Patent JP-H04186660-A (JP)
Title: Package for semiconductor device
Inventor: KAWAHARA YOSHITOKU
IPC: H01L23/50
Filed: 1990-11-16
Abstract: PURPOSE:To prevent solder from adhering to one part of a lead or prevent fellow solders, pushed out on the top of a wiring board, from shorting with each other by providing a degassing through hole for venting gas in the wiring board. CONSTITUTION:Though there is a through hole 3 for pin insertion at a wiring board 1A, besides a degassing through hole 15 for letting the gas generated in soldering go above the substrate is provided. The gas generated below the wiring substrate in soldering is vented above the wiring board through the degassing through hole 15, so the solder does not adhere to one part of the pin, or trouble vanishes such as that the fellow solders pushed out to the topside of the wiring board by boiling short with each other. For the degassing through hole, there is no necessity of providing a conductive film at the inner face, and a mere through hole will do, and the size may be smaller than the through hole for pin insertion.

Title: Thin film sample making method
Inventor: TAMEGAI HARUKO
IPC: G01B11/06
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To make a sample as thin as possible by mechanical grinding, by monitoring the thickness of a thin piece utilizing changes in interferring color when a thin film material is irradiated with light during the working of a sample into the thin piece in a mechanically grinding process. SOLUTION: A sample cut piece is made about 50μm in thickness by a planar coarse grinding and a planar mirror finished grinding in a mechanically grinding process. A bowl coarse grinding is performed to bring the thickness of the sample down to about 10μm until the color of light transmitted through the sample cut piece turns to orange from red as noted by a first monitor 71. Then, as the thin piece of the sample proceeds by a bowl mirror-finished grinding, the color of the light transmitted through a thin piece part monitored by the first monitor 71 changes to red, orange and yellow. When the color of the transmission light is orange, the color of the reflected light of the thin piece part monitored by a second monitor 72 turns to gray and then, changes to white and transparency.  When the color turns to the transparency from white, the color of the light transmitted through the thin piece part monitored by a third monitor 73 appears slightly and the interference color becomes clear with the progress of the thinning. In this stage, the bowl mirror finished grinding ends. By this method the preparation of a sample as thin as possible is made possible in the mechanically grinding process.

A Tr2 is turned OFF by setting an output port 2 to 0 to start the charging of the capacitor with a reference resistance 12 only. A CPU 1 reads from an input port 5 at each fixed time and when a value read is 0, the increment of a TIMCNT is expected. When a terminal voltage vc of the capacitor C exceeds a reference voltage Vth, with the inversion of a voltage comparator 7, the input port 5 is turned to 1 stop the increment of the TIMCNT. Then, the Tr1 is turned ON to enter a temperature measuring mode and a thermistor 11 is connected in parallel to the reference resistance 12 to perform a measurement as mentioned above. The ratio of separate counts is determined and multipled by RS to obtain a resistance value RT to be measured.
