High-Performance 4H-SiC EUV Photodiode With Lateral p-n Junction Fabricated by Selective-Area Ion Implantation​


Abstract:
In this work, a 4H-SiC EUV photodiode (PD) with lateral p-n junction formed by selective-area ion implantation is investigated, in which grid-shaped p-type contact region is designed for enhancing effective EUV light absorption. The large area SiC PD with 9 mm diameter exhibits a low dark current density of ∼9 pA/cm2 and a high responsivity of 0.07 A/W at 13.5 nm under 5 V reverse bias. The detectivity of PD is further determined to be ∼5.9×1012 cmHz 0.5W−1 based on 1/f noise test. Two-dimensional photocurrent mapping of photosensitive area indicates that the non-uniformity of photo-responsivity at 13.5 nm is less than 0.67%. When tested by using a 266 nm pulse laser, the PD shows a fast rise time of ~4.3 ns in transient response measurement. The PD also exhibits low dark current, stable capacitance and responsivity at elevated temperatures up to 150 °C, suggesting that the detector has good potential for high-temperature operation.​

sounds like CR Micro Chengdu is a major supplier to CETC, AVIC, CASC & CASIC for avrious FPGA, MCUs, memory and logic chips

It says it's produce can cover UAV market

China's military electronics market expect to increase to 501B RMB by 2025
They are also one of the most competent suppliers of high speed ADC in China. They’ve just developed a 12G 12bit ADC in single channel.

Zhuo Shengwei: Demand in the RF front-end industry has improved, and the 6-inch filter production line is at full production​



According to Mams Consulting, Jiangsu Zhuosheng Microelectronics Co., Ltd. (referred to as: Zhuosheng Micro) recently held an investor relations event. The company’s chairman and general manager Xu Zhihan and other senior executives participated in the exchange. The details are as follows:
1. Briefly introduce the company’s operating performance in 2023 and the first quarter of 2024
In 2023, the radio frequency front-end industry experienced customer inventory backlog and shrinking demand in the early stage. Later, it was affected by factors such as improved inventory conditions, holiday consumption stimulation, and the continuous emergence of new Android phones. The company's operating performance improved significantly in the second half of the year.

In 2023, Zhuoshengwei achieved operating income of 4.378 billion yuan, a year-on-year increase of 19.05%; net profit attributable to shareholders of listed companies was 1.122 billion yuan, a year-on-year increase of 4.95%. The impact of share-based payment expenses on net profit in 2023 totals 33.5 million yuan. The overall gross profit margin in 2023 was 46.45%, a year-on-year decrease of 6.46%, mainly due to the construction of Xinzhuo production lines, changes in product structure, and market competition for homogeneous products. At the same time, benefiting from the large-scale mass production of self-built production lines, Zhuosheng Micro's demand for high-end modules has steadily increased, and the sales proportion of module products has increased from 30.42% in the previous year to 36.34% in 2023.

In the first quarter of 2024, Zhuosheng Micro achieved operating income of 1.19 billion yuan, a year-on-year increase of 67.16%; net profit attributable to the parent company was 198 million yuan, a year-on-year increase of 69.83%. The impact of share-based payment expenses on net profit in the first quarter totaled 12.99 million yuan. The gross profit margin was 42.77%, and the gross profit margin remained basically stable quarter-on-quarter.

In terms of self-built production lines, Zhuosheng Micro 's biggest gain in 2023 is the progress in filter products. The 6-inch filter production line has developed from basically zero shipments at the beginning of 2023 to full production at the end of the year. At the same time, the company launched The performance of high-end filter products can reach the level of BAW and FBAR in applications below sub-3GHz, and its market progress has exceeded the company's expectations. At the same time, the company's 12-inch IPD platform has officially entered the mass production stage. L-PAMiF, LFEM and other related module products integrating self-produced IPD filters have been verified by many clients and have been mass-produced and shipped. On the basis of building 12-inch wafer manufacturing capabilities, the company is committed to achieving differentiated layout and reflecting competitive advantages.

Suzhou Zhicheng Semiconductor Technology has patented a scrubber for immersion photoresist​

A kind of wafer glue removal and stripping equipment​

CN 117690833

Abstract​

The invention provides a wafer degumming and stripping equipment, which includes a frame, and a soaking device, a spray device and a cleaning device installed on the frame. The soaking device, the spray device and the cleaning device are all adapted to the first size wafer. For the soaking, spraying and cleaning steps of round and second-size wafers, the spray device and the cleaning device are both equipped with a main cavity and a driving assembly. The cleaning device also includes a cleaning and drying device; the cleaning nozzle and the drying nozzle are placed on the drive respectively. The first size wafer or the second size wafer on the disk surface is sprayed with cleaning chemicals and drying chemicals, and the swing arm is driven to drive the cleaning nozzle and drying nozzle to swing. The present invention is used to solve the problem in the prior art that the cleaning step of the wafer deglue stripping equipment does not have the effect of removing residual droplets on the wafer surface, thereby causing water marks on the wafer surface, and can be adapted to two sizes of wafers at the same time. The need for round debonding and stripping is effectively reduced, thereby effectively reducing the cost of producing wafers of different sizes.​

Accurate assessment or just cope?

“It is too early to identify the potential influence China would have on the HBM market. But we are skeptical about CXMT succeeding in developing the delicate technology required to produce HBM,” an industry official said under the condition of anonymity.

“CXMT has been saying it will master the production of advanced DRAM chips for the past decade, but it still struggles with conventional DRAMs. I believe it would be difficult for China to catch up to the HBM technology of current players in 4-5 years.”
