发明名称 METHOD FOR FORMING STUDS USED FOR SELF-ALIGNMENT OF SOLDER BUMPS
摘要 A method and a combination of studs, silicon chips, and solder bumps configured to restrict motion of a plurality of silicon chips. The combination includes: a plurality of studs, a plurality of silicon chips, a plurality of target solder bumps, where the plurality of solder bumps are melted between the plurality of silicon chips, where lateral positions of the plurality of studs are in accord with a pitch of the plurality of target solder bumps by using the pitch as a reference, where (i) lateral positions and lateral widths of studs of the plurality of studs located at a first silicon chip of the plurality of silicon chips and (ii) lateral positions and lateral widths of studs of the plurality of studs located at a second silicon chip of the plurality of silicon chips are restricted such that relative lateral motion on the respective silicon chips is restricted.
