Publication number: 20080111252Abstract: In accordance with the invention, a bump is formed on top of a die bond pad by forming a ball bond there. Then, without severing the wire, the capillary undergoes a set of coordinated motions to fold the wire on top of the ball bond. The wire is then bonded on top of the ball bond bump without severing the wire. This is then followed by a further set of coordinated xy motions to from the loop and bring the capillary over the second bond site (e.g., on the lead frame). The wire is then stitch bonded to the second bond site and the tail severed to complete the wire loop interconnect.Type: ApplicationFiled: November 20, 2007Publication date: May 15, 2008Applicant: KULICKE AND SOFFA INDUSTRIES, INC.Inventors: Ivy W.

Publication number: 20030028281Abstract: A stir-friction hot-working or welding arrangement uses a pin tool having a ligament 22 and a shoulder 224. The force required for incremental penetration increases markedly when the shoulder is reached.

Patent number: 6456899Abstract: Automatic detection of defects during the fabrication of semiconductor wafers is largely automated, but the classification of those defects is still performed manually by technicians. This invention includes novel digital image analysis techniques that generate unique feature vector descriptions of semiconductor defects as well as classifiers that use these descriptions to automatically categorize the defects into one of a set of pre-defined classes. Feature extraction techniques based on multiple-focus images, multiple-defect mask images, and segmented semiconductor wafer images are used to create unique feature-based descriptions of the semiconductor defects. These feature-based defect descriptions are subsequently classified by a defect classifier into categories that depend on defect characteristics and defect contextual information, that is, the semiconductor process layer(s) with which the defect comes in contact.Type: GrantFiled: December 7, 1999Date of Patent: September 24, 2002Assignee: UT-Battelle, LLCInventors: Shaun S.

Publication number: 20010016786Abstract: So as to achieve accurate detection of the bonding tool position in, for instance, a wire bonding apparatus, the positional relationship between a position detection camera and a reference hole formed in, for instance, a clamper is measured by imaging the reference hole by the position detection camera. The position detection camera and a bonding tool are moved by an XY table, and the tip end of the bonding tool is inserted into the reference hole. Then, the bonding tool is moved in the X and Y directions, and the contact of the bonding tool to an edge of the reference hole is detected based upon changes in the waveform of the ultrasonic vibrations applied to the bonding tool, thus measuring the positional relationship between the tool and the reference hole. The offset amount between the position detection camera and the bonding tool is then determined based upon the measured values and the amounts of movement of the bonding tool between the locations for such measured values.Type: ApplicationFiled: February 12, 2001Publication date: August 23, 2001Applicant: KABUSHIKI KAISHA SHINKAWAInventors: Kuniyuki Takahashi, Shinji Maki

Patent number: 6085122Abstract: A selective laser sintering apparatus and method is disclosed, in which the laser power is controlled according to the scan velocity. The scanning system, which includes a pair of galvanometer-controlled mirrors for directing the aim of the laser beam, generates signals indicative of either the position or scan velocity of the aim of the beam, in either one or two directions. The signals are gated in the laser power control system so as to pass the signals only during those times at which the laser is to be turned on. A laser power control system receives the signals and, in the case of position signals, differentiates the signals to generate velocity signals. The velocity signals are used to derive a scan velocity, and the scan velocity is multiplied by the desired laser power at full scan velocity to produce a laser power control signal.Type: GrantFiled: May 30, 1997Date of Patent: July 4, 2000Assignee: DTM CorporationInventor: Gerald L.
