Title: Manufacture of semiconductor integrated circuit
Inventor: IMAEDA YASUO
IPC: H01L21/331
Filed: 1987-07-22
Abstract: PURPOSE:To form an integrated circuit having two or more elements, whose depth positions of embedded layers are different by one-time epitaxial growing, by introducing impurities having the different diffusion coefficients into the specified position of a semiconductor substrate, and thereafter growing an epitaxial layer on the semiconductor substrate. CONSTITUTION:Two kinds of donor impurities having the different diffusion coefficients are introduced into two positions corresponding to succeeding elements in a p-type semiconductor substrate 20. Thus, two impurity introduced regions 21 and 22 are formed. Then, epitaxial growing is performed. Thus, an epitaxial layer 24 is formed on the semiconductor substrate 20. Then, a base region 25, an emitter region 26 and a collector region 27 are formed by thermal diffusion of specified impurities and the like. Acceptor impurities are diffused. Thus, an isolating region 23 is extended so as to penetrate the epitaxial layer 24. The impurities in the impurity introduced regions 21 and 22 are diffused into the epitaxial layer 24 again, and embedded layers 28 and 29 are formed. Thus, two kinds of the elements having the different effective thicknesses with respect to the epitaxial layer 24 can be formed at the same time based on the diffusion coefficients of two kinds of the impurities.

Abstract: PURPOSE:To hold the character level of characters displayed on a screen at the best level at all times by generating a character level having a constant level difference from a detected brightness signal level and holding the character level at its last level when the level of the brightness signal varies abruptly. CONSTITUTION:A brightness level detecting circuit 5 detects the level of the brightness signal S2 whose synchronizing head end part is put in order and sends out a level control signal S5 corresponding to the detected level to a character level generating circuit 3. The character level generating circuit 3 generates the best character level for making the character level and brightness signal level unequal according to the level control signal S5 from the brightness detecting circuit 5 and outputs its character level signal S7 to a character mixing circuit 2. If the level of the brigntness signal varies abruptly, a holding circuit 6 outputs a hold signal S6 to the character level generating circuit 3 to maintain and outputs the character level which is generated right before to the character mixing circuit 2.

Title: Measuring method for brightener density in plating solution
Inventor: KUDOU HIDEO
IPC: G01N21/31
Filed: 1981-11-16
Abstract: PURPOSE:To measure brigtener density in plating solution with high accuracy by obtaining absorbance difference between the absorbance of the filtrate which is filtered after mixing plating solution of a predetermined volume with activated charcoal added therewith and is measured at a specific wavelength and the absorbance of a predetermined volume of plating solution before adding the activated charcoal and is measured at a predetermined wavelength. CONSTITUTION:A predetermined volume of plating solution including such as copper pyrophosphate, potassium pyrophosphate, ammonia, wetting agent and brightener is added with activated charcoal powder at the ratio of 0.2g/200ml and then is mixed. The mixed fluid is filtered to get filtrate so as to measure absorbance characteristic of wavelength at 340-500nm on the basis of the atmosphere. A difference between the absorbance characteristics before and after the activated charcoal is added is obtained at the light of same wavelength. The amount of the brightener is accurately and readily measured by making an analytical curve in advance as the difference of absorbance is directly related with the density of the brightener. Thus, production of inferior goods is prevented by detecting excess and deficiency of the brightener thereby to prepare the  plating solution.
