YGrowthMonitor for in-situ Monitoring
YGrowthMonitor is a powerful data aquisition system adaptable to numerous hardware configurations to fit your needs.

YWafer Inspector
Wafer mapping of defects and particles using high-resolution down to sub-micron levels. Includes brightfield (BF), darkfield (DF) and phosphorescence/photoluminescence (PL) modes.
​
Identifies particles, scratches, micro and hex pits, cracks, micro pipes, inclusions, stains, bumps, and PL dark/white spots.
​
Used in GaN-on-Si, SiC (epitaxial wafers and substrates), GaAs, InP, etc.
​
Mass production-proven with 4'', 6'', 8'' (soon 12'') SEMI standard loadports or SMIF handling.
MA Series
Proximity and Projection Mask Aligner

-
Proprietary high-speed image processing technology enables precise mask-to-wafer alignment.
-
Installing Automatic Mask Changer allows the system to support Mask Library.
-
Non-Contact Pre-Aligner achieves high-precision loading without damaging the wafer.
-
A parallelism correction mechanism achieves highly accurate control of the proximity gap between the mask and the wafer.
-
Proprietary mirror optical system integrated into Lamp House enables high uniformity and high irradiance across the exposure area.
MX Series
Maskless Exposure System

-
Direct imaging exposure is applicable to experimentation, research, prototype, small-lot production, or etc.
-
Applicaple to products such as semiconductors, electronic components, screen mask, metal mask, high-end PCB, high-density packaging, MEMS and FPDs.
-
No photomask is needed in the lithography process, which minimizes development cost and time lag to the market.
-
Also, custom system composition is available to meet the customers’ requests.

YChip Bonder
Discrete (one-by-one) device die bonder featuring eutectic, solder and epoxy bonding systems. Bonding is enabled to hoops, clips, lead frames and strips. Different handling methods (pin, gripper, flip-chip) available besides customized methods.
​
Mass backend production-proven with high throughput (up to 18,000 units per hour), available for 8'' and 12''.
