Abstract: PROBLEM TO BE SOLVED: To provide an electronic device having an extremely shallow and abrupt junction with high dopant surface concentration by a microwave annealing process. SOLUTION: This method utilizes microwave energy to anneal an ion implanted wafer. The wafer can be substantially completely annealed by controlling time, power density and temperature area while limiting (and substantially preventing) diffusion of dopant in silicon. Thus, the wafer can be substantially completely annealed. In this manner, a semiconductor element scaled by high performance is provided. And, conditions are altered to give dopant profile (diffusion) to the silicon and can be controlled. In another aspect, a profile depth of less than 50nm and net doping concentration of 6nm to several ten times or more is changed in the semiconductor wafer and surface concentration of the dopant exceeds about 1×10 /cm in the method for forming a PN junction.

Abstract: The described invention is directed to microwave methods for burning-in, electrical stressing, thermal stressing and reducing rectifying junction leakage current in fully processed semiconductor chips individually and at wafer level, as well as burning in and stressing semiconductor chip packaging substrates and the combination of a semiconductor chip mounted onto a semiconductor chip packaging substrate. Microwaves burn-in devices in a substantially shorter period of time than conventional burn-in techniques and avoid the need for special workpiece holders which are required by conventional stress and burn-in techniques. Additionally, microwave methods are described for reducing the leakage current of rectifying junctions, such as PN junctions and Schottky barrier diode junctions of semiconductor devices on fully processed semiconductor chips and wafers.
