摘要:
A semiconductor device has a die (10) overlying and electrically connected to a support structure (11), such as a substrate or a lead frame, via a plurality of interconnects. Aggressor interconnects (32, 38) are noise sources to victim interconnects (29, 59) carrying sensitive signals. An arrangement of shield interconnects (51-58) surround the victim interconnect (29, 59) in a cage-like structure to significantly block noise from the aggressor interconnect. In one form the shield interconnects are ground or power supply and the victim interconnect may be, for example, a clock signal or an RF signal. The number of shield interconnects and the number of protected victim interconnects varies depending upon design requirements. Either wire bonding or other interconnect technology (e.g. bump) is applicable.

In a semiconductor device, a bus bar (4a) is provided with a projection (9a). Based on a positional relationship between the projection and a metal wire (13a) subjected to the lateral deflection upon resin filling, the metal wire lateral deflection amount is managed. The projection may be provided on a suspension pin or at another portion of a lead frame. A cutout may be provided instead of the projection.
摘要:
@ A bond wire connection between two semiconductor devices alleviates the problem of inductive loading at high frequencies by providing a capacitive effect which compensates for inductive reactance. The capacitive effect is provided by utilizing multiple parallel layers of bond wires at a common electrical connection point. As more layers are added the net impedance can be controlled so as to match the impedance driving the downstream semiconductor.
