A passive surface mount part such as a capacitor or a resistor is employed to attach a first substrate to a second substrate, or a semiconductor device to a substrate, for an electrical circuit assembly. Applicable forms of substrates include a printed circuit board such as a motherboard and a daughterboard, and applicable forms of semiconductor devices include an integrated circuit. In an aspect, a low profile attachment is provided forming a planar structure. Space is conserved, signal transmission is provided, and electrical performance is increased. In another aspect, a standoff is defined between the substrates setting the substrates apart a desired distance, compensating for any surface irregularities, increasing thermal separation, and increasing interconnect flexibility. As an application, the standoff defined between the substrates can be utilized for a structure such as optical glass structure to be situated between the substrates for use with an optical circuit assembly.
