Abstract: An improved method for constructing integrated circuit structures in which a buffer SiO2 layer is used to separate various components comprising ferroelectric materials or platinum is disclosed. The invention prevents interactions between the SiO2 buffer layer and the ferroelectric materials. The invention also prevents the cracking in the SiO2 which is commonly observed when the SiO2 layer is deposited directly over a platinum region on the surface of the circuit. The present invention utilizes a buffer layer of material which is substantially inert with respect to the ferroelectric material and which is also an electrical insulator to separate the SiO2 layer from the ferroelectric material and/or the platinum regions.

Abstract: 2082938 9118305 PCTABS00008 A light activated switching device (10) is disclosed in which the receipt of a light signal is used to switch a light beam between two output ports (14) and (16). The input light beam is reflected from an interface between two regions having different indices of refraction when the light signal is present. The reflected light beam then exits through the first output port (16). In the absence of the light signal, the two regions have the same index of refraction, and the light beam passes through both regions and exits through the second output port (14).
