Abstract: An ion collector includes a plurality of segments and a plurality of integrators. The plurality of segments are physically separated from one another and spaced around a substrate support. Each of the segments includes a conductive element that is designed to conduct a current based on ions received from a plasma. Each of the plurality of integrators is coupled to a corresponding conductive element. Each of the plurality of integrators is designed to determine an ion distribution for a corresponding conductive element based, at least in part, on the current conducted at the corresponding conductive element. An example benefit of this embodiment includes the ability to determine how uniform the ion distribution is across a wafer being processed by the plasma.

Abstract: A catalytic seeding control method is disclosed. A catalytic metal film is deposited on a substrate with a nonwettable inclined surface. The catalytic metal film is then melted to form metal droplets. The metal droplets roll along the nonwettable inclined surface and aggregate to form a singular catalytic seed on the bottom of the nonwettable inclined surface. Then, the location of the singular catalytic seed is precisely controlled. Also, the size of the catalytic seed is controlled by adjusting the size of the inclined surface and the thickness of the catalytic metal layer to grow a one-dimensional structure with specific localization and single well-aligned manipulated size. The structure is utilized for the integrated microelectronic device fabrication.

Abstract: A golf club head comprises a head portion and a neck portion which has a cross section with a flexible section. The longitudinal direction of the cross section of the flexible section and the heel-toe direction of the golf club head form an angle ranging between zero and 90 degrees. In light of the short axial direction of the cross section of the flexible section having a better flexibility, when the golf club head hits a ball, the flexibility in the left front direction or the right front direction is better than other direction. The ball has a tendency to travel along the predetermined side so as to correct the golfer's habit to hit the ball to travel in other side.
