    摘要: A method for minimizing slip line faults on a surface of a semiconductor wafer that has been obtained using a transfer technique. The method includes heating the semiconductor wafer from an ambient temperature to a first higher temperature and pausing the heating at the first higher temperature for a time sufficient to stabilize the wafer. Then the wafer is heated further from the first higher temperature to a target higher temperature during a predetermined time interval. The further heating during an initial portion of the time interval is conducted at a relatively low heating rate and the heating during a final portion of the time interval is conducted at a relatively higher heating rate to thus minimize slip line faults in the surface of the wafer.

    摘要: A method for heat treating a multilayer semiconductor wafer having a central region and a peripheral edge each having a surface. The method includes selecting thickness values for the layers of the wafer to provide substantially equivalent heat absorption coefficients both in the central region and the edge of the wafer. This results in a substantially equivalent temperature being attained over the surface of the central region and the peripheral edge during thermal treatment. In turn, that prevents the appearance of slip lines on those surfaces while also preventing deformation of the wafer due to the thermal treatment. To achieve the desired thickness, layers or portions of layers can be selectively added or otherwise provided upon the central region or peripheral edge of the wafer, or on both, to modify the heat absorption coefficient of the wafer.
