ResultData Result data B[m]
NOTE 1: One of these three OPT items needs to be specified.
9.6.1 The data structure of ResultDa ta is selectable with soft-switch as below:
(i) X,Y,BIN,...,X,Y,BIN
(ii) X,Y,N,BIN,BIN,...,BIN
(iii) BIN,BIN,...,BIN
9.6.2 The BIN data is a binary array and defined by an equipment supplier. For example, BIN data may include an
attribute of die (skip, on-wafer, etc.), pass or fail information and bin code.

10 Remote Commands
10.1 The purpose of this section is t o identify remote commands, command parameters, and valid commands
versus states in the processing state models. The specification in this section is provisional. This will be revised in
the near future.
10.2 Requirements
10.2.1 The prober must support the GEM-required remote commands. (Some of the GEM required remote
commands are restated here to define PSEM specific requirements.)
10.2.2 All the remote commands defined by PSEM are required.
10.2.3 The alphanumeric strings defined by PSEM for remote commands (RMCD) and command parameter
(CPNAME) are required.
10.2.4 If additional remote command s are supported, then the “Remote Command Versus Valid States” matrix
must be generated for these additional commands. Place an “X” in the table for each state in which a given
command is valid.
10.3 Remote Commands Descriptions
10.3.1 ABORT — This command terminates the current processing. ABORT makes no guarantee about completion
of the current process.
10.3.2 JOB_CANCEL — Instruct to d elete Prober Job before starting processing.
10.3.3 JOB_CREATE — Instruct to create Prober Job in batch processing unit (usually, unit of one cassette). This
allows management data for batch processing unit to be instructed to the prober.

10.3.4 PRE-DATA_DOWNLOAD — Downloads previous result data which instructs the details of processing for a
wafer.
10.3.5 ONLINE-LOCAL — Change the control state from On-Line Remote to On-Line Local.
10.3.6 ONLINE-REMOTE — Change the control state from On-Line Local to On-Line Remote.
10.3.7 PAUSE — Instructs the equipment to pause the processing. This command puts the prober into PAUSING
state when the current operation is completed.
10.3.8 PP-SELECT — This command instructs the prober to copy the indicated Process Program from non-volatile
storage to the prober’s Process Program execution area.
10.3.9 RESUME — Instructs the equipment in pause to resume operation. This command makes the equipment
resume the processing from a point where the processing PAUSED.
10.3.10 START — Instructs to start Pro ber Job.
10.3.11 STOP — Instructs the equipment to stop the processing. This command completes the current processing
unit, stops the equipment in safe state, and puts the equipment back to IDLE state. STOP has an intention of causing
a normal completion after the current unit is completed. Also, whether the processing unit is die or wafer can be
specified by the equipment constant Stop Unit.

10.5 Remote Commands and PSEM Process Model Mapping
10.5.1 Each remote command either can or cannot be executed depending on a state other than the control state.
10.5.2 The following table shows remote commands and the relationship between process state to be operated by
these commands and Prober Job state.
