Arrays

3

For the purposes of this analysis, “array” is defined as an array of contacts or 
vias (plugs). The contacts or vias are usually a metal like tungsten or copper 
which typically have polish rates higher than that of the surrounding array 
oxide. The basic composition of a sample array is illustrated in 

Figure 3.64

.

Using the ARRAY Analysis Routine

3

This routine is designed to perform analysis on both 2D and 3D Profiler data. 
The same set of input parameters are used for 2D and 3D data belonging to a 
single recipe, e.g., 2D slices from a 3D data set. 

The routine is intended for 

use with array profiles that have negligible recess and considerable 
erosion

. It can calculate both erosion and recession. 

Analysis Process

The analysis is performed on Normal data as described in the following 
sequence:

Figure 3.64

Sample Array

Field Oxide

Array oxide. Same 
chemical structure but has 
faster polish rates due to 
presence of plugs.

Metal-filled contact or via 
(plug). CMP polish rates are 
typically higher than that of 
array oxide.

Erosion

Recess

Dashed line represents 
surface with no erosion

CAUTION:  

The Array Analysis algorithm assumes that there will be a 

flat profile at the beginning of the scan and at the end of the scan. 
Therefore, the scan must start in the field oxide and end in the field 
oxide so that the required flat regions border the scan target.
