Abstract: Interconnections are formed over an interlayer insulating film which covers MISFETQ1 formed on the principal surface of a semiconductor substrate, while dummy interconnections are disposed in a region spaced from such interconnections. Dummy interconnections are disposed also in a scribing area. Dummy interconnections are not formed at the peripheries of a bonding pad and a marker. In addition, a gate electrode of a MISFET and a dummy gate interconnection formed of the same layer are disposed. Furthermore, dummy regions are disposed in a shallow trench element-isolation region. After such dummy members are disposed, an insulating film is planarized by the CMP method.

Abstract: A liquid chemical treatment apparatus includes a coating apparatus for applying a coating liquid such as resist onto the surface of a substantially planar substrate such as a glass substrate. The coating apparatus includes a nozzle with an elongate injection outlet such as a slit with a width substantially the same as that of the substrate, and a liquid circulating passage connected to the nozzle for supplying the coating liquid to the nozzle. Mechanisms are provided with the circulating passage and the nozzle to remove air from the liquid, and to maintain the circulating liquid at a substantially constant temperature and a substantially constant flow rate.

Abstract: In a method of removing a coating from an edge of a substrate a solvent reservoir is filled with a solvent to dissolve and remove a photoresist film, the solvent includes one of dipropylene glycol monoalkyl ether, a mixture of this ether and an easily volatile organic solvent (boiling point of 75-130.degree. C., vapor pressure of 5-75 mmHg at 20.degree. C.), and an alkaline aqueous solution, an edge of a substrate W is horizontally inserted in the reservoir, and thereafter, the edge of the substrate W is immersed in the solvent for a period of time, so as to dissolve and remove a coating such as photoresist from the edge of the substrate. The solvent may be filled into the solvent reservoir either before or after the edge of the substrate is inserted therein, and the method may further involve aspirating the solvent from the reservoir after the substrate edge has been inserted therein.

Abstract: The invention proposes an improved method for the pre-treatment of a photoresist layer formed on a substrate surface prior to pattern-wise exposure of the photoresist layer to actinic rays, in which extraneous portions of the resist layer formed by overspreading of the photoresist solution as in the marginal zone of the patterning area and on the peripheral and back surfaces of the substrate, by dissolving away with a cleaning solution. In contrast to the conventional cleaning solutions consisting entirely or mainly of an organic solvent capable of dissolving the photoresist composition, the cleaning solution used in the inventive method is an aqueous alkaline solution containing a water-soluble alkaline compound dissolved in an aqueous medium consisting of water and a limited amount of a water-miscible organic solvent such as monohydric alcohols, alkyleneglycol monoalkyl ethers and aprotic solvents. The cleaning solution may optionally contain an anti-corrosion agent.

Abstract: A rotating cup type liquid supply device comprises an inner cup 3, a vacuum chuck 5 disposed in the center of a bottom surface of the inner cup 3 for holding thereon a planar material W to be treated, and a tray 7 fixed onto the bottom surface of the inner cup 3 for substantially surrounding the planar material W held by the vacuum chuck 5. The tray is of a substantially rectangular shape in plan view and includes an tapered wall portion 9 turned inwardly along a circumferential wall portion thereof for defining an upper opening 8 of the tray 7. The tray 7 further includes a plurality of drain guiding conduits 10 each extending at a predetermined angle outwardly from an outer peripheral portion thereof. Also, the tray can be provided thereon with the cover having an opening slightly larger than the planar material W.

Abstract: This reference voltage generator device detects a voltage corresponding to an energy gap of a semiconductor, or a voltage of a value close thereto, or a voltage based on an energy level of a semiconductor, and generates the detected voltage as a reference voltage. The reference voltage is generated by detecting a difference of threshold voltages of first and second insulated gate field-effect transistors (IGFETs). Gate electrodes of the first and second IGFETs are formed on gate insulating films which are formed on different surface areas of an identical semiconductor substrate under substantially the same conditions. The gate electrodes of the first and second IGFETs are respectively made of two semiconductors which are selected from among a semiconductor of a first conductivity type, a semiconductor of a second conductivity type and an intrinsic semiconductor made of an identical semiconductor material, and which have Fermi energy levels of values different from each other.

Abstract: With the reduction in the size of semiconductor integrated circuit devices, there have been increases in the resistance at the contact portions of metal interconnections and in the incidence of contact failure.
