Changxin Science & Technology Begins Mass Production of 5th-Gen Platform

Changxin Science & Technology (Longxin Technology · 688825) has been reported to have officially launched mass production of its 5th-generation process platform. Products based on this platform, including 24GB LPDDR5X memory chips, are now being supplied to leading smartphones. PANews cited a report stating that Changxin Science & Technology announced the official mass production of its 5th-generation technology platform at the World Manufacturing Conference on July 20.

The 5th-generation platform features a half pitch of 11.95 nanometers in the memory array active area, a capacitor aspect ratio of 45:1, and reduced core power area height to 6762 nanometers. PANews also reported that under the same conditions, wafer yield has increased by over 50% compared to previous generations.

However, Changxin Science & Technology noted in its Q2 2026 report that the 5th-generation process technology platform is currently undergoing customer certification, and at a July investor meeting, it stated the platform was still in the research phase. This raises questions about whether the mass production announcement has been officially confirmed.
