A semiconductor structure having a plurality of gate stacks on a semiconductor substrate provided with a gate dielectric. The gate stacks have a lower first layer made of polysilicon, an overlying second layer made of a metal silicide, and an upper third layer made of an insulating material, and a sidewall oxide on the sidewalls of the first and second layers. The sidewall oxide is thinned or removed on one of the sidewalls, and the gate stacks have sidewall spacers made of the insulating material.

In one embodiment, an integrated circuit includes a memory array having a plurality of capacitors for storing data of an initial state in the memory array in an initial state. The integrated circuit also includes circuitry for occasionally inverting the data stored by the plurality of capacitors and tracking whether the current state of the data stored by the plurality of capacitors corresponds to the initial state. The circuitry inverts the data read out of the memory array during a read operation when the current state of the data does not correspond to the initial state.

A method of manufacturing an integrated circuit provides a metrology mark (e.g., alignment mark or overlay mark). The method includes forming a first plurality of first structures arranged in a matrix in a substrate. Portions of the matrix are covered with a mask such that first portions of the matrix are left exposed and second portions of the matrix are covered. Signal response properties of exposed ones of the first structures in the matrix are altered to form a metrology mark. The metrology mark includes first and second mark portions with different signal response properties and which are aligned to a virtual grid. The evaluation of precisely positioned metrology marks may be improved with low impact on process complexity.

Integrated circuit and programmable delay. One embodiment provides an integrated circuit including a programmable delay element having a plurality of single delay cells. The delay cells include a first input and a second input and a first output. The delay cells are arranged to form a chain such that the first output of a preceding delay cell is coupled to the second input of a successive delay cell. The first inputs of any delay cells are configured to receive an input signal to be delayed. The delay cells out of the plurality of delay cells is configured to constitute a starting point of a signal path including any of the delay cells arranged downstream of the starting point. The first output of the last delay cell in the chain forms an output of the programmable delay element.

The present invention relates to a method for depositing a dielectric material comprising a transition metal compound. After providing a substrate, a first pre-cursor comprising a transition metal compound and a second pre-cursor predominantly comprising at least one of water vapour, ammonia and hydrazine are successively applied on the substrate for forming a first layer of transition metal containing material. In a next step the first pre-cursor and a third pre-cursor comprising at least one of ozone and oxygen are successively applied on the first layer for forming a second layer of the transition metal containing material.
摘要:
An arrangement of magnetic liners for the bit lines or word lines of an MRAM device that reduces or eliminates stray magnetic fields at the ends of the magnetic liners, thereby reducing the occurrence of offset fields over portions of the MRAM device due to the magnetic liners is described. The orientation of magnetization of adjacent magnetic liners is alternated, causing the end poles of the magnetic liners to cancel each other. The shapes of the ends of the magnetic liners are alternated to vary their switching fields. Methods are described that use this ability to vary the switching fields to alternate the orientation of magnetization of the magnetic liners.
