Problems solved by technology

[0005] However, due to the relatively low thermal conductivity of flexible substrates, heat sinks mounted on the bottom surface of flexible substrates can be inefficient
In addition, such heat sinks often have a plate shape by using metal such as aluminum, which may reduce the flexibility of the COF type semiconductor package
Also, over time and in normal use, the heat sink may detach from the flexible substrate

Embodiment Construction

[0040] Hereinafter, specific embodiments will be described in detail with reference to the accompanying drawings. However, this invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0041]It will also be understood that when an element or layer is referred to as being "on" another layer, it can be directly on the other layer, film, region or panel, or one or more intervening elements or layers may also be present. On the other hand, it should be understood that when an element is directly disposed on or connected to another element, there cannot be another element in between. In addition, although ordinal numbers such as "first", "second" and "third" are used in various embodiments of the present invention to describe various elements, com...

Abstract

Provided are an apparatus and method of packaging semiconductor devices mounted on a flexible substrate having a longitudinally extending tape shape and on which packaging areas are defined along the extending direction thereof. The flexible substrate is transferred through a packaging module. An empty area, on which a semiconductor device is not mounted, is detected by a camera from among the packaging areas. Heat dissipation paint composition is applied on at least one semiconductor device located in a processing region of the packaging module by a screen printing process. Thus, a heat dissipation layer configured to package the semiconductor device is formed. Here, operations of the packaging module are controlled by a control unit so that the packaging process is omitted with respect to the empty area.

Description

technical field [0001] The present invention relates to a method of packaging a semiconductor device and an apparatus for performing the method, and more particularly to a package mounted on a flexible substrate such as a chip-on-film (COF) tape, a tape carrier package (TCP) tape, etc. A method of a semiconductor device, and an apparatus for performing the method. Background technique [0002] In general, a display device such as a liquid crystal display (LCD) may include a liquid crystal panel and a backlight unit disposed on a backside of the liquid crystal panel. A semiconductor device such as a driver integrated circuit (IC) may be used to drive the liquid crystal panel. These semiconductor devices may be connected to the liquid crystal panel using packaging techniques such as COF, TCP, chip on glass (COG), and the like. [0003] High resolution display devices may require increased drive loads to be provided by the semiconductor devices. In the particular case of COF...
