Abstract
Various capacitive isolation structures which can be readily incorporated into existing IC manufacturing procedures. An illustrative method embodiment for forming an isolation capacitance includes: (a) forming a recess on a surface of an integrated circuit substrate, the recess having a bottom surface; (b) coating the bottom surface with an insulating layer; (c) overlaying a bottom electrode on the insulating layer; (d) filling the recess with a bulk insulator having a minimum thickness no less than half a depth of the recess; and (e) depositing a top electrode above the bulk insulator.
