- Redistribution layer for substrate contacts
- (57) Abstract
A structure with an interconnection layer for redistribution of electrical connections includes a plurality of first electrical connections disposed on a substrate in a first arrangement. An insulating layer is disposed on the substrate over the first electrical connections. A plurality of second electrical connections is disposed on the insulating layer on a side of the insulating layer opposite the plurality of first electrical connections in a second arrangement. Each second electrical connection is electrically connected to a respective first electrical connection. An integrated circuit is disposed on the substrate and is electrically connected to the first electrical connections. The first electrical connections in the first arrangement have a greater spatial density than the second electrical connections in the second arrangement.

Description
The present invention relates to electrical interconnections for integrated circuits in multiple layers on a substrate.
Flat-panel displays are widely used in conjunction with computing devices, in portable devices, and for entertainment devices such as televisions. Such displays typically employ a plurality of pixels distributed over a display substrate to display images, graphics, or text. For example, liquid crystal displays (LCDs) employ liquid crystals to block or transmit light from a backlight behind the liquid crystals and organic light-emitting diode (OLED) displays rely on passing current through a layer of organic material that glows in response to the electrical current.
Most flat-panel displays use active-matrix thin-film transistors formed in a thin semiconductor layer on a substrate to control an array of light-emitting or light-controlling elements. However, the thin layer of semiconductor material is typically amorphous or has localized crystals, for example in amorphous silicon or polysilicon. These semiconductor material structures have a much lower performance than crystalline semiconductors found in typical integrated circuits. Moreover, it is difficult and expensive to make thin-film semiconductor structures on large substrates, limiting the size of integrated flat-panel devices such as displays. Passive-matrix control structures that do not require a thin-film semiconductor layer are also known but are limited in size resolution, and refresh rate.
