New Lithographic Process for Growing Semiconductor Crystals

25.09.2000

Leading manufacturers of computer chips - Intel, AMD and Motorola, together with the Virtual National Laboratory (USA) are developing a new lithographic process used in the growth of semiconductor crystals.

The new lithographic process uses extreme ultraviolet wavelengths to produce elements with a transverse dimension of less than 0,1 microns on a semiconductor chip by placing more transistors on a single chip. According to the developers, the new lithography technology will make it possible to create 100 times more powerful processors and 100 times more capacious memory chips than is possible with modern semiconductor growing technologies.

The first processors created using this technology will operate at a clock speed of about 10 GHz (currently the fastest commercial chips from Intel and AMD are clocked at 1 GHz).

It is planned that commercial production using ultraviolet lithography technology will begin in 2005.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

STM32G031Y8Y - 64 MHz controller with SMD component dimensions 09.12.2019

ST Microelectronics has introduced a new general-purpose microcontrollers - STM32G031Y8Y. They belong to the full-featured line of the STM32G0 family.

The main distinguishing feature of this model is the smallest dimensions among all ST microcontrollers - 1,86 x 2,14 mm. At the same time, these products are among the highest performing microcontrollers based on the cortex-M0 + core and have all the key advantages of their family: low power consumption, high level of integration, improved software protection, the ability to provide power through only two outputs, an improved internal RC oscillator and low price.

For cases where the use of the WLCSP is not possible due to the nature of its soldering, ST has released small-sized models in the SO8 package, for example, the STM32G031J6, also available for order.

Key Features:

Clock speed: 64 MHz (142 CoreMark);
Flash 64 kB, RAM 8 kB;
SPI, I2C, USART/UART, LPUART;
Timer at 128 MHz, LPTIM;
DMA, DMAMUX;
12-bit ADC 2,5 MSPS;
Supply voltage: 7...3,6 V;
Operating temperature range -40...85/125°С;
Chassis: WLCSP18.
