An apparatus for heating a substrate of a semiconductor device includes a hot plate, on which a semiconductor substrate is placed, and a heater for heating the hot plate. The hot plate is preferably a composite plate including a plurality of plates having different thermal conductivities from each other. For example, a first plate adjacent to the heater can be made of aluminum, which has a relatively high thermal conductivity. A second plate, laminated on top of the first plate, can be made of titanium or stainless steel, which both have a thermal conductivity lower than aluminum. A composite hot plate as disclosed herein is better able to maintain a constant temperature and a uniform temperature distribution in order to more uniformly heat a substrate and to reduce an amount of energy required for the heating process. In addition, the reliability and productivity of the semiconductor device manufactured by the apparatus can be improved.

A composite board is made from waste medium density fiber (MDF) board or waste particle board that includes solid urea formaldehyde. The waste board is chopped and milled into particles having a size between 20 mesh and 150 mesh, creating a waste flour. After removing moisture from the waste flour, the dried waste flour is mixed with a thermoplastic to bind and encapsulate the waste flour. Internal lubricants are added to improve the flow characteristics of the blended material, and external lubricants are added to present sticking of the mixture to an extruder or mold. Mineral fillers are added to improve the flexural modules of the composite board, and a plasticizer can be added to improve the physical properties or mechanical characteristics of the mixture. An ultraviolet absorber, a biocide, and a pigment can also be added. The blended material is extruded or molded into a desired shape.
