Abstract: This relates to correcting the actual absolute capacitance values of electrodes of non-optimized geometric shapes that are connected to electronic circuits. To correct the actual absolute capacitance values, a prediction model can first be determined by carrying out nonlinear regression on the basis of actual values of absolute capacitance values from the electrodes and from a probability density image from idealized electrodes for a plurality of object positions. The prediction model can then be applied to the actual absolute capacitance values to obtain a probabilities densities image for the actual absolute capacitance values, considered to be corrected absolute capacitance values used for the detection of the object.

Abstract: A novel apparatus for bonding of two polished substrates includes a plasma source in a ultra-high vacuum (UHV) chamber and a wafer-guiding element to control and guide wafers in the UHV chamber, where after a plasma activation process the wafers are guided and pressed against each other to form a covalent bond between wafer surfaces. The plasma activation process involves deposition of mono-layer or sub-monolayer metallic atom on the surface of substrates. After deposition of metallic layers, a high-force actuation presses the wafers and forms a covalent bond between the wafers. Then, the bonded wafer pair is ion-sliced or thinned to form single crystalline optical thin film. An annealing process oxidizes the deposited metallic layers and produces optically-transparent single crystalline thin film. An optical waveguide may be fabricated by this thin film while utilizing an electro-optic effect to produce optical modulators and other photonic devices.
