Study Sensor Performance in Rapid Thermal Annealing with Simulation

Bridget Cunningham | December 16, 2016

In rapid thermal annealing, a process step in producing semiconductors, measuring the temperature of a wafer is key. Without accurate measurements, overheating and nonuniform temperature distributions may occur, both of which impact the effectiveness of the process. This is why tools like the COMSOL Multiphysics® software give you the ability to analyze temperature distributions within an RTA design. From these results, you can better assess the performance of the sensor component and optimize its configuration to achieve accurate measurements.

When it comes to creating the next generation of flat panel displays and solid-state area lighting, organic light-emitting diodes, or OLEDs, may be used to help. While recognized for its various advantages, this emerging technology suffers from some weaknesses that reduce its overall efficiency. One such example is light loss, which is partially caused by the plasmon coupling effect. Looking to reduce the effect’s prominence in OLED devices, researchers from Konica Minolta Laboratory turned to the COMSOL Multiphysics® software.

I love my Philips Hue lighting system, which I bought over a year ago. The system allows you to set millions of different colors and thousands of brightness levels for up to 18 bulbs using a smartphone. You can also program the system to automatically turn on as you approach your residence, known as geofencing, or at specific times of the day. But how does the light quality compare to that of other lighting technologies?

Thanks to the Semiconductor Module and the Application Builder, developing custom optoelectronic simulation apps has never been easier. In this blog post, we show you how to turn a model of an LED device into a user-friendly application that can be used to assess the impact of different designs on the LED’s emission characteristics and performance. We also demonstrate the use of custom methods to manipulate the solution data, enabling the easy creation of bespoke analysis tools.

Simulation of 3D semiconductors has the potential to be extremely useful when developing and improving semiconductor technology by reducing the amount of experimentation and fabrication required to design complex devices. Modeling 3D devices is challenging as the length scales that must be resolved, combined with the nonlinear nature of semiconductor physics phenomena, often require computationally expensive simulations. Here, we share an example simulation of a 3D bipolar transistor and important advice for effective modeling of 3D semiconductors with COMSOL Multiphysics.

Bright light-emitting diodes (LEDs) are revolutionizing the lighting industry and blue LEDs in particular are ushering in a new age of widespread efficient LED lighting. The importance of blue LEDs was marked by this year’s Nobel Prize in physics, which went to the inventors. But, because bright LEDs are driven by larger currents, they suffer from reduced efficiency — a phenomenon known as LED droop. Using multiphysics simulations, we can investigate and understand the mechanisms behind LED efficiency.

When designing products on the nanometer scale, physics interactions that are considered negligible on the larger scale make their presence known. One such case where these forces must be taken into account is in the design of integrated circuits, where understanding and optimizing the effects of van der Waals forces, attractive forces, and surface tension become vitally important to creating a robust design. As technological advancements call for both the size of integrated circuits to decrease and the density of […]

In a paper titled “Choosing a Gate Dielectric for Graphene Based Transistors“, the applications of a semiconducting form of graphene are examined. As we have seen before, single-layer graphene is not a semiconductor, it is a zero bandgap conductor (a semimetal). Efforts are well underway to introduce bandgaps to graphene, which would make it semiconducting with a room temperature mobility an order of magnitude higher than silicon. The race is already underway to find applications for such a material once […]
