  • Publication number: 20180138020
    Abstract: Provided herein are approaches for dynamically modifying plasma volume in an ion source chamber by positioning an end plate and radio frequency (RF) antenna at a selected axial location. In one approach, an ion source includes a plasma chamber having a longitudinal axis extending between a first end wall and a second end wall, and an RF antenna adjacent a plasma within the plasma chamber, wherein the RF antenna is configured to provide RF energy to the plasma. The ion source may further include an end plate disposed within the plasma chamber, adjacent the first end wall, the end plate actuated along the longitudinal axis between a first position and a second position to adjust a volume of the plasma. By providing an actuable end plate and RF antenna, plasma characteristics may be dynamically controlled to affect ion source characteristics, such as composition of ion species, including metastable neutrals.

  • Patent number: 9966117
    Abstract: Disclosed are a latch circuit receiving a negative output of a next latch stage circuit as a feedback input, a double data rate (DDR) ring counter based on the latch circuit to perform DDR counting of pulse periods and reduce the number of toggles, a hybrid counting device counting lower-bit portion by using the latch-based DDR ring counter and upper-bit portion by using a binary counter, and an analog-to-digital converting device and a CMOS image sensor employing the hybrid counting device. A double data rate ring counter may include a plurality of latches coupled in a form of a ring. The plurality of latches may include positive-edge-triggered latches and negative-edge-triggered latches arranged alternately. A current latch stage receives an output of a preceding latch stage to shift to a next latch stage according to a counter clock, receives an output of the next latch stage to check a data shift to the next latch stage, and falls to a low level if the data shift is checked.
