Abstract

Visible light communication (VLC or LiFi) has been a topic of intense research after the idea was proposed in 2011. To date, a data rate of multiple 100s Mbps has been demonstrated using LEDs or micro-LEDs as transmitters. At KAUST, we are developing laser-based device and system technologies for Gbps VLC and underwater wireless optical communication (UWOC). In this talk, I will give a brief overview on recent deployments of Gbps VLC and UWOC systems. I will focus my discussion on recent developments of high-speed lasers, and self-powered and omnidirectional receivers for VLC and UWOC.

Abstract

A microdisplay has a wide range of applications in smartphones, smartwatches, AR/VR systems, Helmet Mounted Displays (HMD), Head-Up Displays (HUD). Their individual pixel elements typically consist of a large number of micro-LEDs (μLEDs). Current μLEDs are far from satisfactory, as a number of fundamental challenges cannot be met by any existing technologies. Visible light communication (VLC) is an emerging technology that offers approximately 300 THz of license-free bandwidth that is four orders of magnitude larger than that available in current RF-based Wi-Fi or 5G. Unfortunately, the current approaches to the fabrication of VLC are substantially limited to μLED fabrication technologies. The conventional approach to the fabrication of μLEDs requires a combination of a standard photolithography technique and subsequent dry-etching processes. This approach unavoidably introduces damage during the dry-etching and following processing, severely degrading the optical performance of μLEDs. This issue becomes increasingly severe as the μLED dimensions decrease. The Sheffield team has developed a direct epitaxial approach to the fabrication of ultra-small and ultra-compact μLEDs for microdisplay application, leading to the 1^st demonstration of ultra-small green μLEDs (3.6 μm diameter) without using dry etching (ACS Photonics 7, 411 (2020)), where our μLEDs exhibit a record EQE of 9% and the narrowest spectral linewidth (ACS Nano 14, 6906, (2020)). Our epitaxial integration has also led to the demonstration of a record modulation bandwidth of 1.2 GHz for VLC application (ACS Appl. Electron. Mater. 3, 445 (2021)) and 1^st monolithically integrated μLEDs/HEMTs microdisplay on a single chip (Adv. Mater. Technol. 9, 2100214(2021)).

Abstract

Component level packaging is needed to protect integrated circuits from mechanical damage and to provide convenient electrical contacts for incorporating the circuits into larger systems.  The choice of a type of package typically involves a trade-off between performance, reliability, and costs. A wide variety of materials: plastics, metals, ceramics, composites, etc., are used in packaging and there are many packaging technologies in use. For a better understanding of how packages degrade and eventually fail, models are being developed to describe their behavior. Calculating the thermal and mechanical properties of packages can be challenging because the dimensions of the smallest features inside a package can be much smaller than the size of the package thus requiring a fine spatial grid. The relevant time scales can range from nanoseconds for electronic signals to weeks for the diffusion of water in a package. These disparate and length scales often require that approximations be made. Some recent research on microelectronics packaging will be discussed.

Peter Hadley is a device physicist who has investigated superconducting circuits, single-electron circuits, carbon nanotube and single-molecule devices, organic semiconducting devices and inorganic semiconducting devices made from Si, and SiC. The current focus of his research is on understanding defects in semiconductors. He is the director of the Institute of Solid State Physics at the Graz University of Technology.

Abstract

The growth of GDP for any country relies on the ability to produce goods i.e. commodities or manufacturing.  In the last 10 years, although growing, the rate of the manufacturing sector in the country is slowing down and almost reaching its maintenance level. This can relate directly to the shift of demand from Western World consumers to cheaper affordable products from China and more recent competitors like Vietnam and Indonesia.  Without manufacturing, the Malaysian E&E sector will continue to be diluted within the global supply chain. Therefore, how can we stay strong together riding this journey?

Abstract

Nanotechnology is making a revolution in manufacturing and production, creating new materials and products through novel processes for commercial purposes. New products based on nanotechnology with novel characteristics are continued to grow and benefit society like nanomaterials, particularly carbon nanotubes or graphene could offer semiconductors. Technology development towards experimental development research is moving forward on producing new products or improving existing products or processes. A newly developed method to reduce the size of semiconductor materials, dramatic improvements in the chemical, physical and structure properties of these materials continue to arise. Thus, minimizing the size in nanometer-scale of semiconductor materials has been shown to maximize the performance of semiconductors for their application in a wide range of material applications such as in energy sector, electronic device systems, automotive and etc.

Abstract

In the business world, this is the world of the fittest to survive. To this, businesses around the world always seek for improvement to stay competitive as demand from the customers particularly in the terms of price reduction. We can see the price of a computer in Malaysia. In the mid-80s, a white box PC was sold at RM 5000 at least. There was no laptop or notebook at that time. Tablet is far from available. Now a fairly good PC can be obtained at less than half this price.

In this session, it will be a sharing looking at both the hard and the soft management tools in manufacturing to stay competitive. Those who are able to exploit and constantly drive for changes that lead to improvement, innovation and breakthrough will always be in the game. Those who are not able to be in this game will eventually be out of business or being acquired by others. Some of these companies are history and some had created history.
