Stone Pillar Product Overview
Stone Pillar Technologies' Stone Pillar SuiteTM is a complete software framework that automates many of
the tasks involved in semiconductor technology development. Stone Pillar Suite
provides unique functionality that allows process technologists to focus on
analysis, rather than tedious and error-prone data mining and document
The following tools are available for the Stone Pillar Suite framework. Each of these
tools is built around a Java based extensible "plug-in" architecture that facilitates
deployment in a state-of-the-art distributed client-server workgroup environment.
Stone Pillar DeviceTargetManager is used to set up supported devices and related
limits within the Stone Pillar Suite Data Server. These supported devices can be linked to
subsequent test chips, test plans, and experimental data and the limits can be
invoked for inclusion in automatically generated reports.
Stone Pillar TestChipBuilder and ChipEditor offer a complete, integrated, graphically-driven
system for automated test chip generation. TestChipBuilder can automatically generate
test structures with varying geometries from an extensive library of device templates.
capabilities. Devices can be automatically placed and routed within a pad ring.
The resulting modules, or pad frames, can then be combined to build up an entire
Entire test chips can automatically reflect ongoing updates to global DRC rules.
The generated structures can be streamed out as GDS2 or converted to Cadence® SKILL,
to support scalable SPICE models within a CAD environment.
Electrode names and positions are maintained within Stone Pillar Suite,
which facilitates automated electrical test plan development. Association between
electrical test results and test structure layout parameters is automatically created and
maintained by Stone Pillar Suite. This enables easy, automated recreation of plots or data views
of interest (such as scatter plots of Leakage versus Poly-Composite Overlap), which speeds
design rule verification and optimization.
TestChipBuilder also creates up-to-date and complete documentation of individual
geometrical device parameters and complete test chip configurations.
Stone Pillar TestPlanManager is used to automate test plan creation and
eliminates time consuming and error-prone hand coding of test plans.
TestPlanManager retrieves information about test chips created by either
TestChipBuilder or externally produced. TestPlanManager then creates any
needed device instances within the Stone Pillar Suite database and presents
the devices and their parameters to the user in a tabular form.
The user can then select from libraries of available tests and apply these to
one or more devices. The tests can be grouped for convenience and flows
such as complete or reduced test flows can be stored within the Stone Pillar Suite
Once the desired flows have been created, TestPlanManager will automatically
create test plans that can be run on standard test equipment.
Stone Pillar BenchTestManager is used to facilitate and automate bench testing
by providing ready access to test chip and wafer details, providing automated
and semi-automated test execution through test flows and plans, and storing the
test locations and test results to enable rapid selection of previously untested
die and devices.
Stone Pillar DataAnalyzer provides rapid, complete and easy-to-use
capabilities that facilitate the review, filtering, and visualization of
test data via spreadsheet, scatter plots, box plots, statistical summaries
and timelines of parameter drift. An automated and comprehensive split lot
analysis environment accelerates your timeline to generate lot reports, draw
firmer conclusions and speed learning cycles. Within this environment, you
can easily review test chip layout, process flow revision, target values,
and split experiment details for an individual data point or a complete
experiment with the click of a button.
Stone Pillar ExperimentBuilder enables the rapid definition of split lot
experiments with reference to a baseline process flow. Experiments are defined with
a familiar matrix editor and are stored in the Stone Pillar Suite database for analysis,
alongside future electrical test results. Split details are automatically linked with
experimental parameters and test structures.
Stone Pillar ReportGenerator automates the creation of standard reports
based on information present in the Stone Pillar Suite Data Server.
