20090063867 | Method, System and Computer Program Product for Preventing Execution of Software Without a Dynamically Generated Key - A method, system and computer program product for partitioning the binary image of a software program, and partially removing code bits to create an encrypted software key, to increase software security. The software program's binary image is partitioned along a random segment length or a byte/nibble segment length, and the code bits removed, and stored, along with their positional data in a software key. The software key is encrypted and is separately distributed from the inoperable binary image to the end user. The encrypted key is stored on a secure remote server. When the end user properly authenticates with the developer's remote servers, the encrypted security key is downloaded from the secure remote server and is locally decrypted. The removed code bits are reinserted into the fractioned binary image utilizing the positional location information. The binary image is then operable to complete execution of the software program. | 03-05-2009 |
20090063868 | Method, System and Computer Program Product for Preventing Execution of Pirated Software - A method, system and computer program product for preventing execution of pirated software. A file is loaded on an end user's computer containing a binary image that is generated by removing one or more code bits from an executable code. A request is sent to a remote server to return a software key required for execution of the executable code from the binary image. The software key is downloaded to the end user's computer on which the binary image is loaded. One or more bits from the software key is inserted into the appropriate location of the binary image to regenerate the executable code. The executable code is enabled for execution on the end user's computer only following the embedding of the one or more bits. | 03-05-2009 |
20090081813 | Method and Apparatus for Measurement and Control of Photomask to Substrate Alignment - A method, structure, system of aligning a substrate to a photomask. The method comprising: directing light through a clear region of the photomask in a photolithography tool, through a lens of the tool and onto a set of at least three diffraction mirror arrays on the substrate, each diffraction mirror array of the set of at least three diffraction mirror arrays comprising a single row of mirrors, all mirrors in any particular diffraction mirror array spaced apart a same distance, mirrors in different diffraction mirror arrays spaced apart different distances; measuring an intensity of light diffracted from the set of at least three diffraction mirror arrays onto an array of photo detectors; and adjusting a temperature of the photomask or photomask and lens based on the measured intensity of light. | 03-26-2009 |
20090195787 | Method and Apparatus for Measurement and Control of Photomask to Substrate Alignment - A method, structure, system of aligning a substrate to a photomask. The method includes: directing incident light through a pattern of clear regions transparent to the incident light in an opaque-to-the-incident-light region of a photomask, through a lens and onto a photodiode formed in a substrate, the photodiodes electrically connected to a light emitting diode formed in the substrate, the light emitting diode emitting light of different wavelength than a wavelength of the incident lights; measuring an intensity of emitted light from light emitting diode; and adjusting alignment of the photomask to the substrate based on the measured intensity of emitted light. | 08-06-2009 |
20100063781 | Enhanced Conductivity in an Airgapped Integrated Circuit - A method, program product and apparatus include extending lengths that project from a microchip trace into dielectric material. The extending lengths may not connect to another trace. Placement of the extending lengths may be optimized to increase the dissipation of heat from the trace, while maintaining an acceptable level of capacitance. | 03-11-2010 |
20100064270 | Cost-Benefit Optimization for an Airgapped Integrated Circuit - A computer implemented method, apparatus and program product provide automated processes for determining the most cost-effective use of airgaps in a microchip. The performance gains realized by using airgaps for a given net or layer may be calculated. These improvements may be paired to a monetary cost associated with implementing the applicable airgaps at that net/layer. The paired benefit and cost of the airgap scenario may be compared to other possible airgap uses at other layers/nets to determine which airgaps provide the best improvement for the lowest cost. | 03-11-2010 |
20100270682 | Implementing Vertical Airgap Structures Between Chip Metal Layers - A method and structure are provided for implementing vertical airgap structures between chip metal layers. A first metal layer is formed. A first layer of silicon dioxide dielectric is deposited onto the first metal layer. A vertical air gap is etched from the first layer of silicon dioxide dielectric above the first metal layer. A second layer of silicon dioxide dielectric is deposited and the vertical air gap is sealed. A next trace layer is etched from the second layer of silicon dioxide dielectric and a via opening is etched from the second and first layers of silicon dioxide dielectric. Then metal is deposited into the next trace layer and metal is deposited into the via opening. | 10-28-2010 |
