Wet-like plasma etching Researchers from Nagoya University and Hitachi developed a new etch method called wet-like plasma etching that combines the selectivity of wet etching with the controllability of dry etching. The researchers say the technique will make it possible to etch complex structures such as metal carbides consisting of titanium (Ti) and aluminum (Al), such as TiC or TiAlC, wh... » read more

Chip Industry’s Technical Paper Roundup: Mar. 28
By Linda Christensen - 28 Mar, 2023 - Comments: 0

New technical papers recently added to Semiconductor Engineering’s library: [table id=89 /] If you have research papers you are trying to promote, we will review them to see if they are a good fit for our global audience. At a minimum, papers need to be well researched and documented, relevant to the semiconductor ecosystem, and free of marketing bias. There is no cost involved for us p... » read more

Hot Trends In Semiconductor Thermal Management
By Karen Heyman - 17 Nov, 2022 - Comments: 1

Increasing thermal challenges, as the industry moves into 3D packaging and continues to scale digital logic, are pushing the limits of R&D. The basic physics of having too much heat trapped in too small a space is leading to tangible problems, like consumer products that are too hot to hold. Far worse, however, is the loss of power and reliability, as overheated DRAM has to continually r... » read more
