Abstract:
An integrated circuit device comprising:a semiconductor chip having a contact patch on a first side and having a predetermined thickness; a microstrip line board having: a first dielectric layer formed of dielectric material, a first conductive layer formed of electrically conductive material and bonded to a first side of the first dielectric layer and defining a plurality of conducting elements including a microstrip transmission line, a second conductive layer defining a first electrical ground plane formed of electrically conductive material and bonded to a second side of the first dielectric layer opposite the first conductive layer, and the microstrip line board having a pocket formed therein passing through the first conductive layer and through the first dielectric layer and the pocket being open on the first side and being closed on the second side by the second conductive layer and a portion of the second conductive layer being exposed at a bottom of the pocket and the pocket being of substantially the same size and shape as the semiconductor chip and the pocket receiving the semiconductor chip with the first side of the semiconductor chip disposed toward the second conductive layer; and a layer of bonding material disposed in the pocket between the contact patch of the semiconductor chip and the second conductive layer, and the layer of bonding material mechanically and electrically connecting the semiconductor chip to the second conductive layer.
