Embodiment Construction
[0034] The present invention mainly provides a method for tempering the surface of crystal ingots, which can modify at least one surface of crystal ingots, especially the surface coated with a connection layer in the subsequent manufacturing process, by means of heat radiation conduction. In addition, the tempering method of the crystal rod surface of the present invention can reduce the phenomenon that the heat conduction in the crystal rod affects the concentration of thermal stress / thermal deformation in the crystal rod. It is worth noting that the "ingot" defined in the present invention can be interpreted broadly, and does not specifically refer to the manufacturer of a certain process, such as using an ingot (Ingot) formed by casting raw polycrystalline silicon, or cutting a crystal ingot. Square (squaring), cutting to form a block-shaped ingot approximately square columnar, or processed crystal ingots obtained by squaring and polishing are all applicable to the present i...
