Disclosed is a method for stripping a photoresist comprising: (I) providing a photoresist pattern on a substrate where the substrate has at least a copper (Cu) wiring and a low-dielectric layer thereon, and selectively etching the low-dielectric layer by using the photoresist pattern as a mask; (II) contacting the substrate after the step (I), with ozone water and/or aqueous hydrogen peroxide; and (III) contacting the substrate after the step (II), with a photoresist stripping solution that contains at least a quaternary ammonium hydroxide. The present invention provides a method for stripping a photoresist that enables to strip effectively photoresist films and etching residues after etching step even in a process not including an O₂ plasma ashing treatment in micropatterning of a substrate having at least Cu wiring and a low-dielectric layer thereon, as in a dual damascene forming process, and, in addition, the method of the invention does not have any negative influence on the dielectric constant of the low-dielectric layer, and ensures an excellent anti-corrosivity.

A wide pick-up for a baler includes a crop feed rotor and auger arrangement located at an elevated position rearward of a tined pick-up reel arrangement. Positioned for receiving crop delivered by the reel arrangement, and extending beneath the crop feed rotor and auger arrangement is a crop guide plate arrangement including a central movable crop guide plate portion mounted to be moved vertically between a raised feed position, wherein it is relatively close to a circular path traced by the outer peripheries of the crop feed rotor and the converging augers, and a lowered, crop unplugging position, wherein it is spaced to create a gap between the crop guide plate portion and the crop feed rotor and auger arrangement. Right and left, primary crop stripper plates are respectively mounted to right and left front end regions of the moveable crop feed plate portion, with the primary stripper plates each having an edge located close to the associated auger for preventing crop from being wrapped about the augers when the movable crop guide plate portion is in its normal raised operating position. Right and left secondary crop stripper plates are respectively mounted to right and left fixed walls extending upwardly about the augers from right and left fixed guide plate portions, these secondary stripper plates remaining in place to strip crop from the augers when the central movable crop guide plate portion is lowered.

The invention relates to a detaching apparatus and a detaching method. A plurality of attracting units (51-54) are configured in a detaching performing direction, namely a +Y direction. A first attracting unit (51) at a most upstream side attracts an end of a retained substrate (SB) for lifting. Furthermore through making a detaching roller (340) abut against the substrate (SB) and move in the detaching performing direction, thereby controlling detaching. When the detaching roller (340) passes through the position right below a second attracting unit (52) to a fourth attracting unit (54), the substrate after detaching is captured and lifted through making each attracting unit (52-54) descending, thereby making the attracting units which perform the function of detaching from the body successively move to the downstream side.
