    摘要: First, a low-concentration impurity layer is formed by obliquely implanting an n-type impurity at a prescribed angle with respect to the surface of a p-type semiconductor substrate, using a gate electrode formed on the semiconductor substrate as a mask. Thereafter a sidewall spacer is formed on the sidewall of the gate electrode, and then a medium-concentration impurity layer is formed by obliquely implanting an n-type impurity to the surface of the semiconductor substrate. Thereafter a high-concentration impurity layer is formed by substantially perpendicularly implanting an n-type impurity with respect to the surface of the semiconductor substrate. According to this method, the low-concentration impurity layer in source and drain regions having triple diffusion structures can be accurately overlapped with the gate electrode, with no requirement for heat treatment for thermal diffusion.

    摘要: A semiconductor device comprising a substrate having a hollow cavity for mounting a semiconductor element therein and a lowered step surface at a periphery of the cavity for mounting a chip component thereon. A semiconductor element is mounted within the cavity and a chip capacitor is mounted to the lowered step surface. The semiconductor element and the chip component are adapted to be connected to an external circuit through electrical conductors. A cap is attached to the substrate and a seal material is filled into a space defined between the cap and the substrate for sealing the cavity and for encapsulating the chip component on the lowered step surface which may extend along the entire periphery of the cavity. The cap may include a projection adapted to abut gainst a side wall of the lowered step surface, or alternatively, the lowered step surface may include a side wall having a projection adapted to abut against periphery of the cap. The semiconductor device may further comprise a heat sink attached to the semiconductor element.

    摘要: A packaged semiconductor device includes a semiconductor element for receiving light, a semiconductor package containing the semiconductor element and including leads, optical glass sealing the semiconductor package and protecting the semiconductor element, the optical glass transmitting light and including an element that absorbs high energy radiation. Therefore, radiation such as gamma rays is absorbed by the anti-radiation glass and deterioration of the internal semiconductor element is prevented. A metal frame including a heavy metal radiation shield is provided at the periphery of the antiradiation glass. Thus, scattering of light in the semiconductor package is prevented and the positional deviation of the anti-radiation glass in the semiconductor package is prevented.
