Title: Method of forming electrode of semiconductor device
Inventor: SHIMADA KEIJI
IPC: H01L21/3205
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To lessen electric resistance by plating a base electrode after removing surplus electrode material excluding the base electrode after formation of the base electrode, thereby thickening the electrode as desired without reducing the light receiving area. SOLUTION: A base electrode 2 is made after formation of a resist pattern 4 in desired shape on a wafer 1. At this point of time, surplus electrode material 21 remains on the resist 4. So, surplus electrode material 21 is removed by peeling off an adhesive tape 3 after sticking, for example, an adhesive tape 3 to a wafer 1. Then, a solar cell surface electrode is completed by peeling off the resist 4 by an solvent after plating. Since the base electrode 2 is plated with resist 4 left, after the surplus electrode material 21 is removed from above the resist 4 as mentioned above, the plated electrode does not spread laterally, and surface area with desired thickness regulated by the resist pattern can be obtained.

Abstract: PURPOSE:The welding rod which comprises providing the filling powder compacted to more than the specific value of the rate of filling into a sleeve free from intermeshing seams, which is capable of considerably improving welding workability and which does not produce uneven weld zones and defects. CONSTITUTION:If a sleeve 1 free from intermeshing seams irrespective of the presence or not of weld zone 4 is used, roundness may be assured at the hot rolling and cold drawing and swaging at the production of the tube wire welding rod.
