Abstract: A topographical feature is formed proximate to a conductive bond pad that is used to couple a solder bump to a semiconductor die. The topographical feature is separated from the conductive bond pad by a gap. In one embodiment, the topographical feature is formed at a location that is slightly beyond the perimeter of the solder bump, wherein an edge of the bump is aligned vertically to coincide with the gap separating the conductive bond pad from the topographical feature. The topographical feature provides thickness enhancement of a non-conductive layer disposed over the semiconductor die and the conductive bond pad and stress buffering.

Abstract: Disclosed are embodiments of a structure having a metal layer with top surface and sidewall passivation and a method of forming the structure. In one embodiment, a metal layer is electroplated onto a portion of a seed layer at the bottom of a trench. Then, the sidewalls of the metal layer are exposed and, for passivation, a second metal layer is electroplated onto the top surface and sidewalls of the metal layer. In another embodiment, a trench is formed in a dielectric layer. A seed layer is formed over the dielectric layer, lining the trench. A metal layer is electroplated onto the portion of the seed layer within the trench and a second metal layer is electroplated onto the top surface of the metal layer. Thus, in this case, passivation of the top surface and sidewalls of the metal layer is provided by the second metal layer and the dielectric layer, respectively.

Abstract: The present invention provides a micro-electro-mechanical-system (MEMS) temperature sensor that employs a suspended spiral comprising a material with a positive coefficient of thermal expansion. The thermal expansion of the suspended spiral is guided to by a set of guideposts to provide a linear movement of the free end of the suspended spiral, which is converted to an electrical signal by a set of conductive rotor azimuthal fins that are interdigitated with a set of conductive stator azimuthal fins by measuring the amount of capacitive coupling therebetween. Real time temperature may thus be measured through the in-situ measurement of the capacitive coupling. Optionally, the MEMS temperature sensor may have a ratchet and a pawl to enable ex-situ measurement.
