Abstract: A method is described for extracting the spatial distribution of charge stored in a charge-trapping layer of a semiconductor device. The method comprises the steps of performing a first charge-pumping measurement on a device under test using a variation of the upper level of the pulse and performing a second charge-pumping measurement on this device using a variation of the lower level of the pulse. The data obtained is combined for extracting the spatial distribution. This is done by establishing a relation between a charge pumping current Icp and a calculated channel length Lcalc of the semiconductor device by reconstructing spatial charge distribution estimates from the charge pumping curves for multiple values of the charge pumping current Icp.

Abstract: Manufacturing a semiconductor device involves forming (200) a sacrificial layer where a micro cavity is to be located, forming (210) a metal layer of thickness greater than 1 micron over the sacrificial layer, forming (220) a porous layer from the metal layer, the porous layer having pores of length greater than ten times their breadth, and having a breadth in the range 10 nm-500 nanometers. The pores can be created by anodising, electrodeposition or dealloying. Then the sacrificial layer can be removed (230) through the porous layer, to form the micro cavity, and pores can be sealed (240). Encapsulating MEMS devices with a porous layer can reduce costs by avoiding using photolithography for shaping the access holes since the sacrificial layer is removed through the porous membrane.
