Title: Connector structure of electronic parts and connection thereof
Inventor: YAMAMOTO MICHIHIKO
IPC: H01L21/60
Filed: 1994-08-30
Abstract: PURPOSE: To allow connection of electronic parts with no breaking and to provide a bump electrode of the electronic parts with fine pitch irregularities CONSTITUTION: Fine irregularities are formed on the under surface of a bump electrode 9 of a semiconductor chip (electronic parts) 11. On the other hand, a bump electrode 25 of a wiring board (electronic parts) 21 is softer formed than the bump electrode 9 of the semiconductor chip 11. Therefore, when the bump electrode 9 of the semiconductor chip 11 is pressed on a bump electrode 25 of the wiring board 21, a raised part of the bump electrode 9 of the semiconductor chip 11 bites into the bump electrode 25 of the wiring board 21 so as to connect both bump electrodes 9, 25 due to an anchoring effect. As a result, both bump electrodes 9, 25 can be connected without heating the semiconductor chip 11 at high temperature. Accordingly, connection can be performed without breaking the semiconductor chip 11, and the bump electrode 9 can be provided with fine pitch irregularities.

Filed: 1989-09-04
Abstract: PURPOSE:To realize the sample-hold function by combining a detecting circuit detecting the crest value of the input waveform, a clipping circuit and a resetting circuit, and using the clipping function. CONSTITUTION:The detecting circuit 1 detects that the crest value of the input waveform (b) inputted through an arithmetic circuit 4 coincides at least with a previously decided boundary and is changed into the detecting operation. While a clip circuit 2, during the detecting operation of the detecting circuit 1, outputs the previously decided maximum value of the input waveform, the resetting circuit 3, during non-detecting operation of the detecting circuit 1, resets the clipping circuit 2 and makes the output to the zero level. Consequently, after clip and reset processing, the input waveform becomes waveform (c). Therefore, from the triangular wave of (a) the pulse waveform (c) is obtained, simultaneously by using this pulse waveform as the sample-hold waveform, and every time the triangular waveform (a) reaches the plus maximum value, a voice signal (d) can be sampled and held.
