electrically conductive elements on two substrates can be electrically interconnected by an adhesive tape containing electrically conductive particles, most of which are substantially uniformly spaced from their six nearest neighbors. Preferably the particles are spherical and of substantially equal diameter slightly exceeding the thickness of the adhesive layer. The adhesive tape can be made by forming a dense monolayer of the particles, covering a stretchable adhesive layer with that dense monolayer, biaxially stretching the adhesive layer to separate each particle from other particles of the monolayer, and then embedding the particles either into that adhesive layer or into the adhesive layer of another tape.
