Develop a high-yield 110nm new principle high-yield lithography machine based on the principle of holographic lithography, break through the key technologies of core components, subsystems and complete machines, break foreign embargoes, fill domestic gaps, and form core competitive advantages such as cost-effectiveness. The funds applied for are intended to be used for equipment costs, material costs, and outsourcing processing costs in the development of new principle high-yield lithography machines. Relying on the research and development team of the Precision Instrument Engineering Research Institute of Harbin University of Technology (led by academicians and 240 people with doctoral degrees), we have mastered all the core technologies of this lithography machine and have started the research and development of this project since October 2023. This project also includes the National Lithography Machine Industry Metrology and Testing Center approved by the General Administration of Quality Supervision, Inspection and Quarantine in January 2024 to support the research and development of the complete lithography machine of this project.

Hua Hong Microelectronics' patent for "SGT device manufacturing method" is published

Shanghai Huahong Grace Semiconductor Manufacturing Co., Ltd.'s patent was announced, the application publication date is August 9, 2024, and the application publication number is CN118471814A.



The present application relates to the field of semiconductor integrated circuit manufacturing technology, and specifically to a method for manufacturing an SGT device. The method comprises the following steps: providing a semiconductor layer, etching the semiconductor layer to form a deep trench structure; manufacturing a shielding gate structure located at the bottom of the deep trench structure and a first oxide layer isolating the shielding gate structure from the semiconductor layer in the deep trench structure, so that a filling space is formed at the top of the deep trench structure; forming a gate oxide layer on the side of the first filling space and on the upper surface of the semiconductor layer; depositing control gate polysilicon, so that the control gate polysilicon fills the filling space with the gate oxide layer; etching back the gate oxide layer and the control gate polysilicon through a selective dry etching process, so that the gate oxide layer is etched to remove the first target back etching thickness, and the control gate polysilicon is etched to remove the second target back etching thickness; depositing an interlayer dielectric layer, and the interlayer dielectric layer is filled with the top of the deep trench structure and then wrapped on the semiconductor layer.

Yunhan Xingchi completed tens of millions of angel round financing and is a full-solid-state deep ultraviolet laser manufacturer (DUV) KrF and ArF​

According to Zhongguancun Collaborative Fund, Beijing Yunhan Xingchi Laser Technology Co., Ltd. recently announced that it has completed tens of millions of angel round financing, led by Zhongguancun Capital and followed by Shunxi Fund. This round of financing will be mainly used for capacity expansion, organizational upgrading and new product research and development.

Founded in November 2023, Yunhan Xingchi is an all-solid-state deep ultraviolet laser manufacturer that focuses on laser research and development in the chip semiconductor field. Its products adopt an all-solid-state technology route, a compact structure design concept, simple peripheral interfaces, and remote diagnostic functions. Its founding team has worked together for many years and has been engaged in laser development since 2008. It has always adhered to the all-solid-state technology route and has developed many laser products that have been recognized by the market and have a good reputation. Based on more than ten years of industry accumulation, the core team has strong comprehensive technical capabilities in optics, machinery, electricity, computing, and control.

Yunhan Xingchi's products include three products in two series: all-solid-state nanosecond green lasers and all-solid-state quasi-continuous ultraviolet picosecond lasers, which mainly serve the wafer annealing and measurement scenarios of chip semiconductors . At present, it has obtained batch orders from many leading customers in the industry and has achieved stable delivery .

Ren Peng, chairman of Shunxi Fund, pointed out that Yunhan Xingchi is an excellent startup company in the field of core components of semiconductor equipment. The laser products it develops are core components for measuring equipment and annealing equipment in semiconductor front-end manufacturing equipment. They are core consumables that directly affect the yield of wafer manufacturing and have great development potential.

A bit OT, but this just goes to show that however impressive the scale of the shipyards on Changxing Island, their economic worth pales beside that of semiconductors.

Looks like 紫光同芯 has unveiled THA6412 auto MCU. ASIL-D compliant and also achieved Evita-Full.

Uses ARM Cortex R52 and operates at 400 MHz.

This is better than the 1st gen auto MCU that they had before
No idea who their clients are.

Every time I see RISC-V or Arm, I wish it was LingxiISA or LoongArch instead....
