Title: Utility, method and device for handling a first set of higher-priority functions and a second set of lower-priority functions
Inventor: FRID ALEKSANDR
IPC: G06F1/32
Filed: 1999-03-24
Granted: 2001-06-07
Abstract: A single controller handles keyboard functions and ACPI configuration and power management functions, while providing priority to keyboard functions so that there is no end user-perceptible compromise of keyboard functionality. When an interrupt is received by the microcontroller, it is determined whether the interrupt is an embedded controller interrupt received at the embedded controller host interface or a keyboard interrupt received at the keyboard host interface. If the interrupt is a keyboard intenuptl the keyboard function is handled in a standard fashion. If the interrupt is an embedded controller interrupt for an ACPI configuration or power management function, a burst timer is started and the command is handled by a command dispatcher. If the embedded controller is in burst mode, multiple commands may be received during a burst period. Commands which are not completed before the expiration of the burst timer are aborted, and a data return vector is set to the absolute address at the point of abortion in the firmware. Aborted commands are resumed on reception of the next embedded controller interrupt by continuation of the process at the data return vector address.

Title: Method and compact system for inspecting a reticle with high accuracy
Inventor: TAKAYAMA NAOHISA
IPC: G03F1/84
Filed: 1998-11-24
Granted: 2000-05-21
Abstract: Even though a laser interferometer is affected by the changes in the environment, a reticle can be inspected with a high accuracy by synthesizing a reference image corrected appropriately to compare with an optical image. The reticle on which a pattern is plotted in advance is irradiated with a light beam (m) to obtain the optical image (p) from the transmitted light to compare the optical image with the reference image synthesized by converting draft data used at plotting the pattern (u) and the detected defects of the pattern (w). The reference image is corrected based on the deviation data obtained at the preceding pattern defect detection. The deviation data is the difference between a difference (an initial distance value) between a completion position data and an initiation position data measured before a laser interferometer is affected by the changes in the environment and a difference (a distance data) between the completion position data and the initiation position data measured after being affected by the changes in the environment, and is obtained using a scale which is hardly affected by the changes in the environment (t).

Title: Manufacturing method for unbounded and automatically aligned polycide with multiple layers of interconnects and metal contact plug
Inventor: JENG SHIANG-YUAN
IPC: H01L23/522
Filed: 1999-07-13
Granted: 2001-01-01
Abstract: The present invention relates to a manufacturing method for unbounded and automatically aligned polycide with multiple layers of interconnects and metal contact plug. AN etching stop layer and a flat insulation layer are formed above the device on the substrate. The contact window is etched to the etching stop layer in the insulation layer and the etching stop layer on the N- contact region is removed. A N+ type doped polycide layer is deposited and the second contact window is etched to the etching stop layer in the insulation layer with the polycide of N+ and P+ contacts of the substrate. The etching stop layer is selectively removed and a conductive barrier and a metal layer are deposited on the surface comprising a second etching barrier. Then, those layers are defined to form interconnects and simultaneously form the polycide contact plugs connecting to N- contact and forming the metal contact plug connected to the N+ and P+ contacts. Now, the via is etched to the contact plug in the second insulation layer. The polycide contact plug connected to N- contact can reduce the current leakage and the metal contact connected to N+ and P+ contact can reduce the contact resistance (Rc). The contact plug can protect the substrate contact from damage during via etching and reduce the aspect ratio to enhance the contact reliability.
