Patent number: 6549050Abstract: A circuit and method are provided for ensuring a non-desired output state of a latch or flip-flop cannot be produced. The latch can be configured as a set dominant, reset dominant, or memory dominant circuit by simply placing programmed voltage values on select transistors of the latch. The programmed values will cause either the set input, the reset input, or both set and reset inputs to have a complimentary effect on the output signals even though the set and reset inputs are at the same logic level. The set, reset, and memory dominant circuit is identical in structure; however, the set, reset, and memory dominant features are derived solely by placing programmed values on corresponding transistors within the identical structure. A generic latch circuit can, therefore, be said to operate in one of three dominant ways depending on the programmed values chosen by a selector and fed to a prioritizer.Type: GrantFiled: September 13, 2001Date of Patent: April 15, 2003Assignee: Cypress Semiconductor Corp.Inventors: Steven C. Meyers, Terry D. Little

Patent number: 6549221Abstract: Systems and methods for presenting (e.g., displaying) a hierarchical structure are presented. The hierarchical structure includes multiple elements and defines hierarchical relationships between the elements. The hierarchical structure may be embodied within an electronic document such as a Web document, an interactive application program, or a map divided into sections. Each element has a “presentation property” which may be a value or a function. One of the elements has “focus” (e.g., as created, by default, etc.). A “branch isolation” method includes forming a tree-like model of the hierarchical structure having multiple nodes and at least one branch. Each node represents one of the elements. One node is a root node and occupies a highest level in the hierarchical structure. A given branch connects a first node in a first level to a second node in a level directly below the first level. Each branch represents a hierarchical relationship between connected nodes.Type: GrantFiled: December 9, 1999Date of Patent: April 15, 2003Assignee: International Business Machines Corp.Inventors: Frances C.

Patent number: 6534378Abstract: The present invention advantageously provides a method for retaining a substantially transparent dielectric above alignment marks during polishing of the dielectric to ensure that the alignment marks are preserved for subsequent processing steps. According to an embodiment, alignment marks are etched into a semiconductor substrate. Thereafter, a pad oxide layer is deposited across the substrate surface, followed by the deposition of a first nitride layer. Isolation trenches which are deeper than the alignment mark trenches are formed spaced distances apart within the substrate. Optical lithography may be used to define the regions of the first nitride layer, the pad oxide layer, and the substrate to be etched. The isolation trenches thus become the only areas of the substrate not covered by the pad oxide layer and the first nitride layer. A substantially transparent dielectric, e.g., oxide, is then deposited across the semiconductor topography to a level spaced above the first nitride layer.Type: GrantFiled: August 31, 1998Date of Patent: March 18, 2003Assignee: Cypress Semiconductor Corp.Inventors: Krishnaswamy Ramkumar, Chidambaram G.

Patent number: 6531364Abstract: A method is presented for forming a transistor wherein polysilicon is preferably deposited upon a dielectric-covered substrate to form a sacrificial polysilicon layer. The sacrificial polysilicon layer may then be reduced to a desired thickness. Thickness reduction of the sacrificial polysilicon layer is preferably undertaken by oxidizing a portion of the sacrificial polysilicon layer and then etching the oxidized portion. As an option, the sacrificial polysilicon layer may be heated such that it is recrystallized. The sacrificial polysilicon layer is preferably annealed in a nitrogen-bearing ambient such that it is converted to a gate dielectric layer that includes nitride. Polysilicon may be deposited upon the gate dielectric layer, and select portions of the polysilicon may be removed to form a gate conductor. LDD and source/drain areas may be formed adjacent to the gate conductor.Type: GrantFiled: August 5, 1998Date of Patent: March 11, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Mark I.

Patent number: 6522776Abstract: A method, system, and storage medium for determining retide tilt in a lithographic system is provided. Test patterns contained on a reticle are printed in a photoresist located on an upper surface of a semiconductor substrate by a lithographic system. The test patterns may include three posts of different diameters wherein one of the diameters is approximately equal to the minimum allowable feature size printable by the lithographic system. Images of the test patterns are measured by a scanning electron microscope under the control of a computer system.
