This socket was short-lived, as it became apparent that its electrical design proved inadequate for raising clock speed beyond 2.0 GHz. Intel produced chips using this socket for less than a year, from November 2000 to August 2001.
It was replaced by Socket 478 in 2001, which being microPGA was cheaper to manufacture.
