Title: On-site detecting method of peeling of thin film
Inventor: SATO AKINOBU
IPC: G01B7/06
Filed: 1990-01-09
Abstract: PURPOSE:To shorten a test time and to detect a micro-peeling and releasing phenome non precisely by measuring the frequency of a quartz resonator on which a thin film is formed, and detecting the peeling based on the change in frequency. CONSTITUTION:An oscillating circuit 2 oscillates a quartz resonator 1 on which various kinds of thin films are formed. A frequency counter 3 measures the oscillating fre quency. A frequency analyzing device 4 analyzes and records the frequency measured with the couter 3. When a material is attached on the resonator 1, the oscillating frequency is decreased in proportion to the attached amount of the material. The change in weight in nanogram order can be detected based on the frequency change. As a result, when the thin film is formed on the probe 1 and the thin film is peeled, the substantial attached amount is decreased, and the oscillating frequency is increased. The increase in oscillating frequency is a phenomenon which occurs when the material is desorbed even if peeling does not occur. Under the constant-temperature and humid ity conditions, the desorption phenomenon and the like progress slowly. Therefore, when the peeling phenomenon suddely occurs, the phenomenon can be seaprated from other phenomena. The peeling phenomenon can be detected based on the rapid increase in oscillating frequency of the resonator 1.

Title: Inverted logical circuit
Inventor: NAKAI MASANORI
IPC: H01L21/331
Filed: 1981-01-13
Abstract: PURPOSE: To perform high-speed switching operation without spoiling high integration by providing a transistor (TR) which emits an excessive carrier to its base circuit when an npn TR constituting an I 2 L is powered up.  
     CONSTITUTION: Between a power source VEE and a signal input terminal IN, a power-source TR2 which operates as a load and a constant current source is  provided. Then, the emitter of a TR3 is connected to the collector-side output  terminal of a TR1, and the base and collector of the TR3 are connected to the  terminal IN and a ground point GND. Consequently, when the TR1 is saturated,  a base current applied to the base of the TR1 and a small number of excessive carriers accumulated in an epitaxial layer n epi  right under the base of the TR1 are shunt to the collector of the TR1 by the TR3. Consequently, the effective current amplification factor of the TR1 decreases and a cut-off frequency increases, achieving high-speed switching operation.

Title: Interface circuit
Inventor: NAKAI MASANORI
IPC: H03K19/013
Filed: 1981-01-13
Abstract: PURPOSE:To transfer an input signal to the next stage without varying its duty, by shortening a storage time by decreasing the extent of the saturation of a transistor (TR) for an interface. CONSTITUTION:When a signal is supplied to the base circuit 14 of a TR1 at the output stage of a linear circuit 11, the TR1 turns on. Electric power from a power source VCC is supplied to the base of a TR2, constituting an interface circuit, with the TR1 OFF. Then, a signal which corresponds to the switching state of the TR1 is supplied to the base of the TR3 of an I<2>L circuit 13 and a signal from the circuit 11 is transferred to an output terminal. Consequently, when the TR2 is saturated, a TR5 is turned on to shunt the base current of the TR2 to a ground point, thereby decreasing the extent of the saturation of the TR2. Thus, the storage time of the TR2 is shortened to transfer the input signal to a trailing state without varying it duty.

Abstract: PURPOSE: To form a final passivation film of uniform quality on a semiconductor substrate by a method wherein a plasma CVD process is carried out bringing one of parallel electrodes into contact with the surface of an electrode layer formed on the peripheral surface of the semiconductor substrate where a film is formed. CONSTITUTION: In dummy chips 5, an oxide film 6 formed on the surface of a wafer 1 is removed in lines for the formation of dicing lines 31 and 32 on the wafer 1, and an Al-Si electrode 7 is brought into contact with a part of the exposed region of the wafer 1 where the dicing line is provided. A plasma CVD method is carried out through such a manner that the wafer 1 is placed on an upper electrode, with its surface where the Al-Si electrode 7 is exposed down. The Al-Si electrode 7 whose side face 71 comes into contact with the wafer 1 is brought into contact with the upper electrode, whereby the impedance between the wafer 1 and a lower electrode is lessened and becomes constant. As a result, a passivation film 8 formed on the top becomes large in thickness, and the processed wafers are reduced in thickness variation to ±3%.

Time T2=T1-Tc obtained by subtracting accelerating time Tc for etching the film due to the presence of the resist film from the time T1 is determined as etching time, and used as a reference for etching the film of one production unit. Thus, variation in side etching amount per each one production unit can be reduced.
