Benefits of technology

The patent text is about a way to make a three-dimensional semiconductor device with more data storage capacity. This can be useful in making computer chips or other electronic devices. The invention involves increasing the depth of a page, which is a unit of data storage in the device. This can allow for more data to be stored and processed by the device.

Problems solved by technology

However, since the equipment that may be used to form fine patterns is relatively expensive, there may be limitations as to economically increasing the integration of a two-dimensional memory semiconductor device.

Embodiment Construction

[0038]Example embodiments of the inventive concepts will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. Example embodiments of the inventive concepts may, however, be embodied in many different forms and should not be construed as being 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 concept of example embodiments to those of ordinary skill in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements, and thus their description will be omitted.

[0039]It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as bein...

Abstract

A three-dimensional semiconductor device includes bit lines provided on a substrate, a gate structure provided between the substrate and the bit lines, a common source line provided between the gate structure and the bit lines, and channel pipes connecting the bit lines to the common source line. Each of the channel pipes may include a pair of vertical portions extending through the gate structure and a horizontal portion connecting the vertical portions. The pair of vertical portions are provided under a pair of the bit lines arranged adjacent to each other, respectively.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 057,669 filed on Oct. 18, 2013 which application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2012-0142895, filed on Dec. 10, 2012, in the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference herein in its entirety.BACKGROUND OF THE INVENTION[0002]Example embodiments of the inventive concept relate to three-dimensional semiconductor devices.[0003]In semiconductor devices, increased integration may be an important factor in realizing high performance, low cost devices. In a two-dimensional memory semiconductor device or in a planar memory semiconductor device, integration can be affected by techniques for forming fine patterns, as integration may be determined by the area occupied by a unit memory cell. However, since the equipment that may be used to form fine patterns is relatively expensive, t...
