Hybrid Integration with MOEMS
December 31, 1969 |Estimated reading time: 2 minutes
WEBSTER, N.Y. and PALO ALTO, Calif. — Xerox scientists are conducting advanced research to fabricate small optoelectromechanical devices that will offer a low-cost, accurate image registration. The technological advances are expected also to have applications in optical switching for telecommunications and industrial automation.
These miniscule, yet reliable devices, called micro-optoelectromechanical systems (MOEMS) integrate optical, electrical and mechanical elements in a package no bigger than a microchip. They contain intelligence that allows them to sense optically and then control what is going on around them by generating, modulating, guiding, switching and detecting light.
For MOEMS applications requiring optical emitters, Xerox scientists have integrated miniature laser diodes and optics on an IC through a flip chip bonding technique developed by Decai Sun and Michel Rosa at the Palo Alto Research Center (PARC), a subsidiary of Xerox Corp.
"A photoreceptor belt can vibrate like a taut rubber band," said Joel Kubby, principal researcher on the project, of Xerox Wilson Research Center in Webster, N.Y. Instead of trying to hold the belt steady while the four colors comprising the color image are laid down (cyan, yellow, magenta and black), Xerox scientists are investigating the use of sensors to detect the belt's exact position and then to accommodate its movement by using MOEMS to steer the laser beam to that position in laser printing applications.
Xerox is one of the multidisciplinary team of end users and suppliers collaborating to develop this novel, yet broadly enabling process for the design, fabrication and assembly of MOEMS. Other companies in the consortium include Maxim Integrated Products, Conventor Inc., Microscan Systems Inc., Optical Micro-Machines Inc. and Standard MEMS Inc.
Specialty R&D Labs Fill Industry Niche Following is part one in a two-part series about specialty R&D laboratories. Look for profiles of three other laboratories in the November issue of SMT.
VISTA, Calif., BILLERICA and FRANKLIN, Mass. — It seems that the current outsourcing trend by many companies is to launch a specialty R&D laboratory. Take Vista, Calif.-based Palomar Technologies' Process Development and Prototyping Services, launched in June. The company expanded its applications engineering division and test facilities, and, bucking an industry trend of downsizing, increased its Process Development and Prototyping Services staff.
Equipment and subprocesses that are part of the service include electron and scanning acoustic microscopes, a cleaning system, a forced convection soldering oven, and laser diode parameter analyzer.
According to Palomar, startup companies without the resources provided by the laboratory can benefit from the service. Additionally, established companies can use the service either to make up for the downsizing that has been sweeping the electronics industry or to build a product outside their core technology.
At Billerica, Mass.-based Emerson & Cuming, an applications laboratory housed away from the company's normal R&D laboratories in an area with restricted access allows customers to complement their own R&D efforts and bring products to market faster.
The laboratory, which opened in December 2000, can build full prototypes and simulate the actual production environment using equipment such as Universal's GMSxs pick-and-place machine and an inert gas blanketed reflow oven in which assembled ICs can be cured in a non-oxidizing environment.
Franklin, Mass.-based Cookson Electronics launched the Process Development Group (CEPDG) in 1999 in Foxboro, Mass. According to company literature, the lab's mission is to perform product analysis and performance evaluations, develop advanced manufacturing processes, and take a leadership role in creating and improving standards and methodology for the electronics industry.
