    摘要: This invention discloses a thin film transistor and the preparation method thereof, an array substrate, and a display panel, so as to solve the problem that the active layer is prone to be corroded when a metal oxide thin film transistor is produced by a back channel etching process. The preparation method comprises: forming a gate electrode metal thin film on a base substrate, and allowing the gate electrode metal thin film to form a gate electrode metal layer comprising a gate electrode by a patterning process; forming a gate electrode insulating layer on the gate electrode metal layer; forming an active layer on the gate electrode insulating layer; preparing a metal nanoparticle layer on the active layer, said metal nanoparticle layer being used as an etching protection layer; forming a source and drain electrode metal thin film on the base substrate on which the above processes are finished, and allowing the source and drain electrode metal thin film to form a source and drain electrode metal layer comprising a source electrode and a drain electrode by a patterning process, wherein the source electrode and the drain electrode cover a part of the metal nanoparticle layer; removing or oxidizing the part of the metal nanoparticle layer which is not covered by the source electrode and the drain electrode in an oxygen-containing atmosphere; and forming a passivation layer on the source and drain electrode metal layer.

    摘要: A high power, high frequency, metal-semiconductor field-effect transistor comprises a bulk single crystal silicon carbide substrate (10), an optional first epitaxial layer (12) of p-type conductivity silicon carbide formed upon the substrate, and a second epitaxial layer (14) of n-type conductivity silicon carbide formed upon the first epitaxial layer. The second epitaxial layer (14) has two separate well regions (18, 16) therein that are respectively defined by higher carrier concentrations of n-type dopant ions than are present in the remainder of the second epitaxial layer. Ohmic contacts (20, 22) are positioned upon the wells for respectively defining one of the well regions (18) as the source and the other (16) as the drain. A Schottky metal contact (24) is positioned upon a portion of the second epitaxial layer (14) that is between the ohmic contacts (20, 22) and thereby between the source and drain for forming an active channel in the second epitaxial layer when a bias is applied to the Schottky contact (24).

    摘要: A photovoltaic cell is formed by combining a spray process, forming a crystalline layer containing cadmium and sulfur, and an evaporation process, depositing copper chloride for converting to Cu x S. The crystals containing cadmium and sulfur are heated in an atmosphere of cadmium and chlorides to obtain crystals having at least one dimension greater than 0.5 micron and a planar layer of Cu x S is formed on the large crystals. A layer of Cu x S having a thickness of 0.5-1.0 micron is obtained. Electrodes are formed from evaporated gold or chromium or a metallic paste including silver or copper. Zn x Cd 1-x S may be substituted for CdS through at least part of the crystalline layer for improved Voc.
