Care Area Wizard Outputs
After the user is done defining selection sets he will want to produce output
that can be sent to KLA-Tencor’s inspection equipment. All of the output generated by CA Wizard is placed into
a single output directory which makes it easy to transfer to another
application. The following outputs are generated as a group:
CAF - Care Area File. Rectangles defining all of the care area regions organized by
layer/datatype and by cell.
CONFIG.CSV - an ascii file containing information about the two registration sites.
MARK1.TIF, MARK2.TIF - TIF images of the registration sites. These are monochrome images (user
control black on white or white on black
MAPPING.CSV - a mapping file which maps layer/datatype to selection set.

The CONFIG.CSV File
The configuration file is always called config.csv and is a comma delimted ASCII
file. It contains information about the two images clips of the registration
marks in the following syntax:
Clip1,mark1.gif
Clip2,mark2.gif
orientation,UP | DOWN | LEFT | RIGHT
DataType-RegistrationSite1,255
LayerId=RegistrationSite1,255
DataType-RegistrationSite2,254
LayerId=RegistrationSite2,254
| ||||||||||
The data type and layer assignments for registsration sites 1 and 2 are set in
the CA Wizard Preferences.
| ||||||||||
The MAPPING.CSV File
The mapping file is called mapping .csv and it is a comma delimited ASCII file.
It contains information in the following syntax:
DataType,LayerId,grouptype,Regionid,groupname,GroupCode,GroupOverlapPriority
0, 1, CA, R4, SRAM1, 1, 42
0, 4, DCA, R2, DUMMY, 10, 43
| ||||||||||
Layer ID - this is the layer number for the selection set
Data Type - this is the datatype for the selection set
Group Type - CA = Care Area, DCA = Don;t Care Area
Region ID - don’t know what this is
Group Name - assume this is the selection set name
Group Code - don’t know where this comes from or what it means
Group Overlap Priority - a positive interger (must be unique) indicating the
overlap priority of this layer.
| ||||||||||
The CA File
| ||||||||||
The CA File (.caf) contains the Selection Sets (also known as Groups). Each
group consists of one or more rectangles. All rectangles for a given group are
stored on a common layer and datatype and contained within a single cell. The
cell’s name is the Group Name.
| ||||||||||
| ||||||||||
There are two “special” cells in the file to hold the registration information: regsite1 and regsite2.
These each contain a single rectangle defining the extents of the registration
polygon. The layer/datatype used for the two registration sites should coincide
with layers/datatypes used for care areas.
The name of the top level cell in the care area file is user defined.
