Need to identify a positive photoresist suitable for electroplating that achieves sub-micron resolution, high aspect ratio, and vertical sidewalls, while also optimizing metal adhesion on silicon wafers.

Suppliers claim photoresists are suitable for electroplating but do not provide clear, comparative data on performance in specific conditions like alkaline/acidic baths, resolution, aspect ratio, and sidewall profile, making selection difficult.

App Concept

PlatingResist Selector

An online platform that compares positive photoresists for electroplating applications. It provides side-by-side specs, user reviews, and performance data for different bath types, resolutions, and aspect ratios. Includes a recommendation engine based on substrate and process parameters.

Key Features

Searchable database of photoresists with filterable parameters (resolution, aspect ratio, bath compatibility, sidewall angle)
User-submitted performance reviews and micrograph images
Adhesion optimization guide for metal-on-silicon substrates
Comparison tool with side-by-side spec and cost analysis

Target Users: Process engineers and R&D technicians in semiconductor manufacturing, MEMS, and microelectronics fabrication facilities (companies of all sizes).

Revenue Model: Freemium with basic access; $99/month for premium including expert consultation and batch recommendation reports.
