摘要:
A semiconductor device includes a first conductivity type layer and a second conductivity type layer, which are alternately and repeatedly positioned, adjacent to each other, in a column-like fashion on a first conductivity type substrate. The balance of the net charge amount of the impurity between the first conductivity type layer formed under a second conductivity type base layer in the termination region of the semiconductor device and the second conductivity type layer adjacent to the first conductivity type layer is imbalanced in comparison to the balance of the net charge amount of the impurity between the first conductivity type layer in the device-forming region of the semiconductor device and the second conductivity type layer adjacent to the first conductivity type layer.

This semiconductor device an epitaxial layer of a first conductivity type formed on a surface of the first semiconductor layer, and a base layer of a second conductivity type formed on a surface of the epitaxial layer. A diffusion layer of a first conductivity type is selectively formed in the base layer, and a trench penetrates the base layer to reach the epitaxial layer. A gate electrode is formed in the trench through the gate insulator film formed on the inner wall of the trench. A first buried diffusion layer of a second conductivity type is formed in the epitaxial layer deeper than the bottom of the gate electrode. A second buried diffusion layer connects the first buried diffusion layer and the base layer and has a resistance higher than that of the first buried diffusion layer.

In a thermal cutting machine such as plasma cutting machine or a laser cutting machine, control of the moving speed of a cutting head (24) is improved so as to increase throughput of the cutting machine with increase in cost restricted. Products are cut out one by one from a plate member (14) while a cutting head (24) is moved relative to the plate member (14) on a table (12). In this process, when the cutting head (24) is fast-forwarded without performing cutting to a position at which cutting of each product starts, the speed of movement in the direction (Y-axis direction) along a short side of the table (12) is controlled at a speed higher than that of the movement in the direction (X-axis direction) along a long side of the table. The pattern of a sequence of cutting out the products from the plate member (14) is a meandering pattern in which reciprocation in the Y-axis direction dominates and the movement in the X-direction is one time one way. Exhaust chambers are arranged in the X-axis direction in the table (12), and the exhaust chambers are driven as the cutting head (24) moves in the X-axis direction.

A P++-type first diffusion layer is formed by diffusing P-type impurities on a front side of an N−-type semiconductor substrate, and an N-type fourth diffusion layer which is shallower than the first diffusion layer is formed by diffusing N-type impurities on the front side, and a P-type second diffusion layer is locally formed in a ring-shape so as to be exposed on the lateral side by diffusing P-type impurities on the back side, and P-type impurities are diffused on the back side of the substrate and a P+-type third diffusion layer is locally formed so as to be distributed inward from the second diffusion layer and not to be exposed to the lateral side, and the P-type second diffusion layer and the P+-type third diffusion layer are formed in the two-stage structure, thereby various characteristics can be improved.

A jog dial server monitors an operation notification by a jog dial, then decides the operation based on the operation notification, and executes the decided operation as a jog script engine. The jog dial server loads a script file describing status transition of the jog dial in the script language at the time of start-up, then reads the status transition, and operates in accordance with the status transition thus read. Thus, an information processing device is provided which enables extension of the operation with respect to an application incompatible with the jog dial.

A wireless communication RF circuit includes a transmitting-and-receiving antenna, a modulator circuit, an SPST switching circuit, and a demodulator circuit, which are arranged in a sequence. Upon signal reception, the SPST switching circuit is switched ON, and the demodulator circuit extracts a signal wave from a signal received by the antenna and outputs the signal wave to a control circuit. Upon signal transmission, the SPST switching circuit is switched OFF, and the modulator circuit mixes transmission data supplied from the control circuit with a carrier and outputs the carrier to the antenna. Only a single antenna is required. Upon signal reception, the influence of the modulator circuit is negligible. Upon signal transmission, the SPST switching circuit is switched OFF, thus the effect of the demodulator circuit is negligible, which greatly reduces loss.
