This disclosure provides a composite dielectric structure, a device having the same, and a fabrication method thereof. The fabrication method includes operations S1-S4. Operation S1: Depositing source and drain ohmic metals at designated locations on the surface of an epitaxial wafer; Operation S2: Using photoresist and electron beam lithography to create the required window for the gate structure; Operation S3: Etching a portion of the epitaxial wafer surface structure corresponding to the window and removing the photoresist to fabricate a gate trench; Operation S4: Growing AlN / SiN within the gate trench. X Composite dielectrics enable the fabrication of devices with composite dielectric structures.

The utility model discloses a kind of unpacking systems, including partition, the unpacking area of being arranged in the partition one side and the processing area being arranged in the partition other side, unpacking area is equipped with conveying track, bag cutting device and box bag separation station, bag cutting device is arranged between partition and conveying track, partition and the box bag separation station corresponding place are equipped with the feed inlet for with the notch of outer package bag butt joint, first inclined guide part for guiding the laminar flow of processing area to flow to feed inlet and second inclined guide part for guiding the laminar flow of feed inlet place backflow to processing area are equipped on partition.When nest box is pushed out from the notch of outer package bag, it can directly enter feed inlet, then enter processing area, thereby greatly shorten the time of nest box exposure, reduce pollution risk, first inclined guide part, second inclined guide part can improve the cleanliness of the area where feed inlet is located, further reduce the pollution risk of nest box, while it is beneficial to make the laminar flow of entire processing area layer flow type keep stable, controllable.

The invention discloses a star finder with an efficient heat dissipation and electromagnetic shielding structure, and relates to the technical field of star finders. A built-in electrical element and an integrated assembly are arranged in the star finder body, a shielding laminated layer with an electromagnetic shielding effect is further arranged on the inner wall of the star finder body, broadband electromagnetic interference suppression is achieved through a double-layer composite structure of the shielding laminated layer and a cross-core filtering assembly, and it is ensured that a control circuit works stably; by means of magnetic attraction linkage of the electromagnetic propelling assembly, the permanent magnet plate and the blocking plate, airflow is started according to needs, and control is stable and reliable; the controller generates an alternating magnetic field according to a set time sequence to drive the permanent magnet plate to reciprocate to form forced convection, and energy-saving heat dissipation is achieved. The Kalman filtering controller and the sensor array collect temperature, pressure and flow data in real time, precise closed-loop thrust control is achieved through recursion estimation, and therefore cooperative operation of waste heat driving, intelligent heat dissipation and precise posture adjustment is completed on the premise that electromagnetic compatibility is guaranteed.
