Title: Semiconductor device
Inventor: HAYAKAWA TOSHIRO
IPC: H01L21/205
Filed: 1987-11-12
Abstract: PURPOSE:To form a semiconductor device where its threshold electric current is small and its efficiency is high, by tilting the face direction of a semiconductor from the principal face direction of crystal faces in the case of the semiconductor device where a compound semiconductor layer containing In and Al on the semiconductor substrate is formed by making its layer perform a vacuum epitaxial growth. CONSTITUTION:The growth face direction of a semiconductor substrate 1 is formed by tilting it at the range of 0.5 deg.-10 deg. from the principal face direction of crystal faces. The substrate where its face direction is tilted in such a manner is formed by the following process: a stepped terrace structure is formed at the crystal surface of the GaAs substrate 1 which is formed by tilting the face direction after having a (100) face as the principal face; in a crystal growth process, when atoms flown onto the substrate 1 perform migration at the flat part 3 of the terrace structure to the utmost L, the atoms are taken in by a kink site 4 to perform a crystal growth. That is to say, a migration length of the flown atoms on the surface of the substrate 1 having the terrace structure is controlled by the flat part length L of the terrace structure. In an epitaxial crystal growth process of a compound semiconductor layer containing In and Al, the flat part length L of the terrace structure is established based on each Al atom 5 having a short migration length.

Title: Output circuit
Inventor: MIYAJI FUMIO
IPC: H03K19/094
Filed: 1985-12-20
Abstract: PURPOSE:To attain high speed and low noise by adopting the constitution of 3-stage of changeover for a gate potential of an N-MOS transistor (TR) in an output circuit of complementary operation. CONSTITUTION:An N-MOS TR 3 is turned from ON to OFF and an N-MOS TR 5 is turned from OFF to ON in the process that a data potential inputted from a terminal 16 changes from an L level to an H level, a gate potential of an N-MOS TR 4 goes to a middle potential and the N-MOS TR 4 is conductive, its conductance is not maximized and since the discharge time constant of a load capacitance 14 is large, an output terminal voltage V0 falls down gradually. Then a NAND 13 and inverters 9, 10 act like a delay circuit, a potential at a point B reaches an L level with a delay, then a P-MOS TR 2 is turned on, the potential at a point A rises to an H level from an intermediate potential, the conductance of the N-MOS 4 is maximized and the output terminal voltage V0 decreases quickly. Since the decrease in the voltage V0 is a decrease from the intermediate output voltage, the effect onto a GND level is suppressed and no malfunction is caused even when the entire operation is quickened.
