Methods and apparatus are provided for preparing sensing fingers for use
in a highly integrated accelerometer. The method includes steps for
forming a tungsten/tungsten silicide coating on a silicon finger. The
tungsten/tungsten silicide coating adds mass to the silicon finger. The
method includes steps of forming silicon fingers from layers of silicon,
oxides, and capping material. The silicon fingers are then exposed to
tungsten containing gases under conditions to promote the formation of a
tungsten silicide seed layer on the exposed silicon surfaces. The
tungsten layer is then grown to a desired thickness through a growth
step. The coated silicon fingers display improved resistance to stiction
as compared to uncoated silicon fingers.
