The present invention provides a substrate treatment method to be performed after the steps of forming a desired resist pattern on a substrate and etching thereof, wherein said method comprises steps of: (I) removing the resist pattern on the substrate using a remover solution principally containing a salt derived from hydrofluoric acid and a metal-free base; (II) rinsing said substrate with a lithographic rinsing solution containing a water-soluble organic solvent and water; and (III) washing said substrate with water. According to the present invention, metallic films on the substrate are not corroded in the substrate treatment method, and the method can be performed at a low cost and with a reduced volume of labor for disposal of waste solution used for washing the substrate.

A remover solution composition for resist which comprises (a) a salt of hydrofluoric acid with a metal-free base, (b) a water-soluble organic solvent, and (c) water and optionally (d) an anticorrosive, and has a pH or 5 to 8. A method for removing resist which comprises the steps of (I) forming a resist layer on a substrate having a metal film, (II) light-exposing the resist layer through a mask pattern and subsequently developing the resist layer to form a resist pattern, and (III) dry-etching the substrate using the resist pattern as a mask and then removing the unnecessary resist and modified resist film with the remover solution composition.

Disclosed is a manufacturing management system for controlling an SMT line to manufacture printed circuit boards the manufacture of which has been designated. A source data management file created by CAD data for a printed circuit board, an inventory parts management file, a cartridge management file and an SMT line information file which includes manufacturing conditions of the SMT manufacturing equipment and equipment arrangement are registered in a database. An SMT set-up support unit creates a set-up instruction manual, which specifies set-up for manufacturing printed circuit boards on the SMT line, by referring to the various files that have been stored in the database. Further, a mounting data creating unit creates mounting data, which are for allowing the mounting machine to mount parts on printed circuit boards, using part setting position addresses of the mounting machine contained in set-up information and part mounting position coordinates contained in the source data management file.

A liquid crystal display panel 51 of N rows.times.M columns is driven by a segment driver 52 with two different voltages VS1, VS2, and by a common driver 53 with three voltages VC1, VC2, VC3. An output voltage waveform of the segment driver 52 is modulated for gradation display. The two different voltages VS1, VS2 are selected to be low voltages so as not to require high withstand voltage process in the segment driver 52, which makes it easier to integrated to a large scale in the case of realizing the segment driver 52 as a semiconductor integrated circuit.

Disclosed is a novel negative-working radiation-sensitive resist composition useful in the photolithographic patterning works of resist layers on substrate surfaces in the manufacture of semiconductor devices and capable of giving a finely patterned resist layer with high resolution and having an excellently orthogonal cross sectional profile of the line-wise patterned resist layer with an outstandingly high sensitivity to various actinic rays. The composition comprises, as the essential ingredients, (a) an alkali-soluble resin such as a cresol novolac resin, (b) a specific alkoxymethylated amino resin, e.g., methoxymethylated melamine resin, and (c) a specific triazine compound in a limited weight proportion.

A meter driving device for indicating angular positions corresponding to input values. The device includes a memory for storing previously given input values, angular directions corresponding to the input values, and coefficients representative of the grades of change in angular direction depending on the change between adjacent two input values, as parameters. Based on these parameters and the frequency of input pulse signal giving the input values, the angular direction corresponding thereto is calculated. The angular direction signal receives PWM process and then supplies to a pair of crossed exciting coils via a driver. During a predetermined time period from the turning ON and OFF of the power source, the transference of the angular direction signals to the driver is shut out by logic gates, thereby inhibiting malfunctional meter indication.
