STAT210example3.1: Plasma Etching Experiment

Description

An etching process is widely used when removing unwanted material after coating wafers with for example silicon dioxide, and a typical single-wafer plasma etching tool is a radio-frequency (RF) generator. An engineer is interested in the relationship between the RF power setting and the etch rate. This data shows the results from an experiment of four levels of RF power with five replicates.

Usage

STAT210example3.1

Format

A data frame with 20 observations (rows) and 2 variables (columns).

Column name Data type Description Values
[,1] RF_Power factor 4 settings of the RF power in W (160, 180, 200, 220)
[,2] Etch_Rate integer The etching rate in Å/min (530 - 725)

Details

This data is from Example 3.1 in Design and Analysis of Experiments. 9th Edition, EMEA Edition.
