    摘要: Jogs are sometimes needed in lines that are used as wires in integrated circuits. In the prior art, these jogs are introduced by inserting a diagonal segment at the desired location. This type of shape is expensive to generate when electron beam writing is used. In the present invention the problem is solved by forming the jog through a simple lateral sliding of two halves of the line relative to one another. The resulting line pattern has both sharp corners and a central constriction but when it is transferred to photoresist, using standard photolithographic techniques, both the sharp corners and the constriction are no longer present, provided no OPC was applied to that section of the line. The motivation for this is the much lower cost of E-beam drawing for the structure of the present invention relative to structures of the prior art.

    摘要: A structure includes a metal pad over a semiconductor substrate, a passivation layer having a portion over the metal pad, and a first polyimide layer over the passivation layer, wherein the first polyimide layer has a first thickness and a first Young's modulus. A post-passivation interconnect (PPI) includes a first portion over the first polyimide layer, and a second portion extending into the passivation layer and the first polyimide layer. The PPI is electrically coupled to the metal pad. A second polyimide layer is over the PPI. The second polyimide layer has a second thickness and a second Young's modulus. At least one of a thickness ratio and a Young's modulus ratio is greater than 1.0, wherein the thickness ratio is the ratio of the first thickness to the second thickness, and the Young's modulus ratio is the ratio of the second Young's modulus to the first Young's modulus.
