A method of manufacturing a semiconductor device includes forming a lower structure including a plurality of transistors, forming a conductive layer on the lower structure, forming first preliminary pad mask patterns and wiring mask patterns on the conductive layer, forming pad mask patterns by patterning the first preliminary pad mask patterns while protecting the wiring mask patterns, and etching the conductive layer using the pad mask patterns and the wiring mask patterns as an etching mask to form pad patterns and wiring patterns.

Methods of manufacturing semiconductor device

The present invention relates to a mobile terminal and a control method thereof. The mobile terminal displays a plurality of figures arranged in a first composition on a touch screen when a specific mode is locked, rearranges the plurality of figures in a second composition different from the first composition upon receiving a specific input, and determines whether to unlock the specific mode on the basis of a pattern which is input using the plurality of figures arranged in the first or second composition.

Mobile terminal and control method thereof

A robot cleaner including a driving unit configured to move the robot cleaner; a charging unit disposed on an upper surface of the robot cleaner, and configured to wirelessly charge a mobile terminal; and a control unit configured to control the driving unit to move the robot cleaner to a position of the mobile terminal corresponding to a sensed preset signal, control the robot cleaner to execute a wireless charging of the mobile terminal placed on the charging unit according to a charging command, and output a feedback signal when the wireless charging of the mobile terminal is completed.
