Patent number: 5800619Abstract: A substantially planar coil of a vacuum plasma processor has plural turns for exciting gas in the processor to a plasma state in response to r.f. coil energization. The coil is located outside the processor and surrounded by a shield tending to cause magnetic flux coupled from peripheral portions of the coil to the gas to be less than magnetic flux coupled from interior portions of the coil to the gas. The coil is arranged so magnetic flux derived from a center portion of an area circumscribed by the coil is less than the magnetic flux derived from all other areas circumscribed by the coil. The magnetic flux is such that the density of the plasma in the processor on a processed substrate is relatively uniform even though the coil exhibits transmission line properties so there are substantial peak-to-peak current variations along the length of the coil.Type: GrantFiled: June 10, 1996Date of Patent: September 1, 1998Assignee: Lam Research CorporationInventors: John Patrick Holland, Michael S.

Patent number: 5797033Abstract: A method and arrangement for receiving data in a direct memory access (DMA) controller and storing the received data in a host memory in a computer system determines the size of the packets of data to be transferred. The host memory is subdivided into large memory areas for storing large packets of data and small memory areas for storing small packets of data. A packet size determiner determines whether the packet of data to be transferred is a large packet of data or a small packet of data and provides a signal to the DMA controller. In response to this signal, the DMA controller selects a large memory area of the host memory for storing the data when the received data is determined to be a large packet of data and selects a small memory area of the host memory for storing the data when the received data is determined to be a small packet of data.Type: GrantFiled: March 31, 1995Date of Patent: August 18, 1998Assignee: Cirrus Logic, Inc.Inventor: Peter Ecclesine
