Title: Measuring method for thermal resistance of semiconductor device
Inventor: UENO TOSHIO
IPC: G01R31/26
Filed: 1991-11-27
Abstract: PURPOSE:To safely measure the thermal resistance from the difference of measuring values of voltages between two terminals, heating power and temperature coefficient of the voltages by supplying a predetermined testing current before and after a saturation current is fed to a semiconductor for a predetermined time to heat the semiconductor and measuring the voltages between the two terminals. CONSTITUTION:Through the manipulation of a switch 83, a measurement control circuit 80 turns a switch 31 of a direct current source 30 ON, and feeds a testing current between a collector and an emitter of a semiconductor device 1. A voltage detecting circuit 60 measures the voltage between a gate and the emitter, and the data is stored in the circuit 80 as a first measuring value. Then, the circuit 80 turns ON a switch 41, and supplies a heating current corresponding to the saturation current to the device 1. After finishing the heating process, the circuit 80 cuts the heating current, entering a second measuring process, where a second measuring value is stored in the circuit 80 in the same procedure as above. Thereafter, the thermal resistance is promptly calculated from the difference of the first and second measuring values, heating power, and temperature coefficient specific to the voltage between the gate and emitter of the device 1. Accordingly, it is possible to measure the thermal resistance without a fear of damage due to the oscillation.

Title: Bonder and bonding method
Inventor: SHIBATA MOTOJIRO
IPC: H01L21/60
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To prevent flow-out of solder material and rapture after solidification by correcting the shift of holding height at a semiconductor device holding part due to thermal shrinkage of solder material at the time of bonding the semiconductor device to a mounting board. SOLUTION: A bonder for soldering a semiconductor device to a mounting board is provided with a part 4 for holding the semiconductor device 1 oppositely to the mounting board 13 through a, solder material 2. Expansion/contraction of the holding part 4 is detected by an expansion/contraction detecting means 22 at the time of heating or cooling the solder material 2. Based on the detected value, holding height of the semiconductor device 1 is corrected at the time of heating or cooling the solder material 2. Consequently, the height of semiconductor chip 1, i.e., the distance between semiconductor chip 1 and mounting board 13, is sustained at a desired value depending on the heating/cooling of solder 2 during bonding process. This method can prevent a molten bump 2 from flowing to other place and can protect a solder bump 2 against rupture at the time of solidification.

Title: Radio selective call receiver with intermittent reception function
Inventor: KIDO TORU
IPC: H04B1/16
Filed: 1994-12-16
Abstract: PURPOSE: To settle the synchronous state immediately at the time of power-on by receiving receiver's own call number to report the call and performing intermittent reception in a reception part for improvement of the battery saving efficiency and setting the radio part turning-on time to shorter at the time of failing to detect a synchronizing signal. CONSTITUTION: When a synchronous detection signal is inputted to a battery saving signal generation part 12, this part 12 settles the state of synchronization with a digital signal. The battery saving signal generation part 12 outputs the battery saving signal which turns on/off a radio part 2 at a specific timing until the state of synchronization with the digital signal is settled. Meanwhile, the battery saving signal generation part 12 outputs the battery saving signal which turns on/off the radio part 2 at the timing of reception of the preliminarily determined batch including receivers' own call number after the state of synchronization with the digital signal is settled. Thus, the synchronizing signal can be received by the first start up of the radio part.
