Abstract: In a first embodiment, Tetraethyl Orthosilicate Si(OC2H5)4 is used at the process temperature of 650° C.±5° C. as film forming material, to decrease crystal defects occurring during deposition. In a second embodiment, annealing is carried out in sparse oxygen gas atmosphere after deposition, to mend crystal defects that occurred during deposition. In a third embodiment, initial temperature of the CVD device is kept at about 400° C., whereby the start of natural oxidation of the deposition surface is prevented and production circumstances of the semiconductor element is not deteriorated. Then, the CVD device is heated up to CVD temperature of about 750° C. or about 650° C., to deposit oxide.

Abstract: A method of fabricating a semiconductor device includes the steps of forming a first film of silicon nitride or silicon oxynitride on a polysilicon layer, forming a second film of silicon oxide on the first film by chemical vapor deposition, and oxygen-annealing the second film to form a tunnel oxide film. The presence of the silicon nitride or silicon oxynitride film enables an annealing process with a high oxidation capability to be used without oxidizing the polysilicon layer. The leakage of unwanted current through the tunnel oxide film can thereby be reduced, improving the data retention characteristics of devices such as flash memories.

Abstract: The present invention protects a thin wire connection from oscillation of a resin protecting an electronic circuit module from vibration, impact, and corrosion. An electronic control unit including an electronic circuit module in which a bare chip is mounted on a circuit board and a case for housing the module, is provided, wherein the case is filled with a potting gel to protect the module. The bare chip, including its wire connection to the circuit board, is sealed in advance with a gelatinous resin having thixotropy prior to hardening. The gelatinous substance cures to form a hardened inner layer which has a penetration that is lower than that of the filled potting gel after hardening, and functions to eliminate or substantially reduce the affect of viscoelastic oscillation of the outer layer on the bare chip and the wire connection.
