Before the second step is performed, a step of performing recess etching may be further performed on the regions of the substrate exposed through the opening patterns while the substrate is masked with the fine electrode-forming masking member.
The method for forming the fine electrodes described above is preferably applied to the formation of gate electrodes for field effect transistors. In this case, the substrate may be a semiconductor substrate, and the fine electrode may be a gate electrode used in a field, effect transistor.
Furthermore, the present invention is applied to a field effect transistor using the gate electrode formed by the method for forming the fine electrodes described above.
Other features and advantages of the present invention will become apparent from the following description of embodiments of the invention which refers to the accompanying drawings. Battery clamps for securing electrical leads to the terminal posts of motor vehicle batteries generally have securing means comprising an "U" shaped body having a bolt passing through the legs and secured by a nut on the threaded end of the bolt. This system suffers from the disadvantage of requiring a spanner of the correct size to connect or disconnect the clamp and further, the bolt being of a corrosive material, tends to corrode, resulting in difficulty in removal and possible damage to the clamps or terminal post. Although other types of clamp have been used, e.g. a spring release clamp, these suffer from one or other of these disadvantages, resulting in delays when connecting or disconnecting batteries in service. The present invention relates to a suction pipe for suction dredgers with mechanical feeder and cutter means adapted to handle the material dredged. Suction dredgers of this type are adopted in large numbers to condition the beds of lakes and stream courses. It is already known in the art to associate mechanical feeder and cutter means with the suction pipes for dredging purposes.
It is likewise known in the art that these feeder means as such impose a load torque on the suction pipe which the pipe would pass on to the bottom of the dredge vessel so that suction pipe and vessel bottom must be of greater size than otherwise required.
On the other hand there are deadcycle times involved in the process for sucking material from below the water surface for suction dredgers and other hydraulic conveyors whenever larger size rocks are caught in front of the suction pipe, and in general wherever rock and clay material is to be handled.

 Before the second tone is performed, a step of perform recess etching may be far performed on the regions of the substrate expose through the opening patterns while the substrate is masked with the fine electrode - forming masking extremity. 
 The method for forming the fine electrode described above is preferably applied to the constitution of gate electrodes for battlefield effect transistors. In this case, the substrate may be a semiconductor substrate, and the fine electrode may be a gate electrode use in a field, effect transistor. 
 Furthermore, the present invention is applied to a field effect transistor use the gate electrode shape by the method for forming the fine electrodes described above. 
 Other feature of speech and advantage of the present invention will become apparent from the following description of embodiments of the invention which refers to the play along drawings. Battery clamps for fasten electric leads to the terminal posts of motor fomite batteries generally have securing means comprising an " U " shape body having a bolt passing through the leg and procure by a nut on the threaded end of the bolt. This system suffers from the disadvantage of requiring a wrench of the correct size to get in touch or disconnect the clamp and further, the dash being of a corrosive fabric, tends to corrode, resulting in difficulty in removal and possible damage to the clamp or terminal post. Although other types of clamp have been use, e.g. a spring passing clamp, these suffer from one or early of these disadvantages, resulting in delays when plug in or disconnecting batteries in service. The present invention relates to a suction pipe for sucking dredgers with mechanical feeder and stonecutter means adapted to handle the material dredged. Suction dredgers of this character are adopted in large numbers to condition the beds of lakes and stream courses. It is already know in the artwork to consociate mechanical feeder and cutter means with the suction pipes for dredge purposes. 
 It is likewise known in the artwork that these feeder mean as such impose a load torque on the sucking pipe which the pipe would pass on to the bottom of the dredge vessel so that suction pipe and vessel bottom must be of great size than otherwise required. 
 On the other hand there are deadcycle times necessitate in the process for sucking fabric from below the urine surface for suction dredgers and other hydraulic conveyors whenever larger size rock are caught in front of the suction pipe, and in general wherever rock and clay fabric is to be handled.
