On October 28, 2020, led by Shenzhen Municipal Bureau of Industry and Information Technology and Shenzhen Futian District People's Government, hosted by OFweek Veken Network, a high-tech industry portal, and hosted by OFweek Veken Network Electronic Engineering "2020 China International Integrated Circuit Industry Innovation and Development" Gao Feng (60) mentioned SOTB process many times in his speech report. SOTB process technology using new transistor technology is a new type of transistor technology using SOI (Silicon on Insulator). Experts said that, as a monopoly process of Renaissance Electronics, SOTB can usually reduce the power consumption during active and sleep time, which is difficult to balance, to the limit, while also supporting a hybrid structure of SOTB and Bulk on one chip.

An extremely thin insulating layer (cell: buriedoxide) is formed under the thin silicon layer on the wafer substrate. By preventing impurities from mixing into the silicon layer, stable low-voltage operation can be achieved, with better energy efficiency and better computing performance. In addition, by controlling the potential of the silicon substrate under the BOX layer during standby (reverse bias control), leakage current can be reduced and standby energy can be reduced. Since the chip of SOTB adopts a thin BOX structure, it is easy to remove the BOX, so that SOTB transistors and Bulk CMOS transistors can be formed on the same chip.

This allows the use of IP, I/O ports, charge pumps, various analog IP, etc. from existing Bulk products. The product family of Hongzeweiye Technology adopts SOT BTM (SIlicononthinburiedoxide thin oxide embedded silicon) process and is based on Arm Cortex-M0 core. Experts in sensor control specially introduced RE01. RE01 has very low power consumption during operation and standby. 1.62V can run up to 64MHz, ULP-CP score of 705 is EEMBC certified. In environments with only a small amount of current, long battery life and high-speed operation can be achieved, providing values previously unachievable. So, how to be environmentally friendly? Experts said that Hongze Weiye Technology reduces power consumption by supporting three power saving functions: power mode, low power mode and power control mode.

1. Reduce power consumption by cutting off unnecessary power.

2. Stop the clock and perform the necessary minimal functions, thereby reducing power consumption.

3. By controlling the internal LDO in power control mode, the effective current can be greatly reduced by using a high-efficiency external DCDC. With the deepening of the concept of sustainable development, environmental protection has also become an important part of the development of technology enterprises that cannot be ignored. How to protect the environment through the development of science and technology is worthy of in-depth exploration by all science and technology enterprises. The value of science and technology is to make everything possible. As a leading and reliable supplier of smart chip solutions for furniture, Hongzeweiye Technology will continue to strive to create a more comfortable and better life for human beings.
