Abstract
The specification describes an integrated passive device (IPD) that is formed on a silicon substrate covered with an oxide layer. Unwanted accumulated charge at the silicon/oxide interface are rendered immobile by creating trapping centers in the silicon surface. The trapping centers are produced by a polysilicon layer interposed between the silicon substrate and the oxide layer.
