First through holes of a relatively small diameter and second through holes of a relatively great diameter are formed in proper shapes by separate processes, respectively, in a first layer insulating film. The second through holes are tapered toward a layer underlying the first layer insulating film. First, the first through holes are formed in the first layer insulating film, the first through holes are filled up with plug electrodes, and the second through holes are formed in the first layer insulating film. When filling up the first and the second through holes formed in the first layer insulating film with plug electrodes, a first conductive film deposited over the first layer insulating film is etched back to fill up the first through holes with the plug electrodes, and then etch back residues remaining on the side walls of the second through holes are removed.

A musical apparatus which outputs music under the control of various musical control instructions where the desired musical control instructions are reliably determined by the movement of an object in an operation space, and where the musical control instructions are varied by changing the state of motion of the object in space.The musical apparatus performs musical control instructions whose contents are based on the state of motion of an object in motion within a specified operation space. The musical apparatus may have at least one light source which shines light into said operation space, at least one light sensor which receives light which has been reflected by an object in the space so that it has at least two light paths which reach from the light source to the light sensor via the object, so that a detection values is output according to the quantity of light received via a respective one of the light paths, and a musical controller which outputs music and controls a musical function when the correlation between the current values of the detection values of the various paths satisfies a specified relationship.

In an electro-mechanical energy conversion device which is disclosed, green sheets on which whole surface electrodes for grounding have been printed and green sheets on which 2-divided electrodes have been printed are laminated. The green sheets having the 0.degree. phase and 90.degree. phase on which the 2-divided electrodes have been printed are laminated through the printed sheet on which the whole surface electrode for grounding. After the laminate body was sintered and integrated, it is polarized in a manner such that the polarizing directions in the thickness direction of each layer are opposite between the two divided electrodes which form one pair by using the whole surface electrodes for grounding and the 2-divided electrodes which were printed, thereby constructing the conversion device for the laminated type vibration driven motor.

A method is provided for manufacturing a semiconductor integrated circuit device which includes a capacitor element having a first electrode, a second electrode, and a dielectric film formed between said first electrode and said second electrode. In particular, the method includes the step of forming at least one of the first electrode and second electrode with a polycrystalline silicon film which is deposited over a semiconductor substrate by a CVD method and which is doped with an impurity during said deposition to decrease the resistance of the polycrystalline silicon film. The capacitor element formed by this method is particularly useful for memory cells of static random access memory devices.

Herein disclosed is a semiconductor integrated circuit device comprising a SRAM having its memory cell composed of transfer MISFETs to be controlled through word lines and drive MISFETs. The gate electrodes of the drive MISFETs and the gate electrodes of the transfer MISFETs of the memory cell, and the word lines are individually formed of different conductive layers. The drive MISFETs and the transfer MISFETs are individually arranged to cross each other in the gate length direction. The word lines are extended in the gate length direction of the gate electrodes of the drive MISFETs and caused to cross the gate electrodes of the drive MISFETs partially.The two transfer MISFETs of the memory cell have their individual gate electrodes connected with two respective word lines spaced from each other and extended in an identical direction. The region defined by the two word lines is arranged therein with the two drive MISFETs and the source lines.The source line is formed of a conductive layer identical to that of the word line. The individual data lines of the complementary data line are formed of an identical conductive layer which is different from that of the word line and the source line. The identical conductive layer between the word line and source line and the complementary data line is formed with two word lines: a main word line extended in the first direction identical to that of the word line and source line and used by adopting the divided word line system: and a sub-word line used by adopting the double word line system.

An improved buffer circuit arrangement is provided which is particularly useful for semiconductor integrated circuit semiconductor memories and microprocessors. The buffer circuit is capable of switching large loads in various types of LSIs, and features a low noise and high speed circuit operation. This is accomplished by a parallel connection of output transistors in an output buffer circuit, and by differentiating the starting time of operation between the output transistors connected in parallel without using a delay circuit. For example, differentiating the starting times can be achieved by either providing the transistors with different characteristics from one another or the driving circuits with different characteristics from one another. Another aspect of the circuit is the provision of a two-level preset arrangement which presets the output node of the circuit to predetermined values before the input signals are applied.
