Apparatus and a method for automatically recognizing a header connected to a harvesting machine and setting operating and/or adjustment parameters of a spreader of the machine for use with the header. The apparatus includes a memory containing information representative of predetermined spreader settings for at least one header connectable to the harvesting machine, such as a grain header and a corn or maize header. A detector element is operable for automatically identifying a header connected to the machine and outputting a signal or information representative thereof, to a controller automatically operable for using that information for retrieving the stored information representative of the predetermined spreader settings for that header. Input commands and/or information, for instance, relating to crop type, and/or crop and environmental conditions, can also be inputted using either an onboard or remote input device. The controller then responsively controls a crop residue spreader connected to the machine as a function of the retrieved information and any inputted commands or information, if within predetermined permissible ranges.

The invention provides a metal wire manufacturing method and a metal wire isolating method. The method comprises the steps that 1) an anti-reflection layer is formed on a metal layer; 2) a photoresistlayer is formed on the anti-reflection layer, and an etching window is formed in the photoresist layer; and 3) a halogen-containing gas is used and an alkane-based gas is added to etch the metal layer to separate the metal layer into a number of metal lines. The alkane-based gas reacts with the halogen-containing gas to generate an auxiliary carbon halogen compound, so as to avoid the side etching of the sidewall of the metal lines and reduce the consumption rate of the photoresist layer during the etching process. According to the invention, the added alkane-based gas is used as the source of an etching aluminum by-product CClx, which can effectively reduce the etching rate of the photoresist layer; reduced line width of the metal lines and top damage, which are caused by insufficient residue of the photoresist layer, are avoided; side etching of the sidewall of the metal lines is avoided through the by-product CClx; and the overall width of the metal lines is the same as the targetwidth.
