Title: Substrate potential rise detecting method for bipolar ic
Inventor: HORIGUCHI KENJI
IPC: H01L21/822
Filed: 1988-12-22
Abstract: PURPOSE:To detect the rise of substrate potential by a method wherein the emitter of an NPN transistor is grounded independently of a bipolar IC for potential detection, a resistor to which the emitter of a PNP transistor is joined is connected with a bias power supply via a resistor for voltage level detection, and the voltage drop level of the resistor for voltage level detection is detected. CONSTITUTION:A thyristor circuit composed of the following is formed; an NPN transistor N1, and a PNP transistor P1 whose emitter is connected with the collector via a resistor REP1. The emitter of the NPN transistor N1 is connected with ground E independent of a substrate potential. The connection point between the resistor REP1 and the emitter of the PNP transistor P1 is connected with a bias power supply VCC via a resistor RS for voltage level detection. Thus, a voltage level detecting circuit is connected to the connection point between the transistor P1 and the resistor RS, and the thyristor circuit operates by the increase of a substrate potential. Based on this circuit, the rise of substrate potential and its degree can be detected by voltage level generating across the resistor RS. Thereby, the rise of substrate potential can surely be detected.

IPC: H01L23/50
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To improve solder wettability at the time of board mounting and reliability/productivity by activating a plating surface by jetting abrasive cleaner against the surface in dry air after an outer lead has been plated. SOLUTION: A lead frame 101 supplied from a loader 102 moves on a carrying rail 103. Oxidation/contamination/mechanical stress layers of a plating surface of the upper surface are eliminated, and activation is performed by using media jetted from an upper side nozzle 104. A plating surface on the opposite side is also activated by using a lower side nozzle 105. After air blow for preventing the media from being left, discharge is performed by using an unloader 106. By the above series of processes, an oxide film and a contamination layer on the platting surface of the lead frame 101 are eliminated, and an active plating surface can be obtained. Since oxidation and mechanical stresses in the processes after plating are physically eliminated, the plating surface of a semiconductor device becomes clean and smooth. As a result, the contribution to improvement of wetability is realized.

Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve user's convenience by an incoming side terminal returning a response signal when the name of a sent signal coincides with the name of own terminal and returning a communication rejection signal if it does not coincide with the name of own terminal. SOLUTION: A registration executing part 2-0 of each terminal registers own address and name to a name server NS and an address solving part 2-3 acquires address information from names of other terminals. A communication controlling part 2-1 of a sending end terminal sends a connection request signal which includes the address and name of an incoming side terminal to an incoming side terminal through a routing node when communication is established. A communication controlling part 2-1 of the incoming side terminal returns a response signal to the sending end terminal and continues communication if own name is included in the connection request signal. It returns a communication rejection signal to the sending end terminal and rejects communication if the self-name is not included.  The routing node notifies the sending end terminal of the effect if a terminal which corresponds to an address included in the connection request signal does not exist.

Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which can stably operate by effectively suppressing power supply ground noise in a high frequency domain. SOLUTION: One electrode of a by-pass capacitor 60 for absorbing noise is connected to power supply wiring VDD 40 and the other electrode is connected to a semiconductor substrate 20 and biased to the potential at the substrate 20 through the substrate 20. Accordingly, the residual inductance accompanying the other electrode of the capacitor 60 becomes smaller. Consequently, the frequency domain not accompanied by resonance phenomena is expanded and the noise in a high frequency domain is suppressed, because the resonance frequency of an LC serial resonance circuit formed of the capacitor 60 and the residual inductance accompanying the electrode of the capacitor 60 shifts to the higher side.
