What It Is

株式会社エルテック（LTech） provides software solutions for semiconductor manufacturing equipment. Centered on the LTAnna platform, it brings together equipment control, communications, PLC integration, GUI, 3D simulation, and a dedicated IDE. It is more of an industrial equipment software development foundation than a general-purpose developer tool, with target scenarios focused on semiconductor equipment control and SECS/GEM communication.

Core Capabilities

LTAnna is a Lua script execution and equipment control engine. It supports mechanisms such as Startup.lua, OnStart(), separation of UserScript/UserDll, and CSV logging, and it can expose public static Anna functions from C# extension DLLs for Lua to call. The LTGem Series covers SECS/GEM, HSMS, SECS-I, and SECS-II message handling as well as GEM state management, while also providing GEM server, simulator, and log viewing capabilities. DeviceMap provides a client/server-style typed shared device foundation for abstracting PLC device values, with support for event-driven access. Anny Editor is a dedicated IDE offering Lua editing, DLL parsing, autocomplete, parameter hints, and project execution control. Anna3DViewer can reproduce transfer robots and equipment mechanisms in 3D, helping with validation without physical hardware.

Pricing and Licensing

The page does not disclose pricing, licensing model, trial version, payment methods, or whether it is open source. Judging from the descriptions of “パッケージソフトウェア” and contracted development, it is more likely to follow a commercial software plus project delivery model, but this needs to be confirmed with the vendor.

Pros and Cons

Its strengths are its strong vertical focus and its ability to connect control logic, SECS/GEM, PLC, GUI, simulation, and IDE into an integrated whole, which has practical value for semiconductor equipment development teams. The layering of Lua and C# DLLs also supports scripted control and reuse of low-level functionality. Its weaknesses are the limited amount of public information and the lack of API documentation, examples, compatibility details, deployment methods, and support SLA. The company lists 5 employees, so its long-term support capability and ability to deliver large-scale projects should be evaluated.

Who It’s For and Access from China

It is suitable for semiconductor manufacturing equipment vendors, FA control software teams, and engineering projects that require SECS/GEM, PLC integration, and equipment simulation. It is not suitable for teams looking for a general-purpose IDE, cloud development platform, or open-source SDK. Access from China is not reflected in the text, so it is considered unknown.
