    Abstract: A thermal plate for a substrate support assembly in a semiconductor plasma processing apparatus, comprises multiple independently controllable planar thermal zones arranged in a scalable multiplexing layout, and electronics to independently control and power the planar heater zones. Each planar thermal zone uses at least one Peltier device as a thermoelectric element. A substrate support assembly in which the thermal plate is incorporated includes an electrostatic clamping electrode layer and a temperature controlled base plate. Methods for manufacturing the thermal plate include bonding together ceramic or polymer sheets having planar thermal zones, positive, negative and common lines and vias.

Next, inserting the first wafer into a bonder module and holding the first wafer by an upper chuck assembly (412) so that its first surface with the cured first adhesive layer faces down. Next, inserting the second wafer into the bonder module and placing the second wafer upon a lower chuck assembly (414) so that the second adhesive layer faces up and is opposite to the first adhesive layer. Next, moving the lower chuck assembly upwards and bringing the second adhesive layer in contact with the cured first adhesive layer, and then curing the second adhesive layer.

    Abstract: This method for estimating the depth of latent scratches in SiC substrates includes an etching step, a measurement step, and an estimation step. In the etching step, a SiC substrate in which at least the surface is formed from single crystal SiC, and which has been subjected to machining, is subjected to heat treatment under Si atmosphere to etch the surface of the SiC substrate. In the measurement step, the surface roughness or the residual stress of the SiC substrate which has been subjected to the etching step is measured. In the estimation step, the depth of latent scratches or the presence or absence of latent scratches in the SiC substrate before the etching step are estimated on the basis of the results obtained in the measurement step.
