    Abstract: PROBLEM TO BE SOLVED: To provide a SOIDRAM which is high in versatility when a capacitor structure is designed, and a method for forming the structure. SOLUTION: A silicon-on-insulator(SOI) DRAM is possessed of a buried oxide layer coated with a thin crystalline silicon layer on the surface of a silicon main body substrate 10. A field oxide region is formed so as to come into contact with the buried oxide layer through the intermediary of the thin crystalline silicon surface layer. A gate oxide layer, a gate electrode 18, and a source/drain region 24 for the transfer FET of the DRAM are formed inside and on the thin crystalline silicon surface layer in an active region between field oxide regions. A groove is cut in one of the source/drain regions 24 of the transfer FETs. A doped polysilicon layer is provided conforming to the groove and patterned to serve as, at least, a part of the base electrode of a storage capacitor for the DRAM. The base electrode 32 is coated with a thin dielectric layer, and an upper electrode 36 of doped polysilicon is provided. It is preferable that a groove for a base capacitor electrode may be provided in a silicon main body penetrating through the buried oxide layer.

    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for semiconductor memory elements having wide-area tree-type capacitors for storing of data-representing charges. SOLUTION: On an Si substrate 10 a field oxide film and gate oxide film are formed. By the CVD a poly-Si film is formed, W is vacuum-evaporated and heat treated to form a low-resistance silicide film, which is then patterned to form gate electrodes WL1-WL4. Using these electrodes as a mask, P ions are implanted and diffused to form drain regions 16a, 16b and source regions 18a, 18b. A BPSG film 20 and SiN etching protection layer 22 are formed. A first insulation layer, poly-Si layers 28a, 28b and a second insulation layer are formed by the CVD. The poly-Si layer top is treated by CMP to separate into numerous independent sections. Each of the above layers is etched to form connecting holes up to the drain/source region, and poly-Si 34a, 34b are filled in the connecting holes. Tree-type memory electrodes for DRAM capacitors are formed, and dielectric counter films 36a, 36b and poly-Si facing electrodes 38 are vacuum-evaporated to complete the element.

    Abstract: PROBLEM TO BE SOLVED: To reduce power and to adjust a device to a standard by setting a system to a power cut mode and setting it to return to a regular operation mode in response to an external trigger signal under an appropriate situation. SOLUTION: When a central processing unit 10 executes a meaningless DO loop, the system starts a special service program for saving necessary data, a notice for power-cutting the central processing unit 10 is given to a power controller 20 and the central processing unit 10 becomes a power cut state for reducing power consumption. When a new event is started, a trigger controller 30 decides it or receives the external trigger signal. A starting resetting signal 16 is transmitted to the power controller 20 is response to the trigger signal, the power controller 20 is triggered by the signal and the power of the central processing unit 10 is restored. The power of the central processing unit 10 is supplied, necessary data is restored and the internal program is executed in response to the new event.

    Abstract: PURPOSE: To provide an analog synthesized musical sound inverter with the simple structure at a low cost by proportioning an output value of the converting current to a current change of the product of envelope and tone, and feeding the current, which compensates the envelop generating unit with each other. CONSTITUTION: An envelope current generating unit 30 and a tone current generating unit 40 are connected to a right side of a referential current generating unit 20 in order. A direct current drift compensating unit 70 is formed by connecting a compensating current generating unit 50 and a current amplifying unit 60 in series. In this case, total current variable (Ib1+Ib2) of the compensating current generating unit 50 and the envelope current generating unit 30 is constant. Namely, when one of current variable is increased, the other current variable is reduced. The current amplifying unit 60 following to the compensating current generating unit 50 uses an intermediate value of tone. The output signal value I0 of an analog converter 10 is in proportion to the product of tone T and envelope E, and a D/A converter, which can achieve the effect by multiplying the tone signal and the envelope signal, is formed.
