Abstract: A small oven has a removable corrugated bottom platen. Bases of grooves formed by the corrugations slope towards one end of the platen when the platen is supported in the oven for use. As a result hot fat and other juices released during cooking drain off the platen making the platen less prone to contamination caused by burnt-on fat and therefore the platen easier to keep clean. The platen may have a planar cooking surface, in which case the platen is supported in the oven with the planar surface sloping towards the one end.

Abstract: A heating apparatus has an upper heating element and a lower hotplate. As part of the process of making integrated circuits, the heating apparatus is preheated using both the upper heating element and the hotplate. A substrate, which may be a semiconductor substrate or a photolithography mask, is then inserted into the preheated heating apparatus. Typically, the purpose of the heating is to cure the photoresist that is on the substrate and has already been exposed to a desired pattern. By having both the top heating element and the hotplate active during the preheating and during the curing, the photoresist is cured uniformly, which improves the pattern in the photoresist that occurs after a solvent has been applied to perform the selective removal of the photoresist in accordance with the exposed pattern. Subsequent use of the substrate results in integrated circuits made from semiconductor substrates.

Abstract: This invention is a thermal management method for efficient, rapid, controllable and uniform thermal management over a wide temperature range. The method integrates a thermal source, thermal sink and a thermal diffuser. According to the invention, a thermal diffuser is positioned stationary relative to the wafer surface and coupled to a thermal source and a thermal sink, which are also stationary relative to the wafer surface. The thermal sink comprises a heat-carrying media with a controllable temperature. The wafer is heated from a first processing temperature to a second processing temperature during a heating time interval and then cooled to the first processing temperature from the second processing temperature during a cooling time interval. During heating and cooling, the wafer is constantly held in a fixed position. Zonal control of the thermal source and non-uniform flow of the thermal sink enable sensitive mitigation of thermal non-uniformity on a heating surface.

Abstract: An object of the present invention is to provide a bump-bonding heating apparatus, a bump bonding method and a bump forming apparatus which do not involve large-sized apparatus configuration and which are easy to handle, and a semiconductor wafer in which bumps are formed by using the bump bonding method. The bump-bonding heating apparatus has a wafer turning member, a turning unit and a wafer heating unit.
