ATMI Purchases Complete Tempus(TM) High-Productivity Combinatorial Research and Development Workflow from Intermolecular

ATMI, Inc. (Nasdaq: ATMI) and Intermolecular, Inc. today announced that ATMI has purchased Intermolecular’s complete Tempus™ Fluids-based High-Productivity Combinatorial™ (HPC) workflow for accelerated research and development (R&D). Expanding upon an initial Collaborative Development Program with Intermolecular, ATMI’s adoption of the Tempus Fluids-based workflow allows the company to leverage the HPC™ platform as a critical element in the ongoing transformation of its R&D methodologies. The purchase decision was based on early use of the Tempus Fluids-based workflow, which enabled ATMI to rapidly develop an improved process efficiency solution with a major foundry in Taiwan. Intermolecular is the semiconductor industry’s only provider of fully integrated combinatorial R&D technology powered by a set of systems and methodologies that radically accelerates discovery and integration of new materials, new process technologies and new device structures. "The future progress of the semiconductor industry requires the ability earlier on in the development phase to make rapid advances in IC materials,” said Doug Neugold, ATMI chief executive officer. "I’m enthusiastic about melding ATMI’s process efficiency mindset, strong customer relationships and technology portfolio with Intermolecular's technology to deliver faster resolutions to our customers’ materials challenges. Our rigorous, data-driven R&D process will be bolstered by the capabilities of the Intermolecular Tempus workflow, giving our customers better materials answers faster, for a fraction of the R&D cost they are used to paying.” Committed to implementing the most advanced semiconductor materials R&D, ATMI recognized the Tempus Fluids-based workflow’s ability to automate rapid parallel processing of multiple simultaneous materials-research experiments with fully automated wafer metrology and data analysis. "This agreement with ATMI, an industry-leading materials company, further validates our HPC systems and methodologies for transforming R&D productivity, which enable competitive differentiation for materials companies, equipment manufacturers and IC makers,” said David Lazovsky, Intermolecular’s chief executive officer. "The capabilities required of new materials, and the demands of device manufacturers, are growing at seemingly exponential rates,” said Tod Higinbotham, senior vice president and general manager of materials for ATMI. "With Intermolecular’s Tempus workflow, we are creating high-throughput materials R&D that is allowing us to assess hundreds — or thousands — of research combinations in the time it used to take to assess a dozen. This research efficiency helps us speed customers’ time to market while reducing their development costs.” The Tempus Fluids-based workflow includes a series of tools for applying HPC methods to a variety of applications, such as self-assembly processes, cleans, wet strip, wet etch and electroless deposition. Including Intermolecular’s proprietary informatics system for experiment design, development operations and data management, the Tempus Fluids-based workflow enables customers to maximize their return on R&D investment through economical high-speed development, integration and electrical testing of preferred solutions from an otherwise unmanageable number of alternatives. Intermolecular’s HPC technology is built on three pillars: Massively Parallel Processing, which automates and enables rapid processing of multiple experiments, Throughput-Matched Characterization, which includes fully automated metrology and e-test infrastructure to rapidly characterize the physical and electrical performance of developed technologies, and Automation and Analysis Informatics, a comprehensive, secure Web-based system that serves as a backbone for integrating processing and characterization tools into unified R&D workflows.
