Abstract: The disclosure relates to a method and apparatus for preventing extrusion or spiking of a metal atom from a metallization layer to other layers of a silicon wafer. In one embodiment, the method includes forming a silicon-on-ship device with a MEMS component on the substrate. The MEMS component may include one or more metal or metallic alloys.

In one embodiment, oxygen plasma and thermal oxidation methods are used to deposit spacers. In another embodiment, an oxide layer is deposited over the wafer, covering the substrate and the MEMS component. Selective etching or anisotropic etching can be used to remove the oxide layer from certain regions of the MEMS and the substrate while covering the sidewalls. An amorphous silicon layer can then be deposited to cover the MEMS device.

Abstract: A method of programming the memory cell comprises setting the memory cell to an initial state of a first gate threshold voltage, performing a processing sequence including: applying a voltage bias between the gate and the first junction region to cause electric hole to migrate towards and be retained in the trapping layer, and evaluating a read current generated in response to the voltage bias to determine whether a second gate threshold voltage is reached, wherein the second gate threshold voltage is lower than the first gate threshold voltage. The processing sequence is repeated a number of times by varying one or more time the voltage bias between the gate and the first junction region until the second gate threshold voltage is reached and the memory cell is in a program state.
