Intermolecular lands $20M to improve semiconductor manufacture

San Jose, Calif.-based Intermolecular, a company that streamlines the manufacture of semiconductor components, has raised $20 million of an expected $30 million fourth round of funding from CMEA Ventures, Redpoint Ventures, Symyx Technologies and US Venture Partners.

The company recently announced a collaboration with chipmaker AMD for molecular self-assembly technology — in which molecules would arrange themselves without outside guidance to produce an intended effect. Many of its operations are devoted to research and development. Before this tranche, it had raised $38.5 million.
