Code 6: Wafer Lot Traceability Code
The use of a one or two character Wafer Lot Traceability
Code is dependent upon the package size and is shown in
Table 3. The Wafer Lot Traceability Code in conjunction
with the Work Week Date Code provides unique wafer lot
identification.
Code 7. Year Date Code
The use of a one or two character Year Date Code is
dependent upon the package size and as shown in Table 3.
Code 8. Work Week Date Code
The use of a one or two character Work Week Date Code
is dependent upon the package size and is listed in Table 3.
Traceability and Date Code Tables
The coding and an example for each available package
type is shown in Table 3. Note that the smaller packages use
a one−character alpha code for the “Year”, and a
one−character alpha code for the “Work Week”. The alpha
codes are deciphered in Table 4.
