    摘要: First, an insulating film is formed over the entire surface of a semiconductor substrate including a channel region for a field effect transistor. The insulating film has a gate electrode opening over the channel region. Next, a protective film is deposited over the entire surface of the insulating film. Then, a lower electrode, a capacitive insulating film and an upper electrode are formed in this order in a region on the protective film where a capacitor will be formed. Subsequently, part of the protective film, with which the gate electrode opening of the insulating film has been filled in, is removed, thereby exposing the semiconductor substrate within the gate electrode opening. And then a gate electrode is formed to fill in the gate electrode opening again.

    摘要: On a semi-insulating substrate is formed a conductive layer and an undoped layer. On specified regions of the conductive layer are formed ohmic electrodes, each serving as a source electrode or a drain electrode, via a pair of square contact regions. The circumferential edges of the contact regions are undercut beneath the ohmic electrodes. Between the pair of contact regions on the conductive layer is formed a gate electrode by self alignment using the ohmic electrodes as a mask. The gate electrode has extended in the direction of gate width and the extended portion serves as a withdrawn portion of the gate electrode. Upper electrodes are formed by self alignment in the same process in which the gate electrode is formed.

    摘要: A method consists of the steps of depositing a Ti--Pt metal film on a SiN layer insulation film mounted on GaAs substrate, etching the Ti--Pt metal film to form a first metal layer, depositing a SrTiO.sub.3 insulating film, etching the SrTiO.sub.3 insulating film to form an insulating film, depositing a WSiN metal film according to a sputtering technique while controlling a deposition pressure of nitrogenous gas, etching the WSiN metal film to simultaneously form a second metal layer on the insulating film and a thin metal film resistive element on the SiN layer insulation film, depositing a SiO.sub.2 passivation film, and making via holes. SrTiO.sub.3 has a high relative dielectric constant, and WSiN has a high melting point. Nitrogen atoms in WSiN prevent oxygen atoms in the insulating film from diffusing into the second metal layer. The adhesion of second metal film to the insulating film is tight because of the sputtering technique. The resistance of the thin metal film resistive element is stable because of nitrogen atoms strongly bonded to tungsten atoms and silicon atoms.
