At that size, it expects to make use of new materials and high-k dielectrics. |
In many photonic structures composed of two or more dielectrics, the absolute value of the refractive index contrast is critical to performance. |
The dielectric properties of composite dielectrics generally are a weighted average of the individual component properties. |
The new materials include dielectrics and dopants, which are commonly used in high-volume semiconductor manufacturing. |
However, in the attempt to pace up with this evolution, thinner on-chip metals and dielectrics have a troubling effect on the Q factor of on-chip passives. |
This volume is more oriented to technological aspects, and considers dielectrics with very high permittivity and ferroelectrics. |
