Title: Semiconductor device and preparation method thereof
Inventor: YANG CHENGXIN
IPC: H01L21/768
Filed: 2022-09-06
Abstract: This application provides a semiconductor device and a preparation method thereof. A second region of the semiconductor device has a TGV, and the semiconductor device includes a substrate, and an epitaxial layer, a first dielectric layer, a first metal layer, a second dielectric layer, a protective layer, and a second metal layer that are sequentially laminated on the substrate. The first metal layer is located in the first region, the second dielectric layer has through vias that penetrate through the second dielectric layer to connect the first metal layer and the protective layer, and a connecting material is filled in the through via to form a connecting piece. In addition, the TGV penetrates through the protective layer, the second dielectric layer, the first dielectric layer, and the epitaxial layer to the substrate. The second metal layer covers the protective layer and an inner wall of the TGV and is in contact with the substrate. The protective layer in the semiconductor device can cover the connecting piece, so that the connecting piece is not affected when a TGV process is performed, to ensure a good conductive effect, thereby causing no impact on performance of the device.

Abstract: A foreign wireless communication system is operated in a local communication network as if the foreign wireless communication system were a local wireless communication system. A data communication link is established between the wireless communication system and a service provider in a local wireless communication network. An outgoing request for authentication information is communicated from the wireless communication system to a remote administration system over the data communication link. The authentication information is received over the data communication link from the administration system and is transmitted over a signal link from the wireless communication system to the service provider. A requested wireless communication service is received at the wireless communication system based on authentication of the wireless communication system by the service provider using the authentication information.

Patent EP-4254417-A3 (EP)
Inventor: LO YUK-MING DENNIS
IPC: C12Q1/68
Filed: 2018-11-02
Abstract: Size-band analysis is used to determine whether a chromosomal region exhibits a copy number aberration or an epigenetic alteration. Multiple size ranges may be analyzed instead of focusing on specific sizes. By using multiple size ranges instead of specific sizes, methods may analyze more sequence reads and may be able to determine whether a chromosomal region exhibits a copy number aberration even when clinically-relevant DNA may be a low fraction of the biological sample. Using multiple ranges may allow for the use of all sequence reads from a genomic region, rather than a selected subset of reads in the genomic region. The accuracy of analysis may be increased with higher sensitivity at similar or higher specificity. Analysis may include fewer sequencing reads to achieve the same accuracy, resulting in a more efficient process.

Patent EP-0033223-A3 (EP)
IPC: H02G7/14
Filed: 1981-01-21
Abstract: In a vibration absorber for use with aerially suspended 
conductors and cables, there is described an improved vibra­
tion absorber wherein wind or turbulence induced vibrations 
resulting in travelling waves on conductors cables are 
absorbed so as to prevent damage to or failure of conductors 
and related hardware due to fatigue. Known devices, particu­
larly dampers and spacer dampers, attempt to control merely 
the amplitude of the waves produced on the conductor and 
are therefore ineffective in preventing the formation of such 
waves and the damage that may result. In this invention, a 
vibration absorber comprising a piston and cylinder device 
whereby a travelling wave displaces the piston or the cylinder 
relative to one another causing a fluid contained within the 
cylinder to be displaced through an orifice in the piston. The 
absorbing system thus defined has a mechanical dissipative 
impedance of value R to inhibit the reflection of a wave propa­
gated on the conductor whereby the wave is absorbed. The 
value of R is in the range of .5 TM to 2.0 TM where T is the 
tension of the conductor and M is the mass of the conductor 
per unit length.

Abstract: A directional filter is constructed with a plurality of 
grooves (15) extending into a plate (13) from one side (16) 
thereof. The grooves (15) have a light absorbing characteristic 
which causes them to absorb light impinging upon the 
grooves, particularly light impinging upon the grooves (15) 
from within the plate (13). Since all light passing beyond a 
certain angle  must impinge upon the grooves (13), and only 
a small percentage of light passing parallel to the cut of the 
grooves (15) would impinge upon the grooves (15), the filter 
has a high ratio of attenuation of unwanted verses wanted 
light.

Abstract: The invention relates to a control circuit for controlling 
the energization of a handle operator/adapted for use with a 
circuit breaker to effect movement of the circuit breaker 
handle from one position thereof to another.  
     The control circuit employs a monostable multivibrator 
including a normally non-conducting switch (426) which, 
upon initial closure of a contact switch (422), is rendered 
conducting to supply an energizing pulse to an operating 
solenoid (424) of the handle operator, and including timing 
means (442-448) for rendering the switch (426) nonconduct­

the handle operator to complete movement of the circuit 
breaker handle (42). The timing means automatically in­
creases said time interval in proportion to any drop in the 
energizing voltage sensed.
