7.1.6 * — Any format as above or those allowed in SEMI E5.
8 Object Definitions
8.1 The implementation of Strip Mapping defines one standard object, the Strip Map.
8.1.1 Strip Map Object Definition — The Strip Map is a dynamic object created and modified through the
assembly and test process. Each Strip Map Object is a logical representation of a manufacturing lead frame or
substrate and maintains the current processing state for the group of die attached to that physical leadframe or
substrate. Each Strip Map Object uniquely identifies a manufacturing leadframe or substrate using the ObjID
(StripID) object attribute. The object attribute notation used in Table 1 is described in Conventions, Section 7.
9 Requirements
9.1 Equipment Communication
9.1.1 Communication of strip maps between host and equipment shall use the SECS I or HSMS protocols.
Otherwise, some other general protocols, which are widespread in the data communication field, could be used as an
alternative. However, these are not covered in this specification.
9.2 Map Data Items
9.2.1 The Standard Map Data Items in Table 1 contain the standard data items that shall be used in all strip mapping
implementations.
9.2.2 The Strip Map Data Items in Table 2 are the data items and object attributes that will be used in the
implementation of strip mapping via the SECS/GEM interface as needed by each equipment type and process step.

Data Item Description / Settings Format
OBJSPEC A text string that has an internal format and that is used to point to a specific object instance.
The string is formed out of a sequence of formatted substrings, each specifying an object’s type
and identifier. The substring format has the following four fields: object type, colon character
“:”, object identifier, greater than symbol “>”, where the “:” is used to terminate an object type
and the “>” is used to terminate an identifier field. The object type may be omitted where it
may be otherwise determined. The final “>” is optional.
The OBJSPEC for the StripMap Object is a zero-length item. No specifier required.
A
OBJTYPE Identifier for a group or class of objects. All objects of this type must have the same set of
attributes.
Available object types: “StripMap”

OBJID Object Identifier A

ObjType The object type, “StripMap” RO Y A =
“StripMap”
ObjID The object. This is the StripID, FrameID or
equivalent.
RO Y A
CellStatus Cell Status is an array of values indicating the
value of each unit/package/device on a strip.
0 = Functional Good Cell; Good die placed on
Good cell.
1 = Unknown Cell Status.
2 = Defect/Non-functional Cell; the cell is
marked as defect by previous steps.
CellStatus shall be sent in an array of size
Rows × Columns in row major format with
respect to the OriginLocation.
CellStatus may be provided by the host to the
equipment as well as from the equipment to
the host.
Used in: Strip Map Upload and Strip Map

RW Y’
Either CellStatus or
CellGrade or both are
required if mapping is
to be used.
U1
CellGrade CellGrade is an array of values indicating the
classification of each unit/package/device/cell
on a strip. The process and equipment using a
‘grading’ scheme determine this classification
and the associated values. Examples of a
CellGrade are test bins, sort grades, package
grade, marking grades etc.
CellGrade shall be sent in an array of size
Rows × Columns in row major format with
respect to the OriginLocation.
RW Y’
Either CellStatus or
CellGrade or both are
required if mapping is
to be used.
U1
Columns The number of columns of (measured) device
matrix on substrate, that is the number of
devices on the X-axis of the map data. It is
required if the type of the map data is simple
array structure.

OriginLocation Coordinate system on substrate to address
devices. Location of the datum point or the
origin of the coordinates shall be one of the
following:
0 = Not currently supported
1 = Upper right – top side
2 = Upper left – top side
3 = Lower left – top side*
4 = Lower right – top side
5 = Not currently supported
6 = Upper right – bottom side
7 = Upper left – bottom side
8 = Lower left – bottom side
9 = Lower right – bottom side
* Default value is 3 (=Lower left – top side) if
this item is not present.

RO Y U1
Rows The number of rows of (measured) device
matrix on substrate, that is the number of
devices on the Y-axis of the map data. It is
required if the type of the map data is simple
array structure.
RO Y U4
SubstrateID A character code that may be printed or
encoded on the substrate, which uniquely
identifies the substrate, and can be used to
correlate the map with physical substrate.
SubstrateID is either StripID or FrameID.
RW Y A
BinGrade A BinCode (see SEMI G81) is a value
describing the grading of a die. BinGrade is
an array of bin codes used to describe each die
on the wafer.
BinCodeList shall be sent in an array size
Rows x Columns in row major format with
respect to the OriginLocation.
Typically used in: Strip Map Upload
RW N U1
DefectCode DefectCodes are a set of codes representing
defects that are detected at each process step
by equipment or a human.
DefectCodes shall be sent in an array of size
Rows × Columns in row major format with
respect to the OriginLocation.
If there is no defect, the DefectCode is 0
