Section 3: Configuring a Wafer ID Application In-Sight
®
1700 Series Wafer Reader

3.2 Basic Concepts
Wafer reading recipes created using In-Sight are called jobs . Each job can contain up to
10 unique reading configurations, called Configs . Each Config specifies a type of wafer
mark, a checksum, the string fielding, light settings, and other information. An automatic
tuning operation can be used to optimize Config settings for maximum reading reliability.
Jobs can run multiple Configs in a retry sequence until a successful read is achieved, or
the mark cannot be read within the time permitted. Optionally, Configs can be tuned
automatically during runtime if the retry sequence fails to report a successful read.
When a Config is tried, it reports a string of characters for successful reads, or a string of
asterisks (***) or partially read characters and question marks for failed reads. In either
case, a read score is reported.
All of the steps necessary to configure a standard wafer ID application are performed in
the user interface that loads automatically when you connect to a networked wafer reader
using a Java-enabled web browser, as described below.
3.3 GUI Overview
The user interface that loads in the web browser when connecting to a wafer reader is
divided into five main areas:
The File tab is used to open, save and delete job (.JOB) files. The File tab also
provides quick File Transfer Protocol (FTP) access to files in the wafer reader’s flash
memory.
The Setup tab is used to select Config settings, which can then be optimized through
the automated tuning process.
The Options tab is used to specify various runtime settings that determine how the
job will execute. These settings include the source of the image acquisition/read
trigger, the retry method to use for enabled Configs, and the data format and output
destination of read results. The Options tab also provides a hyperlink to the System
Settings page (see Section 6: System Settings).
The Run tab is the runtime view of the wafer reader’s operation, showing the most
recent read results and statistics for the Configs enabled in the job. The Run tab is
the default view whenever a wafer reader is accessed through a web browser, and is
the only view allowed when a wafer reader is Online.
Status bar . The status bar shows (from left to right) the Host (Host Name or IP
Address) for the connected wafer reader, the Access level for the current user (Full,
Protected or Locked), the name of the Current User , and the name of the user that is
logged on with Admin/Operator privileges.
NOTE Only one Admin/Operator user at a time may log on to the browser interface.
