Patent ID: 8290319

Claim:
A chip package, comprising: a set of semiconductor dies arranged in a vertical stack in a vertical direction, which is substantially perpendicular to a first semiconductor die in the vertical stack, wherein each semiconductor die, after the first semiconductor die, is offset in a horizontal direction by an offset value from an immediately preceding semiconductor die in the vertical stack, thereby defining a stepped terrace at one side of the vertical stack; and a ramp component, rigidly mechanically coupled to the semiconductor dies, wherein the ramp component is positioned on the one side of the vertical stack; wherein the ramp component is approximately parallel to a direction along the stepped terrace, which is between the horizontal direction and the vertical direction; and wherein the ramp component includes: an optical waveguide configured to convey an optical signal; and an optical coupling component configured to optically couple the optical signal to a semiconductor die in the set of semiconductor dies.
