Filed: 1993-05-19
Abstract: PURPOSE:To obtain a serial bus communication system capable of constituting a slave side only of logic circuits by putting a trigger pulse on the head of every bit cycle. CONSTITUTION:The communication of information is performed by a pulse width modulation between a master-side transmission system 2 having a master transmission logic 4 and a master reception logic 6 and a slave-side transmission system 3 having a slave transmission logic 18 and a slave reception logic 16. In this system, each transmission logic outputs a trigger pulse of 1/4 bit cycle width, for instance, on the head of every bit cycle of information to be transmitted and succeedingly puts data on the head. Each reception logic latches data when 1/2 bit cycle, for instance, passes after prescribed period passes from the front end of a trigger pulse. Thus, a slave side can be assembled only with logic circuits.

Filed: 1991-06-12
Abstract: PURPOSE:To remove Ga selectively from a liquid phase epitaxial wafer by immersing a liquid-phase epitaxial wafer with a protective film in an etchant to selectively remove the remaining Ga before etching the protective film away. CONSTITUTION:After epitaxial growth is performed on a GaAs wafer 1, Ga that has not wiped off remains on edges and central areas of the liquid-phase epitaxial surface 2b. SiO2 is sputtered over the wafer to form a protective film. The protective SiO2 is deposited on the normal epitaxial surface 2b, but not on the remaining liquid Ga 4. Therefore, only the remaining Ga can be etched away. The epitaxial wafer with the protective film is immersed in an etchant (HNO3:H2O=1:1) that is agitated for 5-10 minutes to remove the remaining Ga 4 only. Then, the protective film 3 is removed by etching in a mixture of NF and NH3F.

Title: Method and device for grinding wafer
Inventor: UEDA TETSUYA
IPC: B24B37/013
Filed: 1990-05-29
Abstract: PURPOSE:To enable precise, high-speed and easy execution of complete flattening of a substrate having indentation by a method wherein elements, dyestuff and chemical substances contained in an organic resist or silica glass are detected or analyzed by analyzing a grinding waste liquid, a point of completion of grinding is judged and the rotational speed, load pressure and load position of a grinder are controlled. CONSTITUTION:Grinding is conducted so that a load is applied uniformly on a rotary grinder 10, and thereby a resist 45 alone is removed. When the surface of an SiO2 film 44 appears, the rate of removal of the resist 45 lessens and therefore dyestuff detected from inside of the resist decreases sharply. The amount of the load is reduced in this stage and a method of applying the load uniformly is changed over to a method of applying the load in a way of displacement. The load is applied in the directions A, B, C and D for 30 seconds at this time, and the dyestuff of a grinding waste liquid flowing for 30 seconds is quantified. The result of this quantification is fed back to the amount of the load to be applied secondly in the directions A, B, C and D, and programming is made beforehand so that the load is applied more to a point at which the density of the dystuff is larger. By continuing this operation until the dyestuff is no longer detected in the grinding waste liquid, a completely flat plane is attained.
