A method of forming at least one Micro-Electro-Mechanical System (MEMS) includes forming a lower sacrificial material used to form a lower cavity. The method further includes forming a cavity via connecting the lower cavity to an upper cavity. The cavity via is formed with a top view profile of rounded or chamfered edges. The method further includes forming an upper sacrificial material within and above the cavity via, which has a resultant surface based on the profile of the cavity via. The upper cavity is formed with a lid that is devoid of structures that would interfere with a MEMS beam, including: depositing a lid material on the resultant surface of the upper sacrificial material; and venting the upper sacrificial material to form the upper cavity such the lid material forms the lid which conforms with the resultant surface of the upper sacrificial material.

A resistor with heat sink is provided. The heat sink includes a conductive path having metal or other thermal conductor having a high thermal conductivity. To avoid shorting the electrical resistor to ground with the thermal conductor, a thin layer of high thermal conductivity electrical insulator is interposed between the thermal conductor and the body of the resistor. Accordingly, a resistor can carry large amounts of current because the high conductivity thermal conductor will conduct heat away from the resistor to a heat sink. Various configurations of thermal conductors and heat sinks are provided offering good thermal conductive properties in addition to reduced parasitic capacitances and other parasitic electrical effects, which would reduce the high frequency response of the electrical resistor.

A method of forming at least one Micro-Electro-Mechanical System (MEMS) cavity includes forming a first sacrificial cavity layer over a lower wiring layer. The method further includes forming a layer. The method further includes forming a second sacrificial cavity layer over the first sacrificial layer and in contact with the layer. The method further includes forming a lid on the second sacrificial cavity layer. The method further includes forming at least one vent hole in the lid, exposing a portion of the second sacrificial cavity layer. The method further includes venting or stripping the second sacrificial cavity layer such that a top surface of the second sacrificial cavity layer is no longer touching a bottom surface of the lid, before venting or stripping the first sacrificial cavity layer thereby forming a first cavity and second cavity, respectively.
