Patent ID: 8221098

Claim:
A radial turbomolecular pump apparatus, comprising: a stator disk positioned in a substantially radial direction, said stator disk comprising a plurality of stator microblades extending from said stator disk, said plurality of stator microblades arranged in concentric rings of blades and tilted towards said substantially radial direction; a rotor disk positioned between a driver and said stator disk in said substantially radial direction, said rotor disk comprising a plurality of rotor microblades, said plurality of rotor microblades arranged in concentric rings of blades and disposed between said concentric rings of said plurality of stator microblades and tilted towards said substantially radial direction; and at least one electrode arranged in concentric rings on a center portion of said driver and said stator disk, wherein a rotation of said rotor disk moves said plurality of rotor microblades tangentially relative to said plurality of stator microblades in order to facilitate a momentum transfer to gas molecules in a radial direction, thereby enabling a high compression ratio and pump speed at a chip-scale level.
