摘要： Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.

摘要： Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.

摘要： Provided are a Cu core ball and a cu core column, which achieve dropping strength and strength against heat cycle. The Cu core ball (1) contains a Cu ball (2) made of Cu or a Cu alloy and a solder layer (3) which is made of a solder alloy composed of Sn and Cu and covers the Cu ball (2). The solder layer (3) contains not less than 0.1 % through not more than 3.0 % of Cu and the remainder is composed of Sn and impurities.
