The invention relates to an atomic layer deposition (ALD) method which includes the steps as follows: first precursor gas flows to a semiconductor substrate in an atomic layer deposition room and a first scattered monolayer is formed; inert purge gas flows to the semiconductor substrate in the atomic layer deposition room; second precursor gas flows into the atomic layer deposition room and reacts with the first precursor gas that forms the first monolayer and a first scattered compound monolayer is formed; the inert purge gas flows into the atomic layer deposition room; and a second scattered compound monolayer is formed on the semiconductor substrate by referring to the technique which forms the first scattered compound monolayer. The method forms the first scattered compound monolayer and the second compound monolayer on the semiconductor substrate. The invention also provides a semiconductor device and the charge trap layer of the semiconductor device is a dielectric layer which contains the first scattered compound monolayer and the second compound monolayer formed by adopting an atomic deposition method.

An epitaxial substrate for an electronic device having a Si single crystal substrate, a buffer as an insulating layer formed on the Si single crystal substrate, and a main laminated body formed by plural group III nitride layers epitaxially grown on the buffer, wherein a lateral direction of the epitaxial substrate is defined as an electric current conducting direction. The buffer including at least an initially grown layer in contact with the Si single crystal substrate and a superlattice laminate constituted of a superlattice multilayer structure on the initially grown layer.

The invention discloses a novel screw rotor tooth shape of a twin screw compressor. The novel screw rotor tooth shape comprises a male rotor tooth shape and a female tooth shape, and is characterized in that each tooth shape on the end surface of the male rotor and the female rotor consists of six segments of curves in smooth connection, and the curves comprise an ellipse arc, a circular arc and an enveloping line thereof, wherein the six segments of curves of each tooth of the female rotor comprise: a tooth curve ellipse arc a2b2, a tooth curve circular arc b2c2, a tooth curve arc c2d 2, a tooth curve circular arc enveloping line d2e2, a tooth curve circular arc e2f2 and a tooth curve circular arc f2g2, wherein the curves of each tooth are connected in sequence. The six segments of curves of each tooth of the male rotor comprise a tooth curve ellipse arc enveloping line a1b1, a tooth curve circular arc enveloping line b1c1, a tooth curve pin tooth circular arc c1d1, a tooth curve circular arc d1e1, a tooth curve circular arc enveloping line e1f1and a tooth curve circular arc f1g1; and the curves of each tooth are connected in sequence. Therefore, when the tooth surfaces are in conjugate meshing, the tooth surfaces of two rotors are improved to 'belt' sealing from 'line' sealing, so as to improve the sealing effect obviously, contribute to forming a lubricating oil film and reducing tooth surface abrasion, and prolong the rotor life greatly.

The present application discloses an OLED display device and a manufacturing method thereof. The OLED display device includes a substrate, an anode layer, a pixel definition layer, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer, and a spacer. column; a barrier column located on an area other than the spacer column on the pixel spacing region, the barrier column at least penetrates the hole transport layer and the hole injection layer; in the OLED display device provided by the present invention, in two adjacent color Barrier columns are made on the pixel spacing area between the light-emitting pixels, and at least one of the two internal angles of the barrier column close to the pixel spacing area is greater than 90°, so that when organic materials such as hole transport layers and hole injection layers are evaporated, it is possible to The hole transport layer and the hole injection layer are disconnected at the barrier column, thereby reducing the lateral leakage between a certain light-emitting pixel and adjacent light-emitting pixels when a light-emitting pixel is lit, and preventing other light-emitting pixels from stealing light. Problems, improve product yield.
