Wafer holder, and wafer prober and semiconductor manufacturing apparatus provided therewith

Abstract

A wafer holder that includes a cooling module for rapid cooling, that can further improve the heating uniformity of a wafer, and that can be appropriately used with a wafer prober, a coater/developer, or the like. The wafer holder includes a mounting stage arranged to mount a wafer on a mounting surface, a heat generator 1 arranged to heat the mounting stage, and a cooling module arranged to cool the mounting stage, wherein an outside diameter of the cooling module is smaller than an outside diameter of the mounting stage, and the heat generator 1 attached to the mounting stage is positioned further to the outside than the cooling module. Along with the heat generator 1, a supplementary heat generator may be positioned between the cooling module and the mounting stage or on a surface of the cooling module opposite the mounting stage.
