Title: A Method for Forming Solder Ball
Inventor: SANO YASUSHI
IPC: H01L23/12
Filed: 2000-09-05
Abstract: PURPOSE: To be able to form taller solder balls (bumps) by screen printing. CONSTITUTION: A first solder layer is printed in a first printing step S10. After drying at a drying step S20, a second solder layer is printed on the first solder layer. Lastly, a reflow treatment is performed at a reflow treatment step S40, the first and the second solder layers are melted and solder balls (bumps) are formed by cousing solder to soldify into sphere shape. The volume of the solder is increased because the solder is printed by laminating, therefore tall solder balls (bumps) are formed.
