In an electronic apparatus having a membrane switch and a touch panel switch at its entirety section, the touch panel switch is elastic and is laid over the membrane switch. The two-layered structure provides users with two operations: a &ldquo;finger-sliding&rdquo; operation and a &ldquo;finger-depressing operation.&rdquo; When a user slides a finger on the surface of the touch panel switch, the sliding force activates the touch panel switch. The &ldquo;finger-sliding&rdquo; is used for selecting a desired item. On the other hand, when the user presses down on the surface of the touch panel switch, the depression force through the touch panel switch activates the underlying membrane switch. The &ldquo;finger-depressing&rdquo; is used for numeric or symbolic information entry. It is thus possible to realize an electronic apparatus offering an excellent compromise between ease of operation and a wide display section.

Electronic apparatus having plural entry switches

A touch type input device is used for various forms of control. A primary side line is connected to a power source, and a secondary side circuit ground through a power transformer are connected by an impedance element. Flat electrodes to be touched by a finger are formed on one side of an insulating base material, and are connected to a ground current detection circuit through a high resistor and a low pass filter. A control circuit for converting the output of the ground current detection circuit into a control signal for an electronic appliance, and a display unit are provided. Therefore, an input device having plural touch switches disposed on a base material in a free shape and layout can be obtained.

The semiconductor masking device of the invention includes a first semiconductor mask for forming an interconnection on a semiconductor substrate and a second semiconductor mask for forming a resist pattern on an insulating film. The first semiconductor mask has three masking areas and the second semiconductor mask has two masking areas. Masking area intervals, that is, the distances between the three masking areas of the first semiconductor mask and the two masking areas of the second semiconductor mask, are all equal to one another.

A signal transmitter and receiver (or a combination thereof) incorporated for example in audio and video apparatus such as a TV and a video-deck, comprises a synchronizing signal separator separating a synchronizing signal from video-signal, a monostable circuit of which period recovering its stable state, or unstable period, after an input of triggering signal, is longer than the period of synchronizing signal separated by the synchronizing signal separator, and a dc-power supply on-off controller controlling the on-off of dc-power supply according to the output of the monostable circuit. The dc-power supply on-off controller limits the supply of dc-power to a minimal number of circuits except during signal processing.

An ion implantation stopper is formed on a gate electrode extending on a substrate. When ions are implanted into the substrate to form an LDD layer or source and drain regions in the substrate, the stopper functions to prevent the gate electrode from being exposed to ion implantation. The prevention of the exposure of the gate electrode to the ion implantation ensures the prevention of channeling in the gate electrode. The invention includes forming a first protective film on the gate of an NMOS, implanting to form LDD region for the NMOS, implanting to form source and drain regions of a PMOS, forming a second protective film on the gate of the NMOS, implanting to form source and drain regions of the NMOS, the first and second protective films prevent the gate electrode of the NMOS from being exposed to ion implantation during the respective implanting steps so that channeling is prevented from occurring in the gate electrode of the NMOS.
