Products: LSD-155

Cutting Edge automated III-V Laser Diode and Wafer Processing

Speed, product quality and yield speak for themselves. Call us at 707-963-4111 or send us a message for information or a demonstration.

The hardware behind the LSD-155 is the key to its speed, precision and accuracy.

The LSD-155 can be configured to function with your existing equipment and process requirement by using common wafer holding media. These include 6″ and 7″ ring pairs, saw frames, the Loomis square frame, or vacuum plate. A variety of scribe tools, objective lenses, mandrels and breaking options are available to optimize the process to your specific application.

Key Advantages

Operator Productivity: Fewer transfer, alignment and process monitoring operations are necessary. Your operators can perform other essential tasks.

Reduced Transfer Operations: Minimal material handling means fewer alignment processes and higher levels of throughput.

Reduced Redundancy Requirements: 2 Loomis LSD-155 machines provide full process redundancy. Equipment limited to scribe only or break only require the purchase of 4 machines for full redundancy.


  • Automatically processes large grids, or arrays of laser bars for dicing, cleaving high quality mirror facets, and dicing wafers.
  • Uses advanced automation features that allow the high resolution
    vision system to process your wafers with micron-level accuracy.
  • A tuned, low-inertia scribing module allows fast peck speeds, while
    maintaining optimal peck quality.
  • Multiple cleaving options allow the LSD-155 to be configured
    to optimize cleave quality and speed.

    Software Control Package

    Loomis Industries software control package
    Ease of Operation

    The Loomis Software Control Package has the features for processing your material efficiently.

    Loomis dicing machines are driven by a computer system incorporating advanced positioning technologies, a real-time imaging system, and pattern recognition. The control software, developed with extensive customer input, accommodates specific user requirements, fully controlling speeds, pressures and other specifics about your wafer. The LSD-155’s highly refined vision algorithms find, align, and process your material with minimal operator supervision.

    Once a recipe has been developed, an operator only needs to load the material and press “Start”, allowing the machine operator to perform other tasks.

    Every facet and feature of a Loomis scribe tool exists to create the optimum scribe line. The leading edge of the diamond point encourages ductile flow of material around the point as it travels across the wafer, much like the flow of water around the keel of a boat.

    The trailing edge is polished to incredible sharpness and is responsible for the stress crack that travels down into the wafer. Lines created with our diamond scribe tools break cleanly and leave edges on the resultant dice that have integrity and strength.

    The dice are clean and ready for "die attachment" or coating without further processing.

    The Loomis scribe system outperforms all other scribing systems for repeatable optimal scribe lines.
