Title: Mis type transistor and manufacture thereof
Inventor: KOMATSU YUJI
IPC: H01L27/092
Filed: 1995-06-12
Abstract: PURPOSE: To compensate the drop of threshold voltage caused by short-channel effect by a method wherein a gate electrode, having the distribution of work function in gate length direction, is formed on the gate insulating film formed on the surface of a semiconductor substrate. CONSTITUTION: A gate oxide film 3 is formed on the surface of the active region prescribed by an element isolation region 2 on a silicon board 1, and a composite type gate electrode 4 is formed. Conductive materials A and B, having different work functions, are arranged in series in longitudinal direction of a gate electrode on the gate electrode 4. When the gate length is sufficiently long, the work function of the gate electrode 4 is almost determined by the work function of the conductive material A. The contribution of the conductive material B increses as the gate length becomes shorter, and threshold voltage boosts. Also, the gate length when the threshold voltage suddenly begins to drop becomes shorter than the case where the gates electrode is formed by the conductive material A only.  As a result, the range of design of the gate length, on which the specific threshold voltage can be compensatied, can be increased.

Title: Semiconductor integrated circuit in high-frequency band
Inventor: KANAZAWA KUNIHIKO
IPC: H01P3/08
Filed: 1989-06-09
Abstract: PURPOSE:To reduce significantly the area of a chip by a method wherein a dielectric layer having a relative dielectric constant larger than that of a semiconductor substrate is formed on a wiring metal film constituting a circuit on the substrate. CONSTITUTION:A wiring metal film 2 is formed on a semiconductor substrate 1, an insulating film is normally provided between the substrate 1 and the metal film 2 and a protective film is formed on the metal film 2. A dielectric layer 6 of a relative dielectric constant larger than that of the substrate 1 is laminated on a monolithic microwave IC (an MMIC) formed in such a way with a bonding agent 7. If a dielectric layer of a relative dielectric constant of 70 to 100 or thereabouts of the relative dielectric constant of the dielectric layer 6 is formed, the wavelength of a high frequency on the metal film 2 becomes 1/epsiloneff<-2> times by the relative dielectric constant epsiloneff of the dielectric layer at this time. Therefore, the wavelength becomes 1/3 thereabouts of that on the GaAs substrate 1 and the area of a chip results in being reduced to 1/10. The larger the ratio of the thickness of the substrate 1 to the thickness of the dielectric layer 6 is, the larger the ratio of the relative dielectric constant of the substrate to that of the dielectric layer becomes and the effect can be increased.
