Data center I/O, AI accelerators; nanostructures split in half; automotive full-stack driverless vehicle platforms; SPM for 3D surface measurements.

popularity

Chip-to-chip and data center I/O drew investor interest in September, including support for several startups developing Compute Express Link (CXL) solutions. Elsewhere in the data center, several large rounds went to companies developing AI accelerators. And at the edge, startups are building unique ways to handle AI at very little power by initially processing data directly at the sensor.

On the manufacturing and test side, one startup is splitting nanostructures in half using atomic layer etching, while others are introducing e-beam inspection and scanning probe microscopy metrology equipment.

Here are some highlights from September funding rounds [find the full sortable table here].
