AM e-Beam Metrology for Layer-to-Layer Overlay
This research method incorporated high-resolution imaging, physical measurement and a center of gravity algorithm to achieve sub-nm precision to indirectly obtain true overlay. Using an accurate and non-destructive metrology technique called random located SEM overlay (RLSO) (that selectively samples regions across the field of interest to confirm actual overlay offset) was a core part of the study. These regions were measured with e-beam technology that is the only system with resolution high enough to generate overlay data from the devices.

EVG Nanoimprint Lithography for 3D Optical Structures
Thermal scanning probe lithography, the technology behind NanoFrazor, was invented at IBM Research in Zurich and acquired by SwissLitho AG. This maskless, direct-write lithography approach involves spin-coating a thermally sensitive resist onto the sample surface before patterning. A heated tip is then used to decompose and evaporate the resist locally while simultaneously inspecting the written nanostructures. The resulting arbitrary resist pattern can then be transferred into almost any other material using lift-off, etching, plating, molding or other methodologies. The target markets for this venture include photonics, data communications and augmented/virtual reality.

Hubbell Control Solutions Expands Lighting Control Platform
The Distributed Network Architecture (“DNA”) of NX aims to eliminate common operational dependencies on software, gateways and servers found in other lighting control systems by distributing control logic to each lighting control device.
NX is available as a wired and wireless solution, a standalone luminaire-based control, a small room network or a building-wide system across indoor and outdoor commercial, architectural and industrial spaces. NX connects intelligent devices, such as luminaires, room controllers, panels, occupancy sensors, photocells, wall switches, relays and dimmers.
Applications include occupancy and vacancy, scheduling, daylight harvesting, 0-10V dimming, color temperature control, task tuning and occupant control.
Details on the complete set of controls for fixtures, rooms, buildings and all other lighting applications can be accessed on the Hubbell Control Solutions website.
Nordson Enhancing Performance of PCBAs Using Plasma Treatment
Optimized plasma processes enable 3D-packaging technologies that are useful and reliable. Plasma treatment cleans surfaces prior to bonding to enhance adhesive bonding and wire bonds and enhances the flow of underfill materials for flip chip packages, providing better bonding and more reliable packages. It is beneficial prior to conformal coating for improved adhesion and flow characteristics. Plasma deposition of hydrophobic films onto PCBAs have been shown to improve long-term stability, and can be an alternative to conformal coatings.

Yamaha Modular Mounter with Overdrive System
The Overdrive Control system enables the rotary heads to assemble PCBs simultaneously with no wait time and allows both placement heads to pick from each other’s component supply, on either side of the machine, and place them on the same board simultaneously and without restriction. Overdrive functionality lets users adapt to varying production requirements without reconfiguring the line.
