Chemical mechanical planarization (CMP) technology has been around for a long time. In addition to the semiconductor industry, CMP has applications in data storage, polishing the rigid disks and magnetic heads of hard-disk drives.

Those interested in learning about developments in CMP for hard drives and integrated circuits would do well to attend the CMP Technical and Market Trends session on Thursday, July 16, at 11 a.m. in the TechXPOT North area of Moscone Center’s North Hall. Representatives of Intel, HGST, Entegris, TDK, and other companies will be speaking.

While 450-millimeter wafers haven’t been much in the news this year, Thursday’s session will include a presentation by the Global 450 Consortium, with speakers from the College of Nanoscale Science + Engineering (CNSE) and SEMATECH.

CNSE is part of the SUNY Polytechnic Institute in Albany, N.Y., which also contains the Chemical Mechanical Planarization Center, a joint program with SEMATECH. Mitsubishi Chemical joined the program this spring.

While CMP is still used for its traditional polishing applications for interlayer dielectrics, it’s also finding employment in more advanced applications, such as bulk oxide polishing, shallow trench isolation, “stop on poly” isolation, and polishing of various dielectrics in advanced transistor designs.
