bdspots: Breakdown Spots in Microelectronic Materials

Description

A list of three point patterns, each giving the locations of electrical breakdown spots on a circular electrode in a microelectronic capacitor.

Usage

data(bdspots)

Format

A list (of class "listof") of three spatial point patterns, each representing the spatial locations of breakdown spots on an electrode. The three electrodes are circular discs, of radii 169, 282 and 423 microns respectively. Spatial coordinates are given in microns.

Details

The application of successive voltage sweeps to the metal gate electrode of a microelectronic capacitor generates multiple breakdown spots on the electrode. The spatial distribution of these breakdown spots in MIM (metal-insulator-metal) and MIS (metal-insulator-semiconductor) structures was observed and analysed by Miranda et al (2010, 2013) and Saura et al (2013a, 2013b, 2014).

The data given here are the breakdown spot patterns for three circular electrodes of different radii, 169, 282 and 423 microns respectively, in MIM structures analysed in Saura et al (2013a).
