    摘要: A MEMS device having a device cavity in a substrate has a cavity etch monitor proximate to the device cavity. An overlying layer including dielectric material is formed over the substrate. A monitor scale is formed in or on the overlying layer. Access holes are etched through the overlying layer and a cavity etch process forms the device cavity and a monitor cavity. The monitor scale is located over a lateral edge of the monitor cavity. The cavity etch monitor includes the monitor scale and monitor cavity, which allows visual measurement of a lateral width of the monitor cavity; the lateral dimensions of the monitor cavity being related to lateral dimensions of the device cavity.

    摘要: Slim spacers are implemented in transistor fabrication. More particularly, wide sidewall spacers are initially formed and used to guide dopants into source/drain regions in a semiconductor substrate. The wide sidewall spacers are then removed and slim sidewall spacers are formed alongside a gate stack of the transistor. The slim spacers facilitate transferring stress from an overlying pre metal dielectric (PMD) liner to a channel of the transistor, and also facilitate reducing a resistance in the transistor by allowing silicide regions to be formed closer to the channel. This mitigates yield loss by facilitating predictable or otherwise desirable behavior of the transistor.

    摘要: A process of forming a MEMS device with a device cavity underlapping an overlying dielectric layer stack having an etchable sublayer over an etch-resistant lower portion, including: etching through at least the etchable sublayer of the overlying dielectric layer stack in an access hole to expose a lateral face of the etchable sublayer, covering exposed surfaces of the etchable sublayer by protective material, and subsequently performing a cavity etch. A cavity etch mask may cover the exposed surfaces of the etchable sublayer. Alternatively, protective sidewalls may be formed by an etchback process to cover the exposed surfaces of the etchable sublayer. Alternatively, the exposed lateral face of the etchable sublayer may be recessed by an isotropic etch, than isolated by a reflow operation which causes edges of an access hole etch mask to drop and cover the exposed lateral face of the etchable sublayer.
