Semiconductors are compact, powerful electronic components that include elements like chips and sensors, that process data, execute commands, communicate with other devices, connect to the internet and store memory. Whether optimizing agricultural practices with autonomous irrigation sensors or powering pacemakers that regulate heartbeats, semiconductors enable transformative technologies. As we become increasingly more connected, advanced semiconductors are essential for enhancing the efficiency and impact of the devices that link us and shape our daily lives.

Overcoming challenges with next-generation innovations 

As the electric vehicle (EV) market accelerates, it is pushing the boundaries of semiconductor technology to address pressing challenges like range anxiety, insufficient charging infrastructure and slow charging speeds. Innovations in this sector are focused on creating more efficient semiconductors that improve battery life, reduce the weight of power devices and tackle critical issues affecting EV performance and infrastructure. 

The shift to silicon carbide for long-lasting semiconductor solutions 

Recently the semiconductor industry has transitioned from using silicon-based (SI) slurries to silicon carbide (SIC)-based slurries for semiconductor chemical mechanical planarization (CMP). SIC slurries offer significant advantages over traditional slurries due to their electrical properties, including: 

• Higher thermal conductivity: SIC materials provide better heat management during the polishing process, ensuring stable conditions. This helps prevent wafer damage, improves polishing accuracy and boosts reliability.  

• Improved efficiency in power devices: Using SIC slurries in CMP allows systems to handle higher voltages and temperatures, improving efficiency and performance.  

• Greater mechanical hardness: SIC is mechanically harder than silicon, which enhances its longevity and speed in smoothing wafer surfaces because it can withstand great force without deforming. This combination makes it more durable, scratch resistant and better at delivering uniform results.   

• Lower energy loss and better performance: Silicon semiconductors waste energy as heat but SIC semiconductors can run at higher frequencies and temperatures, reducing energy loss and enhancing improved performance. 

• Thinner wafer production: SIC enables smaller and more compact semiconductor devices that are both lightweight and durable. 

• Compatibility with high-voltage applications: EVs and renewable energy systems require materials that can handle high-power demands and SIC is well suited for these challenging applications. 

Vibrantz is making strides in SIC slurries

With over 60 years of expertise in surface finishing technology, Vibrantz’s research, development and analytical resources empower us to drive innovation in the industry. Our new acidic permanganate SIC slurry offers high removal rates (from 4.5-7 micrometers per hour) and very low defectivity. This single-pass slurry yields surface finishes of 0.7 angstroms. With a total usable area percentage of 99%, it does not compromise surface quality for speed and is an ideal choice for semiconductor CMP.

We often hear about the environmental benefits of electric vehicles (EVs) and appreciate their modern features. But what lies behind the seamless driving experience drawing consumers to purchase EVs?

While vehicles today showcase a range of technological advancement driven by sensors, EVs heavily rely on sensors to reduce greenhouse gas emissions and provide a luxury experience.

A closer look at EV sensors

EV sensors require capacitors to store energy passively until it is released on demand, ensuring a responsive power source for the intricate functionalities of EV systems.

A capacitor is composed of dielectric material sandwiched between two conductive plates. The dielectric material is an insulator that enhances capacitance and prevents the free flow of charges, ensuring that the stored energy remains stable and controlled. This neutralization enables efficient energy storage and plays a vital role in successful capacitor operation.

The emergence of IR reflective windshields

In response to the call for greener mobility, the automotive industry has embraced IR reflective windshields as an innovative solution to improve energy efficiency, enhance passenger comfort and comply with environmental regulations. These windshields are designed to reflect a substantial portion of IR radiation from the sun, significantly reducing the amount of heat entering the vehicle’s interior. As a result, the cabin remains cooler, reducing the need for air conditioning during hot summer days, and ultimately leading to fuel savings and lower carbon emissions.

“Our team draws on decades of experience producing silver pastes and additional high-performing products used to enhance automotive applications,” said Andre Noppe, vice president, glass coatings. “We work hand-in-hand with glass manufacturers to provide innovative solutions that help OEM’s achieve design, safety and sustainability goals.”

Innovation drives environmentally friendly transportation

IR reflective windshields offer many energy-efficient transportation benefits.

• Energy savings: By reducing the need for air conditioning, IR reflective windshields contribute to improved fuel efficiency, making vehicles more economical to run.
• Environmental sustainability: Lower fuel consumption results in reduced greenhouse gas emissions, helping combat climate change and promote a greener future.
• Enhanced comfort: IR reflective windshields maintain a cooler interior temperature, offering a more enjoyable driving experience, especially during scorching summers.

Silver pastes play a crucial role

At the heart of IR reflective windshields lies a critical component – silver pastes. Renowned for its exceptional electrical conductivity and high reflectivity in the IR spectrum, silver is the ideal choice for these specialized coatings. Silver pastes are formulated with silver particles suspended in a liquid medium, ensuring optimal adhesion to the windshield’s glass surface.

During the manufacturing process, the silver paste is applied to the windshield using a screen-printing technique. Once applied, the windshield undergoes a drying and firing process in a high-temperature furnace. This process fuses the silver particles, creating a continuous, conductive metallic layer that connects with the coating of the windshield (called bus bars). The coating is then connected to the vehicle’s electric system through the support of the silver bus bars.

High-performing products with multifaceted benefits

Vibrantz has been instrumental in the development of conductive silver pastes for automotive glass, driven by evolving market demands like modern car designs, complex glass shapes, light-weighting for fuel efficiency and end-of-life vehicle regulations.

Compared to alternative materials like metal copper stripes, printed silver is gaining popularity due to its lighter weight and increased durability. Silver pastes can be applied in thin, uniform layers and are generally more resistant to corrosion, which can be an essential consideration for long-term windshield durability.

Additionally, printed silver pastes enhance sensors for track control, rain detection, distance control and other significant safety features. They enable defogging and defrosting in this crucial area for passengers to see clearly.

While energy-efficient transportation will continue to be a top priority for both manufacturers and consumers, more and more vehicles will be equipped with energy-saving technologies that help mitigate environmental impact while lowering the operating costs for drivers.
