The present disclosure relates to a method of deriving quality improvement requirements. The method according to some embodiments may include receiving a plurality of evaluation information for a first product from an evaluation information database, inputting the plurality of evaluation information into a key phrase extraction model and determining key phrases for the plurality of evaluation information based on an output of the key phrase extraction model, grouping some of the key phrases for the plurality of evaluation information into multiple groups and storing information on each of the multiple groups in a memory, ranking the key phrases included in each of the multiple groups and storing information associated with the ranks of the key phrases included in each of the multiple groups in the memory and determining top n key phrases from each of the multiple groups as quality improvement requirements.

Method of deriving quality improvement requirements

Motor position learning method and apparatus for an electric shift-by-wire system are proposed. The method includes setting, as a first reference position, a motor position at a time point when shift is completed; driving the motor in opposite directions on the basis of the first reference position; measuring a rotation amount of the motor and a driving current flowing through the motor while the motor is driven in opposite directions; and calculating a rotation amount of the motor at a point where the driving current of the motor becomes minimum, and setting, as a second reference position, a position resulting after the motor rotates further by the calculated rotation amount from the first reference position.

An RF sensing apparatus configured for use with a plasma processing chamber includes a penetration unit opened in an up/down direction, a main return path unit surrounding all or a portion of the penetration unit, and a secondary return path unit located between the penetration unit and the main return path unit, spaced apart from the main return path unit, and surrounding all or a portion of the penetration unit. The main return path unit and the secondary return path unit include a path through which a current flows in one of the up/down directions.

A semiconductor package is presented which has a suitable structure for effectively shielding electromagnetic wave interference (EMI) in a cavity area to which a semiconductor chip is attached. The semiconductor package is assembled such that a lower substrate to which the semiconductor chip is attached is adhered to an EMI shielding & electric I/O body having various types of EMI shielding & electric I/O metal patterns by soldering. Further, the EMI shielding & electric I/O body is adhered to an upper substrate by soldering thereby simplifying assembling of the semiconductor package.
