Resistive heater for thermo optic device |
摘要 |
Resistive heaters formed in two mask counts on a surface of a grating of a thermo optic device thereby eliminating one mask count from prior art manufacturing methods. The resistive heater is comprised of a heater region and a conductive path region formed together in a first mask count from a relatively high resistance material. A conductor formed from a relatively low resistance material is formed directly on the conductive path region in a second mask count. Thermo optic devices formed by these two mask count methods are also described.
