摘要： PROBLEM TO BE SOLVED: To provide a power MOSFET for amplifying high-frequency power in which the breakdown voltage of a drain does not drop even when the MOSFET is operated at a low power supply voltage. SOLUTION: Since a p-type semiconductor area 20 which has the same conductivity as that of a semiconductor substrate 1 (epitaxial layer 1B) and contains an impurity at a high concentration is formed immediately below a contact area 7 comprising part of the drain area of a power MOSFET (Q), the junction breakdown of the drain is prevented by generating an avalanche yield between the semiconductor area 20 and the substrate 1(epitaxial layer 1B) before the electric field intensity in an offset area 6 at the end section of a gate electrode 4 reaches a breakdown value.

摘要： PROBLEM TO BE SOLVED: To efficiently manage an accumulation means by presenting available remaining capacity of the accumulation means as a numerical value indicating capacity or a program accumulation enabled time in a digital broadcast accumulation device comprising the data accumulation means such as an HDD. SOLUTION: The available remaining capacity of the accumulation means is computed by comparing a transmission rate of program data with the accumulation means and presented to a user, thereby efficiently managing the accumulation means. Furthermore, the program accumulation enabled remaining time is calculated from a transmission rate of the accumulation designated program and the available capacity and presented to the user, so that the user can intuitively know the available capacity. Moreover, the user is enabled to select video data of the program to be accumulated in the accumulation means or is enabled to set a coding rate of video data and audio data, thereby accumulating all the programs designated by the user.

摘要： PROBLEM TO BE SOLVED: To efficiently manage a storing means by presenting the usable residual capacity of the storing means with a numerical value showing the capacity or a time capable of storing a program in a digital broadcasting storage device provided with a data storing means such as a HDD. SOLUTION: The storing means can be efficiently managed by calculating the residual usable capacity of the storing means by comparing a transmission rate of program data with the storing means and presenting to a user the calculated residual usable capacity. Also, the user can intuitively recognize the usable capacity by calculating a residual storable time for a program from the transmission rate of the program designated to be stored and the usable capacity and presenting the calculated residual storable time to the user. In addition, the whole program designated by the user can be stored by enabling the user to select video data of the program to be stored in the storing means or to set an encoding rate of the video data and audio data.

摘要： PROBLEM TO BE SOLVED: To prevent increase of source wiring resistance which is caused by increase of length of stripes, by forming conductor layers which brings an electrode conductor layer in continuity with a source leading-out wiring connected with a source region, on a semiconductor substrate in the respective stripe parts. SOLUTION: A source leading-out wiring 10 connected with the source region 8 of an MISFET has a continuity with a substrate conductor layer 1, in a linkage part, through a connecting layer 12 formed in a semiconductor substrate. The substrate conductor layer 1 has a continuity with a source electrode 13 formed on the back of the substrate conductor layer 1 as a facing surface of the semiconductor substrate main surface, and an electrode conductor layer is constituted of the source electrode 13 and the substrate conductor layer 1. The source leading-out wiring 10 and the substrate conductor layer 1 are connected, in the respective stripe parts, through conductor layers 14 formed on the semiconductor substrate between the respective cells of the respective stripe parts divided into a plurality of cells. Thereby increase of source wiring resistance which is to be caused by increase of length of the stripes can be prevented.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is not clear which should be tuned when channel numbers are overlapped when a user tries to realize direct tuning only by inputting the channel number in a receiver which receives a CATV for retransmitting a BS/CS digital broadcast service without rearranging the channel number or the like or a receiver which directly receives plural broadcasting services. SOLUTION: This tuning device is provided with a processing means for judging whether or not the channel numbers are overlapped, a processing means for presenting the overlapped channels at the same time, and a processing means for selecting one of the overlapped channels. When a channel number is inputted for direct turning, and there are plural channel numbers which are the same as the inputted value, those channel numbers are simultaneously presented to a user so that one channel number can be selected by the user. Thus, it is possible to realize direct tuning and channel-up/down tuning which is similar to the conventional manner without considering the origin of broadcasting.

摘要： PROBLEM TO BE SOLVED: To reduce the on-state resistance of a transistor which operates at a low threshold voltage. SOLUTION: In a semiconductor device, having a lateral type FET in which a source region and a drain region are formed on the main surface of a semiconductor substrate, either of the source region or the drain region which are formed on the main surface of the substrate is connected with an electrode formed on the main surface side of the substrate, and the other is connected with an electrode formed on the rear side of the substrate. In this constitution, controllability of concentration profile is satisfactory due to its being a lateral type, and operation is enabled at a low threshold voltage. Since one of a source electrode or a drain electrode is formed on the main surface of the substrate and the other is formed on the rear of the substrate, the connection region of the other electrode becomes unnecessary on the main surface of the substrate, a channel width can be enlarged with the same chip area, so that the on-state resistance of the transistor can be reduced.
