IPC: H01L21/52
Filed: 1982-11-19
Abstract: PURPOSE:To join a semiconductor chip stably with high thermal efficiency by instantaneously heating only the necessary junction region of a lead frame by laser beams. CONSTITUTION:Laser beams 40 emitted from an oscillator 38 are reflected by a bender mirror 46 oscillated and driven 48 while being reflected by a bender mirror 42 and being condensed by a lens 44, and vibrated in the direction rectangular to a paper surface on the lead frame 22. The lead frame 22 is moved simultaneously in the direction rectangular to a beam vibration by the XY base of a frame feeder 36, and the desired junction region 50 is scanned and heated. The semiconductor chips 12 are moved by a junction head 20 and welded after heating. According to the constitution, since only the necessary region can be heated instantaneously and the utilization rate of heat is improved and beams are made to scan, a time lag is generated in solidification and a gas generated on melting is extruded in the direction of a scan, gas traps causing voids are reduced, and a stable junction is enabled.

Title: Microwave oscillator
Inventor: ITO KENJI
IPC: H03B5/18
Filed: 1989-08-04
Abstract: PURPOSE:To suppress spurious oscillation by connecting a FET to ground through a parallel circuit comprising a series resonance element and a sustenance element. CONSTITUTION:A parallel circuit 16 is connected to a drain terminal 6. A drain terminal 6 of a FET 3 is connected to ground similarly as a conventional constitution at a frequency fOSC by selecting an electric length of a 2nd microstrip line 9 to be nearly 90 deg. to obtain a required oscillation wave. On the other hand, the susceptance B' of a 3rd microstrip line 15 is set to be B+B'=0 at a resonance frequency fX in the undesired mode of a dielectric resonator 2, where B is the susceptance of the 2nd microstrip line 9. Thus, a voltage across the parallel circuit 16 is increased and acts like a negative feedback voltage with respect to an input voltage to a gate terminal 4 to cancel the reflection gain of the FET 3.

Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain the correspondence between coordinates of a faulty part and observation coordinates by forming marks for observation on a semiconductor wafer even after the wafer is diced into chips. SOLUTION: A mark pattern 502 of a reticle pattern is formed on a scribe line between chips. The reticle is repeatedly formed 10 to 50 times in a process of manufacturing a semiconductor.

In this manner, the coordinates of the mark of every process are managed. As coordinate management, the managed coordinates and those of a faulty part are matched in consideration of arrangement of chips on a wafer. The vertical direction in the center of the scribe line is set to a Y axis, the lateral direction is set to an X axis, and the crossing point of the X and Y axes is used as the origin of the chip.
