A print head assembly and a printer using the same are disclosed. The print head assembly includes: a bracket, a print head and an elastic element. The bracket includes a first bracket body having a cavity and a lid covered on the opening of the cavity. A window is opened on the first bracket body. The print head is accommodated in the cavity of the first bracket body and hinged to the first bracket body via a first rotary shaft. The surface of a heating element of the print head is matched with the window and faces an outside paper pressing roller. The elastic element biases towards the print head so as to make the surface of the heating element of the print head have a tendency to extend outside the window. The print head assembly is capable of being detached as a whole, thus the requirements of performing single-sided printing and duplex printing in the same printer is achieved.

Field effect transistors fabricated using atomic layer doping processes are disclosed. In accordance with an embodiment of an atomic layer doping method, a semiconducting surface and a dopant gas mixture are prepared. Further, a dopant layer is grown on the semiconducting surface by applying the dopant gas mixture to the semiconducting surface under a pressure that is less than 500 Torr and a temperature that is between 300° C. and 750° C. The dopant layer includes at least 4×1020 active dopant atoms per cm3 that react with atoms on the semiconducting surface such that the reacted atoms increase the conductivity of the semiconducting surface.

A scanning-printing integrated apparatus comprises a scanning passage (1), a printing passage (3) communicated with the scanning passage (1), a transitional passage (2) providing printing medium to the printing passage (3), a first driving mechanism for driving the paper conveying roller (12) of the scanning passage (1) and the paper conveying roller (312) of the printing passage (3), and a second driving mechanism for driving the paper conveying roller (21) of the transitional passage (2) and the paper conveying roller (312) of the printing passage (3). The two ends of the paper conveying roller (312) of the printing passage (3) are respectively transmission-connected to the first driving mechanism and the second driving mechanism via one-way bearings (71, 72). By providing one-way bearings at the two ends of the paper conveying roller of the printing passage, the first driving mechanism and the second driving mechanism work independently without interfering with each other, so that the two driving mechanisms drive the manuscript or printing paper to be freely conveyed in the scanning passage, the printing passage and the transitional passage without increasing loads.

A method of forming a nitride film by hydride vapor phase epitaxy, the method including: sequentially disposing at least one group III metal source including impurities and a substrate in an external reaction chamber and an internal reaction chamber sequentially located in the direction of gas supply and heating each of the external reaction chamber and the internal reaction chamber at a growth temperature; forming a metal chloride by supplying hydrogen chloride gas and carrier gas into the external reaction chamber to react with the group III metal source and transferring the metal chloride to the substrate; and forming the nitride film doped with the impurities on the substrate by reacting the transferred metal chloride with nitrogen source gas supplied to the internal reaction chamber.
摘要:
An integrated semiconductor structure containing at least one device formed upon a first crystallographic surface that is optimal for that device, while another device is formed upon a second different crystallographic surface that is optimal for the other device is provided. The method of forming the integrated structure includes providing a bonded substrate including at least a first semiconductor layer of a first crystallographic orientation and a second semiconductor layer of a second different crystallographic orientation. A portion of the bonded substrate is protected to define a first device area, while another portion of the bonded substrate is unprotected. The unprotected portion of the bonded substrate is then etched to expose a surface of the second semiconductor layer and a semiconductor material is regrown on the exposed surface. Following planarization, a first semiconductor device is formed in the first device region and a second semiconductor device is formed on the regrown material.
