摘要:
A method of replacing a top oxide around a storage element of a memory device is provided. The method can involve removing a core first poly and core first top oxide in a core region while not removing a periphery first poly in a periphery region on a semiconductor substrate; forming a second top oxide around a storage element in the core region and on the periphery first poly in the periphery region; forming a second poly over the semiconductor substrate in both the core and periphery regions; removing the second poly and second top oxide in the periphery region; and forming a third poly on the semiconductor substrate in both the core and periphery regions.

Methods of forming a memory cell containing two split sub-lithographic charge storage nodes on a semiconductor substrate are provided. The methods can involve forming two split sub-lithographic charge storage nodes by using spacer formation techniques. By removing exposed portions of a first poly layer while leaving portions of the first poly layer protected by the spacers, the method can provide two split sub-lithographic first poly gates. Further, by removing exposed portions of a charge storage layer while leaving portions of the charge storage layer protected by the two split sub-lithographic first poly gates, the method can provide two split, narrow portions of the charge storage layer, which subsequently form two split sub-lithographic charge storage nodes.

摘要:
Methods and systems for generating masks for spacer formation are disclosed. As a part of a disclosed method, a predefined final wafer pattern is accessed, areas related to features in the predefined final wafer pattern are identified and a template mask is formed based on the identified areas for forming spacers on a wafer. Subsequently, a mask is formed for use in the removal of portions of the spacers to form an on wafer pattern that corresponds to the predefined final wafer pattern.
摘要:
A method of forming a metal gate in a wafer. PolySi1-xGex and polysilicon are used to form a tapered groove. Gate oxide, PolySi1-xGex, and polysilicon is deposited on a wafer. A resist pattern is formed. A portion of the polysilicon, PolySi1-xGex, and gate oxide is removed to provide a tapered profile. The resist is removed; a dielectric liner is deposited, and then at least a portion of the dielectric liner is removed, thereby exposing the polysilicon and leaving the dielectric liner in contact with the polysilicon, PolySi1-xGex, and gate oxide. A dielectric is deposited, and a portion is removed thereby exposing the polysilicon. The polysilicon, PolySi1-xGex, and gate oxide is removed from inside the dielectric liner, thereby leaving a tapered gate groove. Metal is then deposited in the groove.

摘要:
An improvement to a method of forming an integrated circuit. An etch stop layer is formed to overlie the front end processing layers of the integrated circuit. Support structures are formed that are disposed so as to support electrically conductive interconnects on various levels of the integrated circuit. Substantially all of the non electrically conductive layers above the etch stop layer that were formed during the fabrication of the interconnects are removed.

A handheld electronic game comprises a rotational body, an processor, a storage cell for powering the processor, a display screen for displaying images processed by the processor, and a number of keys for providing game-control input to the processor. A generator is electrically connected to the storage cell for applying voltage to and recharging the storage cell. There is also a flywheel rotatably with respect to the body, which is connected to the generator and provides a mass moment of inertia enabling rotation of the body relative thereto during dynamic rotational movement of the body.

摘要:
A method of making a thin gate dielectric includes implanting a barrier substance into a region of a silicon substrate. A capacitance-increasing material is implanted into the silicon substrate. An outside layer of the silicon substrate is oxidized to form a first silicon oxide layer. The silicon substrate is oxidized between the first silicon oxide layer and the region.
