Title: Semiconductor package
Inventor: GOTO AKIO
IPC: H01L23/50
Filed: 1990-04-19
Abstract: PURPOSE:To prevent an increase in the number of steps and an increase in a manufacturing cost and to obtain a solder bonding of high reliability by forming leads of shape memory alloy to be deformed in a normal shape based on heating at the time of soldering. CONSTITUTION:A plurality of leads 6A to be arranged at the side of a body 4 and mounted at a land 2 through solders 5 are provided. The leads 6A are all formed of shape memory alloy. If they are deformed to a floating lead 7, a bent lead 8, they are so deformed to a normal shape based on heating at the time of soldering. Accordingly, when the leads 6A are mounted on a board 2 of a semiconductor package 3, even if the lead 6A is deformed to the lead 7 as indicated by a broken line, it is deformed to the normal shape on the way of heating at the time of soldering due to the characteristics of the shape memory alloy of the lead 7 and soldered. Accordingly, solder bonding of mechanically and electrically high reliability is performed irrespective of the presence or absence of the deformation of the lead 6A.

Filed: 1987-04-30
Abstract: PURPOSE:To remove completely flicker caused by the interference of both the driving frequences of a back light and a display cell by giving a prescribed relation between both said frequences. CONSTITUTION:The driving frequency f2 of a cell 10 is increased to the frequency of 700Hz which corresponds to 14 times of 50Hz by a multiplier 18, and the back light 16 is drived by an amplifier 20 provided with a brightness control means 19. When the driving frequency f1 of the cell 10 is fixed to 50Hz, in order to make the strength of the flicker to zero, the driving frequency is included in a range except the range of (nf2-20)Hz<=f1<=(nf2-1)Hz and (nf2+1)Hz<=f1<=(nf2+20)Hz (n is natural number). Thus, as the driving frequency f1 of the back light 16 is an integer (n=14), the flicker caused by the interference of both the frequences f1 and f2 is zero, thereby remarkably improving the display quality of the titled device.

Abstract: PURPOSE:To facilitate a detection of a faulty area, by switching the using system to a stand-by system when the using system has a fault and at the same time reporting the system switcing to a monitor device above that time through a receiving station or a transmitting system. CONSTITUTION:For instance, a data transmitting device 2 receives a data frame and performs an FCS check when data is transmitted to the device 2 from a data transmitting device 4. Then no answer frame is sent back to the device 4 if an error of the data frame is detected. The device 4 detects the time-out if no answer frame is sent back and then transmits again the same data frame. When the error detecting frequency through the FCS checking exceeds a prescribed level, the device 2 regards that the using system is not serviceable and then switches the using system to a stand-by system as well as to inform this switching to a monitor device 1. On the other hand, the device 4 decides the failure of retransmission and then informs this fact to the device 1 by means of an information field I.

Abstract: PURPOSE:To enable the micro formation of elements by markedly reducing the area of the second film after oxidation by a method wherein an impurity layer is formed in self-alignment to the second film after oxidation, thus markedly reducing the second film in thickness of the part positioned on the side wall of the first film. CONSTITUTION:An n<+> type buried layer 2 and an n type epitaxial grown layer 3 are formed in a p type Si substrate 1. A film 21 of three-layer structure is constructed by forming an SiO2 film 4, Si3N4 film 5, and SiO2 film 20. An SiO2 film 22 is formed on the surface of a polycrystalline Si film 8, and a p type impurity is ion-implanted over the whole surface. The polycrystalline Si film 8a on the side wall of the first film 21 is protected with the film 22 and is not doped with boron. After the film 22 is etched away, the film 8 is etched, and the film 8a not doped with boron is selectively etched away. This manner can markedly reduce the interval between the impurity layer and the second film and the area of the second film and thus enables the micro-formation of elements.
