Abstract: A method of printing transferable components includes pressing a stamp (10) including at least one transferable semiconductor component (20) thereon on a target substrate (30) such that the at least one transferable component and a surface of the target substrate contact opposite surfaces of a conductive eutectic layer (31). During pressing of the stamp on the target substrate, the at least one transferable component is exposed to electromagnetic radiation (4) that is directed through the transfer stamp to reflow the eutectic layer. The stamp is then separated from the target substrate to delaminate the at least one transferable component from the stamp and print the at least one transferable component onto the surface of the target substrate. Related systems and methods are also discussed.

Abstract: 従来の高速・大電流の半導体チップでは、チップの片面に全ての電気的接続端子を配置していた。このため、安定した電源電流を供給したり、電源から信号系へ混入する雑音を低くするため、多くの端子を電源流入端子と電源流出端子に割いていた。この結果、前記半導体チップを搭載した半導体デバイスの端子数の増大、実装面積の増大といった課題があった。 半導体チップの両面に電源系と信号系の電気的接続端子を振り分けて配置する。大電流が流れる流路の許容電流値を大きくする構成により、少ない端子数でも安定な電源供給が可能、信号系への雑音混入を低減、ピン数の低減による実装面積の低減、放熱効果の増大などが可能となる。また、この半導体チップを搭載した半導体モジュールにより、大電流が流れる高速動作でも安定した特性を実現できる。
Abstract translation: 在传统的高速大电流半导体芯片中,所有电连接端子设置在芯片的一个表面上。 为此,为了提供稳定的电源电流并降低信号系统中混合的噪声,已经为电源电流流入端子和电源电流流出端子分配了大量端子。 因此,存在安装有所述半导体芯片的半导体器件的端子数量增加以及安装面积增加的问题。 电连接端子分为电源系统的端子和信号系统的端子,并且设置在半导体芯片的两侧。 增加大电流流过的流路的允许电流值的结构例如即使使用少量端子也能够提供稳定的电力,可以降低混合在信号系统中的噪声,降低安装面积 通过减少引脚数量,并增加散热效果。 通过安装该半导体芯片的半导体模块,即使在大电流的高速运转中,也可获得稳定的特性。

Abstract: A bonding wedge particularly suitable for making wire off-die interconnects includes an aperture (aperture) opening onto a notch (notch) or pocket adjacent to the rear of a foot (foot). The foot includes a heel portion (heel) and a toe portion (toe). When the bonding wedge is in use, a wire is fed from feedstock through the aperture and the notch or pocket, and passes beneath the foot and extends beyond the toe. The toe is configured to mitigate upward displacement of the free end (free end) of the wire during the bonding process.
