Methods and systems for adaptively controlling process parameters in semiconductor manufacturing equipment. An embodiment provides for gain scheduling of PID controllers across recipe steps. One embodiment provides a method for controlling a chuck temperature during a semiconductor manufacturing process, the method employing a first set of proportional-integral-derivative (PID) values in a PID controller to control the chuck temperature at a first setpoint in a first step of a process recipe and employing a second set of PID values in the PID controller to control the chuck temperature at a second setpoint, different than the first setpoint, in a second step of the process recipe. The methods and systems provide reduced controller response times where process parameter setpoint between steps of a process recipe span a wide range.

Methods for processing a substrate are provided herein. In some embodiments, a method of etching a dielectric layer includes generating a plasma by pulsing a first RF source signal having a first duty cycle; applying a second RF bias signal having a second duty cycle to the plasma; applying a third RF bias signal having a third duty cycle to the plasma, wherein the first, second, and third signals are synchronized; adjusting a phase variance between the first RF source signal and at least one of the second or third RF bias signals to control at least one of plasma ion density non-uniformity in the plasma or charge build-up on the dielectric layer; and etching the dielectric layer with the plasma.

Connectors for interconnecting rods, fixed to vertebrae and other bones of a subject include a body portion and two recesses or pockets for receiving the rods. These connectors are generally able to be secured to the rods by a tightening a fastener or retaining member from above the spine, which can facilitate the procedure for the surgeon. The connectors can include rotatable or stationary pockets, mating members that pivot and/or translate within the coronal plane of the subject to adjust to the positions of the rods, and extension shafts that pivot to adjust for rod angle.

Bone hooks for use in a spinal fixation system are provided. A device of the invention includes a head portion that can engage a spinal rod of a spinal fixation system, and a hook portion that can be positioned on and/or around a portion of a vertebra. In one embodiment of the invention, the hook portion is adjustably movable with respect to the body portion. In another embodiment, the hook portion includes an auxiliary bone engaging element that can contact a vertebra positioned with a bone receiving region of the hook portion. The auxiliary bone engaging element according to the present invention is particularly useful for maintaining the desired position of the device both during and after the implantation of a spinal fixation system.

A diagnostic catheter having both a guidewire lumen and at least one contrast lumen is disclosed. In one embodiment, the contrast lumens allow the user to deliver contrast to a target area within the patient without removing the guidewire. Preferably, a plurality of contrast exit ports are included along the length of the catheter body to evenly and consistently distribute contrast into the blood stream, thereby providing improved visualization during radioscopy.

Methods and systems for controlling temperatures in plasma processing chamber with reduced controller response times and increased stability. Temperature control is based at least in part on a feedforward control signal derived from a plasma power input into the processing chamber. A feedforward control signal compensating disturbances in the temperature attributable to the plasma power may be combined with a feedback control signal counteracting error between a measured and desired temperature.
