Abstract:
An embodiment provides a semiconductor device including a semiconductor substrate having first and second surfaces opposite each other, a channel pattern disposed on the first surface of the semiconductor substrate; source/drain patterns disposed on the first surface of the semiconductor substrate and disposed at both sides of the channel pattern; first and second etch stop films disposed on the first surface of the semiconductor substrate; a contact electrode electrically connected to the source/drain patterns; a lower wire structure disposed on the second surface of the semiconductor substrate; and a through via that passes through the semiconductor substrate, the first etch stop film, and the second etch stop film to connect the contact electrode and the lower wire structure, wherein the through via includes a first portion contacting the contact electrode and a second portion contacting the first portion and disposed between the first portion and the lower wire structure.
Abstract:
A processor includes an instruction pipeline that sequentially processes an original instruction and a duplicate instruction, which is generated by duplicating the original instruction. An original register file stores a result obtained by processing the original instruction in the instruction pipeline within a register of a nth index thereof. A duplicate register file stores a result obtained by processing the duplicate instruction in the instruction pipeline within a register of a nth index thereof. A comparing unit compares the register of the nth index in the original register file with the register of nth index in the duplicate register file and outputs an error detection signal, in response to a control signal.
Abstract:
A method of forming a metal interconnection of semiconductor device is provided. The method includes forming a low-k dielectric layer including an opening; forming a barrier metal pattern conformally covering a bottom surface and an inner sidewall of the opening; forming a metal pattern exposing a part of the inner sidewall of the barrier metal pattern in the opening; forming a metal capping layer on the top surfaces of the metal pattern and the low-k dielectric layer using a selective chemical vapor deposition process, wherein the thickness of the metal capping layer on the metal pattern is greater than the thickness of the metal capping layer on the low-k dielectric layer; and forming a metal capping pattern covering the top surface of the metal pattern by planarizing the metal capping layer down to the top surface of the low-k dielectric layer.
