Abstract: Disclosed a heat shield and a monocrystalline silicon growth furnace using the same. The heat shield is arranged in an upper portion of a melt crucible in the monocrystalline silicon growth furnace, and comprises a shield wall and a shield bottom provided with a window for pulling melt through. The shield bottom comprises a top layer, a bottom layer and a side wall. The side wall is connected between the top and bottom layers and encloses the window.
