About Qualtx Technology

Since its establishment in 1997, Qualtx Technology has been at the forefront of delivering turn-key control system solutions tailored to the semiconductor industry. A significant milestone was reached in the year 2000, when Qualtx transitioned into its present form as Qualtx Technology, Inc.

At the core of Qualtx Technology’s philosophy lies the belief that a cost-effective retrofit prevents the need for costly process tool replacements. This commitment drives us to provide complete replacements encompassing IO, signal wiring, and software components.

The central objective of our retrofit approach is to eliminate proprietary control systems and software. We do this by introducing off-the-shelf IO and source code*, facilitated by a new control system.

Qualtx brings profound expertise in designing electrical control systems and computer IO layouts. Moreover, our expertise extends to the development of cutting-edge system control software tailored for plasma etch and deposition equipment.

Qualtx Technology leads the industry in the retrofitting of PlasmaTherm systems, surpassing all other third-party companies. This establishes Qualtx as the foremost choice for third-party, open retrofit solutions.

Every Qualtx control system is built on a modern, open-standard technology platform. For I/O hardware, Qualtx uses the AutomationDirect P1000 PLC with Analog Input, Analog Output, Digital Input, and Digital Output modules, connected to the system controller via Ethernet.

The PLC serves purely as I/O — all system sequencing, recipe logic, safety interlocks, and process control run in the application software. That software is a fully custom Windows Forms application written in C# (.NET), running on Windows 11.

Because every component is off-the-shelf and customers receive the full source code, there is no proprietary lock-in — your team or any qualified engineer can maintain and modify the system independently for the life of the tool.

Note, there is an additional cost for the source code.
