Title: Charge pump for a semiconductor substrate
Inventor: PROEBSTING ROBERT J
IPC: G11C11/40
Filed: 1997-07-26
Granted: 1999-06-21
Abstract: A low voltage current source generates low voltage signals for powering a variable frequency oscillator. The low voltage signals are at a slightly higher voltage until a negative substrate bias is achieved. The oscillator operates a low frequency when charge pumping is in fact needed or when charge pumping will most likely be needed. The variable frequency oscillator controls a timing signal generator which generates the timing signals used to control the overall operation of the charge pump system. Voltage translation circuitry translates the low voltage current source signals into higher voltage signals which are used to translate the substrate voltage from its negative value to a positive value so that the substrate voltage may be compared to a reference voltage using a conventional comparator. When the substrate voltage is above the desired level, the comparator generates a pump activating signals to a pump signal generator which, in turn, generates the necessary signal to cause the charge pump to operate.

Title: Polishing tool and method for operating a polishing tool
Inventor: TZENG HUEY-MING
IPC: B24B37/04
Filed: 1998-11-04
Granted: 2000-03-01
Abstract: An in-situ sensor measures polishing pads during chemical mechanical polishing. >From the measurement, polishing pads can be identified as worn out or unevenly worn and replaced. Scheduling maintenance according to current measurements, rather than according to statistical predictions, minimizes down time for maintenance and still prevents use of worn out or unevenly worn polishing pads. Alternatively, a tool is reconfigured according to the polishing pad measurements. Reconfiguring the tool can prolong pad life and improve polishing performance. One embodiment of the invention includes a non-contact sensor such as a laser sensor that directs an incident beam at a target area and determines a distance to a reflection point by triangulation of incident and reflected beams. As polishing pads wear, distances to the reflection points increase. Movement of the polishing pads and the sensor during polishing causes the in-situ sensor to measure portions of the polishing pads that are along a zigzag trajectory. When the frequency of the sensor's motion is a multiple of the frequency of revolution of the polishing pads, the sensor retraces the same trajectory after one or more revolutions of the polishing pads. Thus, pad thickness or wear at the same set of points can be compared from one tracing of the trajectory to the next.

Title: Method for judging the steel wire position of a steel wire rim
Inventor: CHEN CHIAU-LING
IPC: B60B1/04
Filed: 1999-03-24
Granted: 2001-07-11
Abstract: Disclosed is a method for judging whether the steel wire position of a steel wire rim is at the first side or the second side of the rim. The device using such method can accurately drive a robot for adjusting tightness of the copper head according to the execution result of the method. The judgment method is to detect the steel wire of a rotating rim with a photoelectric device. There is a signal output from the photoelectric device when each steel wire crosses the light source projection path of the photoelectric device. The time interval between signals may be long or short because the time for a steel wire to pass by the photoelectric device can be different. The logical relation from analyzing the time intervals can be used to determine if the detected steel wire is located at the first side or the second side of the rim, which information can be provided to the device for further use.
