Arpelier

ClaudeCommunityby Arpelier

Arpelier is a process-flow workspace for semiconductor and nano devices, made for people and AI to work on together. Each step of a process flow (deposition, lithography, etch, implant, CMP and more) becomes a 3D structure you can inspect. This connector is the AI side of that workspace: Claude writes a process flow as Flow 1.0 JSON and checks it with the same engine the Arpelier web app uses, so it can measure the result instead of estimating it. With the connector, Claude can: - read Arpelier's docs for writing flows: process kinds and fields, material IDs, mask polarity and examples; - validate a flow with the web app's own parser, with each problem located in the JSON; - compute the structure up to any step and report material volumes and the surface height range; - take cross-sections with exact layer stacks (material, bottom and top in nm); - check whether two materials touch and their shared area, or whether points are connected; - list the material information that a 3D export (GLB, 3MF, STL) would carry; - make a link that opens a checked flow, with its computed result, as a new unsaved project in the web app. Six of the seven tools are read-only. The connector needs no account or sign-in and never opens or changes your Arpelier projects. It keeps data in two cases only: the computed structure (no names or notes) for up to one hour, to continue long or module-by-module calculations; and, for a link you ask for, the project made from the flow (with names and notes) and its computed result for 7 days. Anyone with a link can open it until it expires. Projects are saved only in the web app (arpelier.com). Results are geometric, with lengths in nm: Arpelier is for understanding, teaching and exploring process-structure relationships, not a fabrication recipe, a TCAD simulation or an electrical sign-off. Each calculation can use about 160,000 lateral grid columns and 400 executed steps; one longer than about 3 minutes continues over several calls.
