Title: Manufacturing method of semiconductor device and semiconductor device thereby manufactured
Inventor: KIKUCHI HIROSHI
IPC: H01L21/60
Filed: 1992-01-27
Abstract: PURPOSE:To form a resist for bump-plating on the whole wafer surface in one process, thereby to remarkably simplify the formation of the connector bump of a semiconductor device. CONSTITUTION:An electrodeposition bath 1 is filled with an electrodeposition type photoresist solution 2, and a direct current power source 3 and a counter electrode 4 are prepared. A wafer 6 having a barrier metal film 5 formed on the element surface thereof is dipped in the resist solution 2, and a voltage and current is applied through a connecting wires 7. By such treatment, the whole surface of the wafer 6 is coated with a photoresist layer 8 of a fixed thickness. This is used as a plating resist to form a bump on the wafer 6 and to fabricate package such as TAB. This allows a high precision bump to be made very easily on the wafer 6, whereby a semiconductor device can be provided in far fewer processes than conventional methods.

IPC: H01L21/027
Filed: 1984-01-27
Abstract: PURPOSE:To control optionally the sensitivity of a resist and to form efficiently and rapidly a high-precision resist pattern, by cooling fast a baked resist using cooling liquid while the space filled with the cooling liquid is kept under a specified pressure, after it is cooled to desired temperature gradually. CONSTITUTION:A resist film is coated over a substrate to be treated, is then pre-baked and normally cooled. After a desired pattern is exposed to the resist film, the resist film is bakded at predetermined temperature Tb above the glass transition temperature Tg of the resist (baking before developing). After the baking before developing, a first cooling with which the temperature of the substrate with the resist film (i.e., the temperature of the resist film) is decreased from the baking temperature Tb to a given intermediate cooling temperature Tm (Tb>=Tm) is done. Next, under a pressurized state whose boiling point is in excess of Tm, a second cooling with which the temperature is decreased from the intermediate cooling temperature Tm to a final cooling temperature Tc (Tm>Tc) is done rapidly and uniformly, by immersing rapidly the entire substrate into a liquid coolant having the final cooling temperature Tc.

Filed: 1982-01-29
Abstract: PURPOSE:To realize the high accuracy etching of a selective oxidation mask, the shortening of selective oxidation time and the reduction of bird beaks, by performing a pre-treatment before a selective oxidation. CONSTITUTION:An SiO2 film 2 is formed on a semiconductor substrate 1, thereafter an Si3N4 film 3 is formed, and then a photoresist pattern 4 is formed at a fixed region. Next, neutral ions such as Ar are implanted into the substrate 1 at the energy whereby they reach the substrate 1. Where, the numeral 5 represents the Ar implanted Si3N4 film, and the numeral 6 represents the Ar implanted substrate. Then, the film 5 is etched. Since this film 5 gets the etching rate increased by a neutral ion implantation, a good etching with small side etch is performed. While P is introduced into a P channel region, and B is introduced into an N channel, thus a channel stopper 7 is introduced into the part wherein the Si3N4 film is etched. After removing the resist, an oxide film 8 is formed. Thereat, the oxidation rate of the Ar implanted part becomes larger than that of a normal substrate by several times, and accordingly the shortening, etc. of oxidation time are enabled.

Title: Semiconductor memory device
Inventor: TOYAMA TAKESHI
IPC: G11C11/413
Filed: 1987-01-22
Abstract: PURPOSE:To absorb noise and to improve the operational stability by connecting the drain of a two-layered gate transistor having a floating gate to the gate of input transistor of high voltage level identification circuit and earthing the gate of said transistor and a source. CONSTITUTION:The gate and source of a transistor 8 having a two-layered gate structure attached with a floating gate are earthed and its drain is connected to the gates of transistors 2, 4. When a pad 7 is impressed with a voltage, the potential at a node C shows a tendency of saturation from the point when a potential is induced on the floating gate by the voltage impressed on the drain of the transistor 8 to start the leakage. As a result, the input level to the subsequent step of an inverter 11 for identifying the high voltage level is reduced. Thus, even when the noise of about 10V is inputted, the identification circuit of the high voltage level is not reacted so as to prevent the malfunction and to obtain the stable response.
