Title: Integration of remote plasma generator with semiconductor processing chamber
Inventor: JANAKIRAMAN KARTHIK
IPC: C23C16/509
Filed: 2001-04-27
Granted: 2002-06-21
Abstract: A compact, self-contained remote plasma generator is mounted on the lid of a semiconductor processing chamber to form an integrated substrate processing system. The remote plasma generator is activated in a clean operation to generate cleaning plasma species to provide better cleaning of the chamber and lower perfluorocarbon emissions than in situ plasma clean processes. A three-way valve is adjustable to control gas flow to the chamber. During the clean operation, the three-way valve directs a cleaning plasma precursor from a first gas line to the remote plasma generator to generate cleaning plasma species which are flowed to the chamber for cleaning deposits therein. During a deposition process, the three-way valve directs a first process gas from the first gas line to the chamber, bypassing the remote plasma generator. The first process gas is typically mixed with a second process gas supplied from a second gas line in a mixing device prior to entering the chamber for depositing a layer on a substrate disposed therein.

Title: Time-to-digital converter
Inventor: WEST BURNELL G
IPC: H03K5/13
Filed: 2001-08-17
Granted: 2004-04-21
Abstract: A time-to-digital converter records the arrival times of successive signals-which are separated from one another by more than one period of a reference clock signal-by recording the number of nodes disposed within a plurality of fine delay paths-each coupled to a different one of a plurality of coarse delay stages in a first coarse delay path-through which the signals propagate. The delay across each fine delay path is substantially the same as the delay across a coarse delay stage in the coarse delay path. A phase detector maintains the clock signal and its delayed replica in phase by adjusting the delay through each of the coarse delay stages in a second coarse delay path. The time delay between the clock signal and its delayed replica is equal to one period of the clock signal. A plurality of registers store the voltages of the nodes within each of the fine delay paths and supply the stored results to a plurality of priority encoders for encoding the time priority with which the signals arrive at the nodes. A delay encoder determines the extent of the propagation of the successive signals through the nodes to thereby generate time-stamps representative of the arrival times of the signals.
