20140141541 | LOADING PORT, SYSTEM FOR ETCHING AND CLEANING WAFERS AND METHOD OF USE - A loading port includes a housing and a plurality of stations defined in the housing configured to receive a front opening universal pod (FOUP). The loading port further includes a connector configured to receive an inert gas. At least one of the plurality of stations is configured to deliver the inert gas to the FOUP to purge an interior of the FOUP of moisture. A system including the loading port and a method of using the system are also described. | 05-22-2014 |
20150064928 | PHOTORESIST REMOVAL - Among other things, one or more systems and techniques for removing a photoresist from a semiconductor wafer are provided. The photoresist is formed over the semiconductor wafer for patterning or material deposition. Once completed, the photoresist is removed in a manner that mitigates damage to the semiconductor wafer or structures formed thereon. In an embodiment, trioxygen liquid is supplied to the photoresist. The trioxygen liquid is activated using an activator, such as an ultraviolet activator or a hydrogen peroxide activator, to create activated trioxygen liquid used to remove the photoresist. In an embodiment, the activation of the trioxygen liquid results in free radicals that aid in removing the photoresist. In an embodiment, an initial photoresist strip, such as using a sulfuric acid hydrogen peroxide mixture, is performed to remove a first portion of the photoresist, and the activated trioxygen liquid is used to remove a second portion of the photoresist. | 03-05-2015 |

20150069147 | SPRAY GUN WITH SIDE-MOUNTED FAN CONTROL - A paint spray gun for use in association with a HVLP turbine blower and an attachable paint container divides input air flow into two horizontally adjacent channels. Air flow through one channel remains open whereas air flow through the second channel may be varied by a side air controller such that when air flow is cut off from the second channel, the paint mixture is sprayed in a substantially circular shape whereas when air flows through the second channel the paint mixture is sprayed in a substantially fan shape. | 03-12-2015 |

20130076312 | CHARGING CURRENT CONTROL METHOD AND CHARGING SYSTEM - A charging method and a charging system are introduced for controlling a charging current by a PWM method. A charging IC is controlled to supply the charging current to a battery, and a control unit is used to generate a PWM signal with a duty cycle, and a filter unit is used to convert the PWM signal into a voltage signal to be supplied to the charging IC, and the control unit determines whether a current of a battery detected by the battery status detection unit reaches a regular current, so that a PWM signal with a duty cycle greater than the previous duty cycle by a default increased cycle is provided if the detected current has not reached the regular current. Thus, the feature of the PWM signal is used to set the charging current according to the capacity of the battery automatically. | 03-28-2013 |
