Abstract: A semiconductor may include an active region, an epitaxial source/drain formed in and extending above the active region, and a first dielectric layer formed over a portion of the active region. The semiconductor may include a first metal gate and a second metal gate formed in the first dielectric layer, a second dielectric layer formed over the first dielectric layer and the second metal gate, and a titanium layer, without an intervening fluorine residual layer, formed on the metal gate and the epitaxial source/drain. The semiconductor may include a first metal layer formed on top of the titanium on the first metal gate, a second metal layer formed on top of the titanium layer on the epitaxial source/drain, and a third dielectric layer formed on the second dielectric layer. The semiconductor may include first and second vias formed in the third dielectric layer.

Abstract: A padlock and cabinet lock fingerprint lockset includes a resetting component, a fingerprint setting switch and a PCBA control module. The fingerprint setting switch is connected to the signal input end of PCBA control module. The fingerprint module has a fingerprint resetting module and a fingerprint initial value setting module which are connected to the signal output end of PCBA control module respectively. The PCBA control module can activate the fingerprint resetting module and fingerprint initial value setting module when the fingerprint setting switch is activated. When the padlock or bolt is pressed down to touch the fingerprint setting switch, the fingerprint setting switch makes the PCBA control module generate a loop by line connection, so as to implement fingerprint initial value setting or fingerprint resetting. The probability of misoperation is low, preventing the failure in opening the fingerprint lock when a child mishandles the fingerprint lock.

Abstract: An interactive electronic whiteboard with video communication function is disclosed, including an electronic whiteboard body, a master control board is embedded in the framework of the electronic whiteboard body, computer or tablet PC or mobile phone connected to electronic whiteboard body, as well as a camera mounted in the upper frame of framework of the electronic whiteboard body. The camera has an optical lens, an optical sensor and a control transmission chip connected in turn. The optical sensor is connected to computer or tablet PC or mobile phone via control transmission chip. The camera provides video communication function, solving the problem in the present electronic whiteboard which cannot implement visual communication.
