Abstract: A method of producing a semiconductor device having a heat dissipating metal layer wherein the number of patterning steps is reduced, laser dicing produces a better profile, and first and second matal layers are prevented from separating from each other, and a semiconductor device produced by the method. The number of patterning steps is reduced by employing a flat exposure step for photoresist with mask alignment, A better appearance is obtained by forming the metal layers which connect the semiconductor devices with each other from a first metal layer having a lower melting point and a second metal layer having a higher melting point and severing the first metal layer and the second metal layer successively, from the first metal layer side. A second metal layer is prevented from peeling by preventing oxidation of the plated feeder layer through plating of the second metal layer.

Abstract: An electroplating apparatus includes an electroplating tank having a generally flat base on which a semiconductor substrate may be placed with a surface to be electroplated oriented upwardly. A first seal seals a tank body to the flat base and a second seal seals the tank body to a peripheral portion of the surface of the semiconductor substrate. A substantially sealed volume adjacent the surface of the semiconductor substrate is produced. A gas supply tube for pressurizing the volume and an electrolyte discharge arrangement for discharging electrolyte from the volume when pressurized by a gas introduced through the gas supply tube are also provided. The discharge tube extends through a wall of the tank body to a position immediately above the surface of the semiconductor substrate within the volume.

Abstract: A method for producing semiconductor chips includes preparing a semiconductor wafer having opposite front and rear surfaces and active semiconductor devices disposed in the semiconductor wafer at a part of the front surface, attaching a glass plate to the front surface of the semiconductor wafer, thinning the semiconductor wafer to a desired thickness from the rear surface, forming a first radiating layer over the rear surface of the semiconductor wafer, selectively forming a second radiating layer on the first radiating layer using, as a mask, a photoresist pattern covering portions of the first radiating layer opposite dicing regions, removing the semiconductor wafer from the glass plate, and cutting through the wafer and the first radiating layer with a dicing blade to produce a plurality of semiconductor chips. In this method, since the first radiating layer supports the thin wafer, the glass plate can be removed before the dicing process.
