Dr. James Lu is the first IEEE Fellow “for contributions to three-dimensional integrated circuit (3D-IC) technology” and an IMAPS Fellow. He has led a number of research programs, including a large research program on 3D integration/packaging since 1999. Dr. Lu has more than 270 publications covering from micro-nano-electronics theory and design to materials, processing, devices, integration and packaging, including Si and GaAs devices, GaN LEDs and power devices. His current research interests include large-area assembly of LEDs, power devices, neutron detectors, micro-nano-electronics and sensors, and 3D integration of smart systems.

Director of New Product

Dr. Michael Conward is a mechanical engineer with over 5 years of experience in micro-scale manufacturing. He was the first to historically receive a B.S. in mechanical engineering from The George Washington University while also being a member of the Division I Men's basketball team. Dr. Conward later completed his PhD as a National GEM Fellow at Rensselaer Polytechnic Institute where he worked on an NSF-CAREER Award funded project and received the graduate-level Advanced Manufacturing Certificate. In addition, he previously had 2 years of service work experience within the advanced production, assembly & automation group for Boeing Research & Technology and received 2 meritoriously awarded invention disclosures. Dr. Conward is currently focused on the development of new products and establishing strategic industry/institutional partnerships to expand SelfArray’s technological capabilities.

Director of Operations

Dr. Pei-I Wang is a specialist of materials science and engineering with both research and industrial experiences in process development to drive high quality commercial products. Dr. Wang has expertise in sophisticated research technologies of micro- and nano-fabrication and characterization techniques to save costs and minimize yield loss. Dr. Wang’s research associated with low-temperature wafer bonding, semiconductor packaging material, and nanomaterials have been highlighted numerous times by electronics news when he was a research scientist in Center for Integrated Electronics at Rensselaer Polytechnic Institute. In 2011, he joined IBM microelectronics division and his development work in process integration was a key BEOL contributor for 22nm node success. Prior to joining SelfArray, he has been in roles of process integration for 7nm and 14nm nodes in GlobalFoundries. He is the author / co-author of 50 refereed publications and holds 5 granted / pending patents. Away from the technical work, Dr. Wang enjoys martial art training and holds black belt in shotokan karate.

The SelfArray Advantage

The direct view LED market is inhibited by expensive tri-color SMD LEDs with CAPEX intensive and time consuming manufacturing. The move to inexpensive, un-packaged, chip-on-board (CoB) LED displays is inevitable, and SelfArray’s patented directed self-assembly (DSA) technology is equipped to assemble such LEDs into pixel-arrays quickly and inexpensively.

How it Works

We are developing Directed Self-Assembly (DSA) using diamagnetic levitation. This leads to lightning fast assembly of millions of LEDs into an array. LED dies with a thin layer of pyrolytic graphite are deposited on a vibrating magnetic stage where they quickly orient themselves with the magnetic field. Once oriented, the LEDs can be transferred to the final PCB for bonding in a massively parallel fashion.

High Throughput Manufacturing

Much of the expense associated with a direct view LED display comes from the diode cost as millions of LEDs are required per each display. Small, unpackaged LEDs are cheaper than the traditional SMDs used in direct view LED displays today. However, it requires 3x the assembly time for unpackaged LEDs as red, green and blue dies are required.

This reinforces the need for our incredibly fast DSA approach to manufacturing. SelfArray’s technology is a massively parallel process and completely scalable. With it, manufacturing time becomes insensitive to the number or size of LEDs, the panel size, and pixel pitch.

Inexpensive LEDs

Our technology is perfectly suited for use with discrete, unpackaged LEDs for CoB applications. Without packaging, LEDs can be fed into our system directly after dicing, forgoing packaging costs. Our patent pending sorting technology is set up to quickly and efficiently in large numbers of unpackaged LEDs before self-assembly.

How We Make a Display

The DSA process is repeated three times with red, green, and blue LEDs. After DSA into an oriented array, the LEDs are transferred in parallel to a circuit board and flip-chip bonded. This forms an electrically connected array of R-G-B LEDs that we sell to display manufacturers.

Direct-View LED Manufacturing Technology Could Take a Big Leap - lightED, May 2nd, 2018

If SelfArray can continue to develop on the early successes, direct-view LED would become a principal competitor to OLED technology, which only represents a fraction of the overall solid-state lighting market. That makes it a much more palatable option because of the ability to use loose LEDs in a massively parallel process for a variety of display sizes.


SelfArray Receives NSF Award - Photonics Media, April 14th, 2018

LED technology developer SelfArray Inc. has received a National Science Foundation (NSF) Small Business Innovation Research Phase II Award to continue its work toward direct-view LED display manufacturing technology.

Direct-view LED displays, which are much brighter, have a better contrast ratio, and are more energy efficient than traditional LED displays, are currently being used for video walls, large indoor displays, and lighting fixtures. These displays use small, individual LEDs as pixels, and there are 24 million such LEDs in a single 4K display.


Funding the Clean Energy Revolution - NEXUS-NY, Apirl 1st, 2018

While cleantech angel investments and venture capital has seen a decline in recent years, there are some investors who believe in helping to deliver the next generation of reliable and affordable clean energy technologies with the potential to change the world. SelfArray, a NEXUS-NY 2017 graduate, recently attracted such attention from Excell Partners, HighTech Rochester and several alumni investors from Rensselaer Polytechnic Institute (RPI) totaling nearly $300,000 in seed funding. SelfArray also received a $750,000 Phase 2 SBIR grant.
