We all want faster, smaller and more energy-efficient smartphones. Unfortunately, physics is getting in the way.
Moore's Law, which states that the number of transistors on an integrated circuit doubles approximately every two years, is no longer held to be true. Tried and true methods for shrinking integrated circuits have nearly reached their economical implementation limit.
So scientists and engineers are working to find a way of pushing past that obstacle to deliver the next generation of circuit design.
One possible way of scaling up the performance of integrated circuits is 3D chip stacking.
Conventionally, the focus has been on simply shrinking the size of conventional 2D chips, to pack as much as possible into a single layer.
The 3D chip stacking builds on those efforts, by thinning these chips and stacking them on top of each other to produce high-speed and multifunctional systems.
These multilayered chips can incorporate vertical interconnects, transmitting data and power up and down the chip stack.
This not only increases the communication bandwidth between the chips in the stack, but also means the communication links between the various parts can be shorter. Shorter links means less delay and therefore better performance -and less power drain. A properly designed 3D stacked system can use as much as 70 per cent less power than a conventional chip.
But while this area of research has been gaining momentum over the past decade, with significant research from market leaders like Intel, much needs to be done to ensure that these far more complex chips function as seamlessly as needed.
In-depth exploration and testing must be done to learn how the close proximity of so many transistors, in three dimensions, affects the functionality of the chip in terms of its electrical, thermal and mechanical properties.
It is already known that the 3D design changes the stresses within the device. The thinned-down circuits do not behave in the same way, which can affect the transport of the electrons. And the stack design can get hot, too.
These factors can add up to create problems with the signals, voltage, material properties, device behaviour and material integrity, among other things.
The Masdar Institute has embarked on research that seeks to establish design and manufacturing guidelines for integrating electronics with photonic (eg. laser) circuits, and to characterise how thinning and stacking of the chips could potentially affect the behaviour of electrons and photons in a complex stacked system.
The major goal of this undertaking - which includes 12 individual projects - is to explore and illustrate the low-power features of 3D integrated microelectronics in a variety of computing, communication, storage and sensing design contexts.
My focus will be on the impact of stacking on the electronic circuits and their yield.
It is our hope that the sum of these projects will be a clearer idea of how to manage multifunctional, diverse integration of the chips, avoid thermal hotspots, and improve overall functionality in terms of power and speed.
We also hope to address the need for new computer-aided chip design algorithms that take account of the heating challenges.
And these projects will provide unique, functional and crucial hands-on experience for the professionals in the UAE's vibrant semiconductor industry.
It should help Abu Dhabi develop indigenous know-how in 3D chipmaking - an area that will soon be the crux of our rapidly evolving high-tech world.

Who are the Sacklers?
The Sackler family is a transatlantic dynasty that owns Purdue Pharma, which manufactures and markets OxyContin, one of the drugs at the centre of America's opioids crisis. The family is well known for their generous philanthropy towards the world's top cultural institutions, including Guggenheim Museum, the National Portrait Gallery, Tate in Britain, Yale University and the Serpentine Gallery, to name a few. Two branches of the family control Purdue Pharma.
Isaac Sackler and Sophie Greenberg were Jewish immigrants who arrived in New York before the First World War. They had three sons. The first, Arthur, died before OxyContin was invented. The second, Mortimer, who died aged 93 in 2010, was a former chief executive of Purdue Pharma. The third, Raymond, died aged 97 in 2017 and was also a former chief executive of Purdue Pharma.
It was Arthur, a psychiatrist and pharmaceutical marketeer, who started the family business dynasty. He and his brothers bought a small company called Purdue Frederick; among their first products were laxatives and prescription earwax remover.
Arthur's branch of the family has not been involved in Purdue for many years and his daughter, Elizabeth, has spoken out against it, saying the company's role in America's drugs crisis is "morally abhorrent".
The lawsuits that were brought by the attorneys general of New York and Massachussetts named eight Sacklers. This includes Kathe, Mortimer, Richard, Jonathan and Ilene Sackler Lefcourt, who are all the children of either Mortimer or Raymond. Then there's Theresa Sackler, who is Mortimer senior's widow; Beverly, Raymond's widow; and David Sackler, Raymond's grandson.
Members of the Sackler family are rarely seen in public.

Basquiat in Abu Dhabi
One of Basquiat’s paintings, the vibrant Cabra (1981–82), now hangs in Louvre Abu Dhabi temporarily, on loan from the Guggenheim Abu Dhabi.
The latter museum is not open physically, but has assembled a collection and puts together a series of events called Talking Art, such as this discussion, moderated by writer Chaedria LaBouvier.
It's something of a Basquiat season in Abu Dhabi at the moment. Last week, The Radiant Child, a documentary on Basquiat was shown at Manarat Al Saadiyat, and tonight (April 18) the Guggenheim Abu Dhabi is throwing the re-creation of a party tonight, of the legendary Canal Zone party thrown in 1979, which epitomised the collaborative scene of the time. It was at Canal Zone that Basquiat met prominent members of the art world and moved from unknown graffiti artist into someone in the spotlight.
“We’ve invited local resident arists, we’ll have spray cans at the ready,” says curator Maisa Al Qassemi of the Guggenheim Abu Dhabi.
Guggenheim Abu Dhabi's Canal Zone Remix is at Manarat Al Saadiyat, Thursday April 18, from 8pm. Free entry to all. Basquiat's Cabra is on view at Louvre Abu Dhabi until October
Mia Man’s tips for fermentation
- Start with a simple recipe such as yogurt or sauerkraut
- Keep your hands and kitchen tools clean. Sanitize knives, cutting boards, tongs and storage jars with boiling water before you start.
- Mold is bad: the colour pink is a sign of mold. If yogurt turns pink as it ferments, you need to discard it and start again. For kraut, if you remove the top leaves and see any sign of mold, you should discard the batch.
- Always use clean, closed, airtight lids and containers such as mason jars when fermenting yogurt and kraut. Keep the lid closed to prevent insects and contaminants from getting in.

How to come clean about financial infidelity
- Be honest and transparent: It is always better to own up than be found out. Tell your partner everything they want to know. Show remorse. Inform them of the extent of the situation so they know what they are dealing with.
- Work on yourself: Be honest with yourself and your partner and figure out why you did it. Don’t be ashamed to ask for professional help.
- Give it time: Like any breach of trust, it requires time to rebuild. So be consistent, communicate often and be patient with your partner and yourself.
- Discuss your financial situation regularly: Ensure your spouse is involved in financial matters and decisions. Your ability to consistently follow through with what you say you are going to do when it comes to money can make all the difference in your partner’s willingness to trust you again.
- Work on a plan to resolve the problem together: If there is a lot of debt, for example, create a budget and financial plan together and ensure your partner is fully informed, involved and supported.

Three ways to boost your credit score
Marwan Lutfi says the core fundamentals that drive better payment behaviour and can improve your credit score are:
1. Make sure you make your payments on time;
2. Limit the number of products you borrow on: the more loans and credit cards you have, the more it will affect your credit score;
3. Don't max out all your debts: how much you maximise those credit facilities will have an impact. If you have five credit cards and utilise 90 per cent of that credit, it will negatively affect your score.
