Title: Enhanced bonding between iii-v material and oxide material
Inventor: FESHALI AVI
IPC: H01L21/304
Filed: 2019-03-27
Abstract: When a III-V semiconductor material is bonded to an oxide material, water molecules can degrade the bonding if the water molecules become trapped at the interface between the III-V material and the oxide material. The water molecules can diffuse readily through the oxide material, and does not diffuse as readily through the III-V material or through silicon, forcing the III-V material against the oxide material can force the water molecules at the interface into the oxide material and away from the interface. The water molecules present at the interface can be forced during manufacturing through vertical channels in a silicon layer into a buried oxide layer to enhance bonding between the III-V material and the oxide material. The water molecules can be also forced through lateral channels in the oxide material, pass the periphery of the III-V material, and, through diffusion, out of the oxide material into the atmosphere.

Title: Method and apparatus for reducing number of radar target detection operations
Inventor: JEONG SO HEE
IPC: G01S13/58
Filed: 2019-03-28
Abstract: The present invention aims to reduce the number of fast Fourier transforms performed to obtain target information through a signal number determination technique. The configuration of the present invention is as follows. A distance is detected by calculating a distance frequency by performing a distance fast Fourier transform on a received signal. It is determined whether there is one target at the same distance by determining the number of targets. When it is determined that there is one target, an angle is detected by calculating the distance frequency of the receiving channels (range FFT), and speed is detected by performing a fast Fourier transform (Doppler FFT) on one channel. When there are multiple targets at the same distance through the determination of the number of targets, distance frequencies are obtained for all chirps of all channels in the same manner as in a conventional method. The fast Fourier transform (Doppler FFT) is performed once more with the distance frequency using a Doppler axis to select a value equal to or greater than a threshold value for the Doppler axis, determine the number of detections M, and detect an angle and velocity of the value at the Doppler axis.
