The market for LEDs and laser diodes (LDs) will continue its significant growth, driven by multiple applications such as displays, signage, lighting, materials processing, UV curing, purification, sanitation, laser printing, image scanning, data recording, biotechnology, and medicine. As a result, companies, from materials to semiconductor ones, want to build new LED or LD businesses or expand current product portfolios. However, in an increasingly competitive environment, only companies that can better manage risks and get to market faster will succeed.

The PARC solution

Fortunately, partnering with PARC, a recognized world leader in the LED and LD fields enables customers to:

  • Lower costs
  • Create differentiated products or add value to current offerings
  • Investigate ideas to improve device performance
  • Transfer processes and prototypes to mass production
  • Acquire device technology and expertise
  • Complement in-house efforts to accelerate innovation
  • Collaborate with one partner (i.e., PARC) for their needs

Customers can take advantage of PARC’s on-site, fully integrated, end-to-end infrastructure, skills, and experience. Our wide range of offerings include:

  • Growth: Recipes scalable to high-volume production, optimization, heterostructures
  • Device: Complete fabrication and prototyping, advanced characterization, modeling, design, testing, computational physics
  • Substrate & materials: Evaluation and benchmarking (epi test devices), computational physics
  • Knowledge: Personalized hands-on demonstrations and know-how transfer, analysis of device, growth, and fabrication challenges
  • Technology transfer: New or established technologies
  • Custom requests

PARC’s offerings are based on a world-class team, deep ground-breaking technical experience, and fully integrated infrastructure onsite.

At the forefront

PARC has been on the cutting edge in this area for decades and continues to lead today. We have been the first to accomplish many feats, which have provided us with the deep expertise and proven innovation methodologies to specifically address your needs.  Here are a few examples of PARC firsts:

  1. Structure and electronic properties of dislocations and extended defects in GaN
  2. Laser diodes with InGaN MQW (first outside of Japan)
  3. Theory of GaN surface structure and surfactants
  4. DFB InGaN laser diode
  5. InGaN MQW laser diodes transferred to copper substrate via laser-lift-off
  6. Q-switched two-section InGaN laser diode with integrated electro-absorption modulator
  7. UV laser diode with AlGaN MQW
  8. Laser diode on bulk AlN
  9. Silver and ITO clad nitride semiconductor laser diode
  10. Optically pumped AlGaN MQW lasers on bulk AlN down to 267 nm

Innovation in action: from concept to market

PARC has successfully applied such leading-edge accomplishments and capabilities to developing LEDs and LDs for commercial clients. One recent engagement was with DOWA Electronics Materials Co., Ltd., a semiconductor materials company seeking to move into a new business based on UV-A LEDs. By working intimately with PARC -- beyond just IP licensing -- DOWA rapidly gained the know- how, prototypes, and technology for UV-A LEDs, enabling the company to publicly announce its first UV-A LED-based products within just nine months of starting work with us. Furthermore, the custom collaboration with PARC enabled DOWA to further its internal R&D competency in UV-A LEDs so it would be able to sustainably grow and advance this new business.
