“…A green micro‐LED display with VGA (video graphics array) resolution was demonstrated in 2012 with pixel pitch of 15 μm . Prof M. D. Dawson's team reported their micro‐LED work in 2004 with resolution of 64 × 64 and pixel pitch of 30 μm . Then they reported individual addressable micro‐LED displays with Si CMOS drivers in 2009.…”

High pixel per inch and high‐resolution micro‐LED displays are attracting more and more attentions. The increasing pixel number requires a large amount of bonding pads and brings huge difficulties to micro‐LED system design and lowers power efficiency as well. It is urgent to integrate row and column driving circuits onto the micro‐LED panel. Here, we report a fully integrated active matrix programmable micro‐LED system on panel (SoP) with ultraviolet and blue emission wavelengths. The micro‐LED SoP has a resolution of 60 × 60 and pixel pitch of 70 μm. The micro‐LED SoP was achieved by integrating micro‐LED arrays with silicon‐based p‐channel metal‐oxide semiconductor driving panel using fine‐toned flip‐chip bonding technology. With fully integrated scan and data circuits, the number of bonding pads was greatly reduced from 136 to 28, and large amount of metal interconnection lines were saved. The micro‐LED SoP panel was mounted on a periphery driving board, and representative characters were displayed successfully.

“…Specifically, these techniques can be applied to the deposition of a micro optical element such as micro lens 1 micro LED, 2 or micro sphere laser. 3,4 In micro manipulation, the adhesional force is dominant since it is proportional to the first power of the object size, 5,6 whereas the gravitational force is proportional to the third power.…”

Pulse voltage determination for electrostatic micro manipulation considering surface conductivity and adhesion of glass particle

et al. 2015

A model with surface conductivity and adhesional force is proposed to investigate the mechanism for electrostatic micro manipulation of a dielectric object using a single probe. The manipulation system consists of three elements: a conductive probe as a manipulator, a conductive plate as a substrate, and a dielectric particle as the target object for manipulation. The particle can be successfully picked up/placed if a rectangular pulse voltage is applied between the probe and the plate. The reliability of the picking up/placing operation is improved by applying a pulse voltage that is determined by a theoretical model considering surface conductivity and adhesion. To verify the theoretical prediction, manipulation experiment is conducted using soda-lime glass particles with radii of 20 μm and 40 μm.

We report here details of the epitaxial lateral overgrowth (ELOG) process for embedding a Ta 2 O 5 /SiO 2 multilayer high reflector micro-mirror array (MMA) in the GaN. The process was aiming for purpose of applying the MMA on the micro-light emitting diode (micro-LED) for light extraction enhancement of the micro-LED. A two-step ELOG process with different temperature and pressure to achieve high lateral growth rate and low vertical growth rate was implemented and the two-step ELOG process was followed by a slow growth rate process to complete embedding the MMA. #
