    摘要: A plurality of p anode regions are formed at one surface of an n− substrate. A trench is formed in each p anode region. An ohmic junction region is formed between an anode metallic electrode and the p anode region. The p anode region has a minimum impurity concentration at a portion near the ohmic junction region which enables ohmic contact. A cathode metallic electrode is formed at the other surface of the n− substrate with an n+ cathode region interposed. Accordingly, a semiconductor device which has an improved withstand voltage and in which the reverse recovery current is reduced can be obtained.

    摘要: A problem in related art according to which an increase in leak current cannot be avoided in order to obtain a low forward voltage VF as forward voltage VF and reverse leak current IR characteristics of a Schottky barrier diode are in a trade-off relationship is hereby solved by forming a Schottky barrier diode using a metal layer comprising a Schottky metal layer of Ti including a small amount of Al. Consequently, a low reverse leak current IR can be obtained without causing a large increase in the forward voltage VF of pure Ti such that power consumption can be reduced by suppressing forward power loss and decreasing reverse power loss.

    摘要: In a method of obtaining a crystalline silicon film having high crystallinity at a low temperature and for a short time by using a catalytic element and using both a heat treatment and irradiation of laser light, a catalytic element which does not require a gettering step is used as the catalytic element for facilitating crystallization, so that a semiconductor device having high characteristics and high productivity is obtained. Specifically, a coating film of an element in group 14, such as germanium, which is the same group of the periodic table as silicon is formed on an amorphous silicon film formed on a glass substrate, a heat treatment at 550° C. for 4 hours is carried out, and further, irradiation of laser light is carried out, so that a crystalline silicon film is obtained. In the above structure, the element in group 14, which does not have a bad influence on TFT characteristics even if the element is left in the silicon film, is used, so that the semiconductor device having high characteristics and high productivity can be obtained.

    摘要: A method of manufacturing a semiconductor device includes providing semiconductor substrate having trenches and mesas. At least one mesa has first and second sidewalls. The method includes angularly implanting a dopant of a second conductivity into the first sidewall, and angularly implanting a dopant of a second conductivity into the second sidewall. The at least one mesa is converted to a pillar by diffusing the dopants into the at least one mesa. The pillar is then converted to a column by angularly implanting a dopant of the first conductivity into a first sidewall of the pillar, and by angularly implanting the dopant of the first conductivity type into a second sidewall of the pillar. The dopants are then diffused into the pillar to provide a P-N junction of the first and second doped regions located along the depth direction of the adjoining trench. Finally, the trenches are filled with an insulating material.

    摘要: A process for fabricating Zener diodes that does not require the use of photomasks. An oxide layer is grown on a silicon substrate which is doped with an N-type dopant. The substrate is subsequently implanted with a P-type dopant, forming a PN junction. The substrate is then metallized for connecting the Zener diode to other circuit components. Advantageously, the substrate is scribed after ‘seeding’ and before electroless metallization. Back-to-back Zener diodes formed in this manner are used as shunt circuits across individual lamp sockets in series-wired Christmas light strings to maintain current flow to each of the lamps of the light string when one or multiple lamps fail.

    摘要: A method of manufacturing a semiconductor device is disclosed in which a metallic deposit is stably formed on the anode side with small variation in film thickness, and plating is prevented on the cathode side without carrying out any additional processing on the cathode side. The processed anode side causes no interference in subsequent processing. Insulator films are used to cover a scribe line, as well as a field plate or an open electrode provided on a surface of a silicon substrate before Ni electroless plating of an aluminum electrode is performed to form a metallic deposit on the electrode.
