Title: Epitaxial growth method
Inventor: MORITA HISASHI
IPC: H01L21/205
Filed: 1985-07-24
Abstract: PURPOSE:To prevent reduction in production yield and deterioration in characteristics and autodoping from occurring on the back surface, by making impurities, which diffuse over the back surface of a semiconductor substrate, stay inside a diffusion-preventive film and then performing epitaxial growth. CONSTITUTION:When SiO2 films 2 and 3 are formed on a Si substrate 1, and patterning is performed to form embedded diffusion layers 5 on the surface by forming diffusion windows 4 on the SiO2 film 2, the whole back surface is coated with resist for etching to make the oxide film, SiO2 film 3, remain on the back surface. Thus, in case that embedded layer impurities are devo- diffused, the impurities stay inside the SiO2 film 3 and never diffuse into the substrate 1. Followingly, by removing the oxide films 2 and 3 on the respective front and back surfaces, the embedded diffusion layers 5 having desirable patterns are formed, and autodoping can be prevented from occurring at the back surface when epitaxial growth is performed by an ordinary method. Because of only processing the back surface before forming the embedded diffusion layers, the surface can be prevented from being damaged and contaminated, and without excessive thermal process after forming the embedded diffusion layers, deterioration in characteristics can be avoided.

Title: Level shift circuit
Inventor: SUYAMA KATSUHIKO
IPC: H03K5/003
Filed: 1978-12-23
Abstract: PURPOSE:To stabilize the operation of a level shift circuit easily by making the saturation current value of a diode much greater than the constant current of constant-current supply FET by decreasing the width or thickness of a semiconductor layer constituting the diode less than those of two FETs. CONSTITUTION:As a constant-current supply, FET2 serves, and FET1 operates as a source follower with loads of FET2 and diode 3. An input voltage applied to the gate of FET1 is level-shifted by a voltage drip across diode 3 and then outputted from a series-connection point between diode 3 and FET2. In this case, the width or thickness of a semiconductor layer constituting diode 3 is decreased less than those of FETs 1 and 2 to fix the saturation current value of diode 3 much greater than the constant-current value of FET2. Consequently, the operation of a level shift circuit can be stabilized in an extremely-easy method.
