Syenta Localized Electrochemical Manufacturing (LEM)

Syenta is a Sydney-headquartered semiconductor technology company founded on research from the Australian National University. It develops high-resolution chip-to-chip interconnects for advanced packaging, aiming to ease the memory bandwidth bottleneck in AI hardware.

Its Localized Electrochemical Manufacturing (LEM) process deposits and patterns metal in a single step using a stamp electrode, producing sub-micron interconnects on packages larger than 1,000 mm2. The Achyon production tool is built on LEM, and the company says it fits existing manufacturing infrastructure.

• LEM process: Metal deposition and patterning combined in one step.
• Stamp electrode: Dielectric-patterned electrode that defines the interconnect.
• Fine redistribution layers: Targets 1/1 micron lines and spaces or finer.
• Large panels: Scaling to 510 mm and 600 mm panels.
• Achyon tool: Production tool for advanced packaging built on LEM.
• Demo access: Book a demo route listed on the site.

Advanced-packaging pilot lines, including those being set up in Southeast Asia, can evaluate LEM for redistribution layers and chip-to-chip links.

Substrate and panel-level packaging makers can test it for high-density interconnects on large formats.

Up to 40% fewer process steps, according to the funding announcement.

No redesign of existing fabrication infrastructure is claimed.

Higher interconnect density for better chip-to-chip bandwidth.

Claimed 3x throughput versus existing fabs on large panels (510/600 mm).

AI accelerators are limited by the bandwidth between logic and memory, pushing packaging toward finer interconnects on larger panels and glass or organic substrates. Southeast Asian OSATs entering advanced packaging need new process options that avoid fully rebuilding fab-grade lines.
