Publication number: 20010042705Abstract: A method for classifying defects includes imaging an inspected object. An image of a defect candidate is extracted from an image obtained by said imaging step. Said extracted defect candidate image is classified into a first category. Said extracted defect candidate image is classified into a second category. Said extracted defect candidate image and information relating to said classification into said first category and information relating to said classification into said second category are displayed on a screen.Type: ApplicationFiled: March 30, 2001Publication date: November 22, 2001Inventors: Ryou Nakagaki, Yuji Takagi, Kenji Obara, Yasuhiko Ozawa, Toshiei Kurosaki, Takehiro Hirai

Patent number: 6307171Abstract: An inventive method for sorting integrated circuit (IC) devices of the type having a substantially unique identification (ID) code, such as a fuse ID, includes automatically reading the ID code of each of the IC devices and sorting the IC devices in accordance with their automatically read ID codes. The inventive method can be used in conjunction with an IC manufacturing process that includes providing semiconductor wafers, fabricating the IC's on each of the wafers, causing each of the IC's to store its ID code, separating each of the IC's from its wafer to form IC dice, assembling the IC dice into IC devices, and testing the IC devices.Type: GrantFiled: August 31, 2000Date of Patent: October 23, 2001Assignee: Micron Technology, Inc.Inventor: Raymond J.

Patent number: 6297464Abstract: A microdevice reject handling system is provided for in a microdevice processing/feeder system. The feeder mechanism is immediately adjacent to the processing mechanism for receiving and moving microdevices away from the processing mechanism. It uses a conveyor which has a dead space in which microdevices cannot be placed by a robotic transport system, which moves microdevices from the processing mechanism to the feeder mechanism. The microdevice reject handling system is partially positioned in the feeder mechanism dead space for receiving rejected microdevices. It includes a reject bin with a storage portion for storing rejected microdevices beside the feeder mechanism and rests on a bracket containing an optical sensor system for determining when the storage portion is full.Type: GrantFiled: January 18, 2000Date of Patent: October 2, 2001Assignee: Data I/O CorporationInventors: Bryan D. Powell, Richard Alan Bernard, Lev M. Bolotin, Bradley Morris Johnson

Patent number: 6223098Abstract: A test control system for controlling overall test procedures which processes test data generated from the final test process and analyzes bin category results. The control system uses testers for testing electrical characteristics of IC devices, a host computer for processing data transmitted from the testers and for creating a number of database structures, and distributed computers for monitoring the test progress and analyzing the test results using the database structures stored in the host computer. A control method using the control system includes the steps of: performing a final test as a lot; monitoring the status of the final test progress while storing test data during the final test; determining if the final test is completed; performing a lot decision after the final test is completed based on bin category limits; and displaying the lot decision result and storing the test data.Type: GrantFiled: March 2, 2000Date of Patent: April 24, 2001Assignee: Samsung Electronics Co., Ltd.Inventors: Kwang Yung Cheong, Ann Seong Lee, Jae Young Kim
