  • Publication number: 20150054780
    Abstract: A touch pad outputs a detection signal indicating a coordinate corresponding to a contact state where a finger is in contact with the coordinate detecting unit, and a detection signal indicating a coordinate corresponding to a proximity state where the finger is in proximity to, without contact with, the coordinate detecting unit. An operation input device detects, based on the detection signals, a contact region in which the finger is in contact with the coordinate detecting unit, and a proximity region in which the finger is in proximity to, without contact with, the coordinate detecting unit. Then, the operation input device determines a pointed coordinate based on the contact region detected and the proximity region detected.

  • Publication number: 20150054535
    Abstract: Provided is a probing testing apparatus of a semiconductor wafer with excellent repeatability and ease of maintenance. A gas injection port supplying oxidation preventing gas for preventing oxidation of a probe needle is provided on an inner side wall of a shielding structure mounted to a wafer probing stage within a prober so as to surround an outer side surface of a wafer. By allowing an oxidation preventing gas to flow to a part of the probe needle that is brought into contact with the wafer through an outer circumference and an upper surface of the wafer, a gas atmosphere around the probe needle is maintained by the oxidation preventing gas. With this configuration, since it is unnecessary to provide a spray nozzle above a probe card, position adjustment of the nozzle accompanying replacement of the probe card is not needed. Further, regardless of a configuration of the probe card, it is possible to blow the oxidation preventing gas even in a vertical-type probe card.
