The current disclosure describes techniques for managing vertical alignment or overlay in semiconductor manufacturing using machine learning. Alignments of interconnection features in a fan-out WLP process are evaluated and managed through the disclosed techniques. Big data and neural networks system are used to correlate the overlay error source factors with overlay metrology categories. The overlay error source factors include tool related overlay source factors, wafer or die related overlay source factors and processing context related overlay error source factors.

Improved systems and methods for operating moveable architectural elements (e.g., furniture) are described. The system can include improved features implemented throughout various elements, including hardware elements, controller elements, and/or software elements. As one example, the system can feature the ability to map a characteristic load profile across a particular length of actuation and, if during operation a measured load exceeds the profile, adjust (e.g., stop) the system's motion. The system can also advantageously map its current draw to increase energy efficiency. In addition, the system can include a positioning system that enables it to automatically determine its position upon start up and during operation. In some implementations, the system includes multiple moveable elements (e.g., furniture items). In some cases, power is distributed to the moveable element(s) using a moveable power distribution module. Many other improvements and features are contemplated and described.

A contactless monitoring system detects operating performance of movers in an independent cart system. A contactless sensor is provided on an actuator to automatically track a mover as it travels along the track. The sensor includes a transmitter configured to transmit a signal and a receiver configured to receive the signal after it is reflected off the mover. The actuator may be configured to mover the sensor in a single axis or in multiple axes of motion. As a mover travels along the track, the sensor transmits a signal towards the mover and detects the signal after it has been reflected off the mover. A controller may synchronize motion of the actuator with motion of the mover, such that the sensor may continually transmit the signal off the mover for at least a portion of the travel by the mover along the track.

A gantry drive system includes: a first motor configured to drive a driving object along a first axis; a second motor configured to drive the driving object along a second axis parallel with the first axis; and a motor control system configured to control the first and second motors. The motor control system includes a mode switch that performs a switching between a first control mode in which a position of the driving object on each of the first and second axes is individually controlled while reducing an inter-axis positional deviation between the first and second axes, and a second control mode in which a rotational state of the driving object is controlled while controlling a position of the driving object, based on detected positions of the driving object on the first and second axes.

A method and a device are provided for simplifying a flow-hole screw process, in which the difference between a process parameter and its smoothed value is employed as a criterion for changing said process parameter or another process parameter in order in particular to be able to determine the changeover point between hole forming and thread forming.
