Title: Probe for test of semiconductor integrated circuit device
Inventor: FUJIMOTO HIDETOSHI
IPC: H01L21/66
Filed: 1990-04-03
Abstract: PURPOSE:To enable characteristic test to be performed regardless of a narrow electrode which is approximately 50mum by embedding a plurality of probes consisting of a conductive material with a specific diameter length into an insulated support substrate. CONSTITUTION:A diameter of a probe 1 consisting of a conductive material such as a metal (tungsten, palladium, etc.) is 50mum or less and is buried at an insulated support substrate 2 made of, for example, resin. These probes 1 are connected to measuring device by a lead 3. A thickness (d) of the insulated support substrate 2 should normally be approximately 4-5mm since it needs to withstand the pressure which is applied to a probe for test for allowing the probe and an electrode to contact fully. Also, assuming that this insulated support substrate 2 is a transparent resin, it is convenient since it is possible to inspect an alignment between the probe and the electrode visually from above when performing characteristic test. On principles, if the diameter of the probe is 50mum or less, measurement can be made without mutual contact to perform characteristic test of a semiconductor integrated circuit device where an interval between the electrodes is 50mum without any contact. However, it is more desirable that the diameter is 20-30mum.

Consequently, the brightness display ability that a display device has originally can be used sufficiently to display the brightness image data.

Inventor: FURUHATA SHOICHI
IPC: H02M7/537
Filed: 1989-04-07
Abstract: PURPOSE:To integrate a circuit into one chip by providing a resistor for detecting the overcurrent of a main circuit in series with an insulating gate element IGBT, and suppressing the gate control voltage of the IGBT by detecting the voltages at both ends of the resistor. CONSTITUTION:The resistor 11 is inserted to the emitter E of the IGBT 1, and the voltages at both ends of the resistor 11 are applied on the base B and the emitter E of an auxiliary transistor 5. When a current over a rated current on the IGBT 1 and the voltage higher than that between the base and the emitter when the auxiliary transistor 5 is turned on is generated, the transistor 5 is turned on, and the gate voltage eg of the IGBT 1 is decreased nearly to the Zener voltage of a Zener diode 6, which limits the overcurrent by the IGBT 1 itself. In such a way, since a large magnitude of current flows on the resistor 11, its resistance value is remarkably reduced, which facilitates the formation of the circuit into an integrated circuit.

Title: Manufacture of dry type lithography pattern
Inventor: GOTOU HIDEKAZU
IPC: G03F7/20
Filed: 1983-05-20
Abstract: PURPOSE:To simplify a process and improve the yield of the manufacture of a device by controlling the temperature of a substrate where a resist film of low polymerization degree is formed in two stages, and performing exposure to the resist film and removing the resist. CONSTITUTION:The substrate 1 where the resist film 2 of low polymerization degree is formed is arranged in an exposing device, and held at low temperature (e.g. -100 deg.C) where the vapor pressure of the resist of low polymerization degree is essencially low. The resist film 2 is exposed in a said state to form an exposed resist pattern 3 have high polymerization degree. When the temperature of the substrate is raised to relatively high temperature (e.g. >=20 deg.C), only the exposed resist pattern 3 of high polymerization degree is left on the substrate, and the resist 2 of low polymerization degree which is not exposed is separated away to form a resist pattern. Thus, the substrate temperature is only raised from the low temperature to the high temperature to form the exposed resist pattern, so operation is carried out sequentially in the exposure device without moving the substrate from under a vacuum into the air like a wet treatment. Consequently, the manufacturing time is shortened and the yield of the manufacture of a highly integrated device is improved.

Abstract: PURPOSE:To reduce the space of a device and simplify connections and handle X-axis and Y-axis electrodes simultaneously by superimposing leading-out electrodes of X-axis and Y-axis conductive piece groups in two, namely, upper and lower stages to reduce the width of leading-out electrodes to half. CONSTITUTION:Leading-out electrodes 4 of X-axis conductive piece groups are constituted as the upper stage, and leading-out electrodes 5 of Y-axis conductive piece groups are constituted as the lower stage. An insulating sheet 6 or the like is arranged between both leading-out electrodes in the part, where one of them is put on the other, to prevent the short-circuit between them. Leading-out electrodes are superimposed in two, upper and lower stages in this manner to reduce the width of leading-out electrodes to half, and as the result, the width of connection cords is reduced to half to reduce the space of the device. Since a receptacle with two, upper and lower stages as a set can be used in case of cord connection, connection and disconnection of cords are simplified, and X-axis and Y-axis electrodes can be handled simultaneously.

Abstract: PURPOSE:To enable stability when controlling load to be improved by adding a prediction load fluctuation signal to a total load command signal and by eliminating load fluctuation due to frequency fluctuation which appears in a total load deviation signal. CONSTITUTION:A system frequency is fed to a function generator 20 through a frequency detector 3.
