Title: Formation of projected electrodes of semiconductor device
Inventor: IINUMA YOSHIO
IPC: H05K3/34
Filed: 1982-04-20
Abstract: PURPOSE:To obtain micro-pitched projected electrodes by employing a common electrode for plating where a plurality of metal films allowing selective etching are laminated. CONSTITUTION:A solder projected electrode 7 is formed by plating and a resist can be removed in the same way as the conventional method. In this case, however, a plating resist is a little thinner than the conventional one. A common electrode is obtained in the following steps, namely Al, Cr, Cu are sequentially laminated and Al-Cr is formed as the lower layer 4b, while Cu is formed as the upper layer 4a. When the Cu is selectively etched, an interval n between the solder plating 7 and upper layer 4a becomes small since the plating resist is thin. Thereby, the liquid does not transfer smoothly, etching is extremely delayed and the Cu layer 4a is left only at the area under the solder plating 7. Next, the lower layer 4b is etched with the Cu layer 4a used as the mask. Thereafter, the upper layer 4a is etched again and the solder layer is rounded by thermal processing. Accordingly, a solder projected electrode 8 can be completed. With such a structure, a projected electrode 8 can be completed without relation to a diameter of opening of a protection film 3. Moreover, a projected electrode can be micro-pitched in accordance with micro-miniaturization of device and a concentrated depositing stress can also be alleviated.

Title: Method for driving matrix display device
Inventor: ARAI SATOSHI
IPC: H01L29/78
Filed: 1986-03-24
Abstract: PURPOSE:To expand the life of a device by previously impressing an inversional pulse to prevent drain current from reduction due to the movement of a threshold voltage generated by impressing a selective pulse between the gate and drain of a thin film transistor (TR). CONSTITUTION:When a selective pulse is impressed to a gate line 6, a positive voltage is impressed to the gate side between the gate and drain and between the gate and source of the thin film TR 8. At that time, carriers are injected to a gate insulating film of the TR 8 from a channel. Thereby, the threshold voltage of the TR 8 is moved in a direction reducing the driving capacity of the TR 8. In order to cancel the movement of the threshold voltage, an inversional pulse having a reverse code to a selective pulse is impressed to the gate side between the gate and drain and between the gate and source prior to the impression of the selective pulse. Consequently, all carriers injected into the gate insulating film are discharged to the channel. Thereby, the threshold voltage of the TR 8 is varied within a minute time, but in a long time, there is no variation in the threshold voltage.

Title: Field effect transistor
Inventor: TOUNO HIROSHIGE
IPC: H01L29/43
Filed: 1993-03-24
Abstract: PURPOSE:To increase only the intrinsic gate capacitance and decrease the input impedance of an MESFET, without exerting influence upon the characteristics of the MESFET. CONSTITUTION:A first electrode part 13a is formed on a channel region 2, so as to leave 0.3mum from the drain region 4a side. A second electrode 13b is formed on a source electrode 4b. Thereby only the intrinsic gate capacitance can be increased without changing the mutual conductance and the current value. Hence the input impedance of an MOSFET can be decreased, and the constitution of an input matching circuit in the case of MMIC configuration can be simplified. Not only the generation of mismatching can be evaded, but also the internal loss of input matching circuit itself and the loss caused by reflection of electric signal can be reduced.

Abstract: PURPOSE:To eliminate close operations even in the case of a fine drawing and to facilitate the operation of a coordinate input device by producing a coordinate ratio and the relative coordinate value. CONSTITUTION:A coordinate input device and an input pointer (pen) 4 are connected to a main body 3 with a cable and the subject device receives the magnetic field generated by the pen 4 via the coil of the main body 3 to read the coordinates.

Then a coordinate ratio and the original point coordinate value are set to magnify/reduce a distance on a planar plate based on the pointing signal which controls the coordinate input device. The original point coordinate value is added to the product obtained between the coordinate ratio and the absolute coordinate value showing the position of the pen 4 for production of the relative coordinate value. As a result, a part of a drawing can be displayed on the entire input screen with an optional point defined as an original point on the display screen of a display device. Thus a close drawing can be easily inputted on a screen, as well.

Filed: 1982-04-20
Abstract: PURPOSE:To obtain a modulator of small-scale circuit constitution by detecting the polarity of a difference frequency between a reference frequency and the mean frequency of a frequency-modulated wave, and performing frequency synchronization. CONSTITUTION:A frequency difference polarity detector 7 detects whether the difference of the frequency of a voltage-controlled oscillator 6 from the frequency of a reference frequency oscillator 1 is positive or negative by making a comparison between both. Binary pulses from this detector 7 are sent to a up/ down counter 8 to output binary pulses based upon whether the shift in the mean frequency of the oscillator 6 from the reference frequency and they are converted into an analog value by a D/A converter 9. The output of this converter 9 is converted almost into a direct current by a loop filter 4' to obtain a control voltage, which is fed back to the oscillator 6 to synchronize the mean frequency with the reference frequency of the oscillator 1. Thus, the need for a frequency divided of large-scale circuit constitution is eliminated to reduce the circuit constitution.
