Abstract

The invention relates to a high-reliability IPTV set-top box and a manufacturing method thereof, comprising a power supply, an interface unit, a housing, and an internal chip unit, and the internal chip unit specifically includes: a semiconductor substrate, an epitaxial layer, a source, a drain doping area, and a channel area , grid structure, thermally conductive material, and metal backplane; wherein, the thermally conductive material is divided into two parts, the first thermally conductive material is a doped semiconductor material, and the second thermally conductive material is a metal material; the first thermally conductive material is located above the second thermally conductive material, The first heat conduction material is in contact with the lower surface of the epitaxial layer, and the second heat conduction material is in contact with the metal back plate. The present invention fills the heat-conducting material combined with doped semiconductor and metal in the semiconductor substrate, and forms a metal backplate in contact with the heat-conducting material under the semiconductor substrate, which can quickly lead out the internal generation of the transistor unit without affecting the semiconductor performance of the semiconductor substrate. of heat.

Description

technical field [0001] The invention relates to the field of smart TVs, in particular to a high-reliability IPTV set-top box. Background technique [0002] A digital video converter box, commonly called a set-top box or set-top box, is a device that connects a television to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is not only the image and sound that can be provided by analog TV, but also the digital content, including electronic program guide, Internet web pages, subtitles, etc., so that users can watch digital TV programs on existing TV sets, and can Interactive digital entertainment, education and commercialization over the web. [0003] IPTV is a widely used interactive Internet TV at present. It accesses broadband through broadband Internet, uses set-top boxes or...
