POWER DEVICE WITH SELF-ALIGNED SILICIDE CONTACT

摘要

An improved power device with a self-aligned suicide and a method for fabricating the device are disclosed. An example power device is a vertical power device that includes contacts formed on gate and body contact regions by an at least substantially self-aligned silicidation (e.g., salicide) process. The example device may also include one or more sidewall spacers that are each at least substantially aligned between edges of the gate region and the body contact region. The body contact region may also be implanted into the device in at least substantial self-alignment to the sidewall spacer. The method may also include an at least substantially self-aligned silicon etch.
