A film-on-wire spacer covers an entire upper surface of a lower electronic
component. Accordingly, an upper electronic component is supported above
bond pads and lower bond wires of the lower electronic component. This
decreases the stress on the upper electronic component, e.g., during
wirebonding, and thus decreases the chance of cracking the upper
electronic component. Further, the lower bond wires are enclosed in and
protected by the film-on-wire spacer. Further, the film-on-wire spacer is
thin resulting in a minimum height of the stacked electronic component
package.
