Abstract: A method for forming a semiconductor device is provided. A first patterned mask is formed on the substrate, the first patterned mask having a first opening therein. A second patterned mask is formed on the substrate in the first opening, the first patterned mask and the second patterned mask forming a combined patterned mask. The combined patterned mask is formed having one or more second openings, wherein one or more unmasked portions of the substrate are exposed. Trenches that correspond to the one or more unmasked portions of the substrate are formed in the substrate in the one or more second openings.

Abstract: A tape and reel inspection system is provided with OCR testing of devices, network retrieval of device lot information, and automatic teaching of image patterns. Each device lot is typically accompanied by a travel sheet, which includes a history for the device lot. The travel sheet may include a bar code to allow the system to receive the device lot number while reducing the possibility of human error. The system performs OCR on a first device. The system communicates with a database to obtain lot information. The system combines lot information and package information to form marking information. The system then compares the contents of the markings with line information obtained from the marking information. Once a first device passes the OCR test, the system trains an image of the first device. Image training may be done automatically without intervention from the operator. If a subsequent device fails the image test, the inspection system automatically performs OCR on the failed device.

Abstract: Airborne navigation and communication systems are disclosed including a VOR/LOC (VHR Omnirange/Localizer) receiver and a communication transceiver each with separate control and display panels. Each panel includes a ten push-button press keys numbered 0-9, a function controller for operating mode selection and general control, a pair of digital displays (5 digits each) for displaying keyboard channel selection including an active channel and a standby channel and additional data, three function press keys--one for switching a standby channel into the active channel or vice versa or resetting the timer or changing the digital bearing display from "TO" to "FROM", a second key for either recalling a channel or backing up to a digit for correction during data entry, and a third key for storing frequency in memory locations or entering data.
