Abstract: PURPOSE:To improve insulation between a metal plate and a wiring pattern and to prevent the generation of poor short circuit, by boring a through-hole through the metal plate from the side opposite to a side of lamination of an insulating layer and a copper foil. CONSTITUTION:A single-copper-clad laminated plate 8 has a structure that a metal foil 11 is laminated on one side of a metal plate 9 via an insulating layer 10. A through-hole 12 is bored by, for example, a driller through two laminated plates 8 from side B opposite to lamination side A. Next, these laminated plates 8 undergo heat and press moldings with a prepreg 13 interposed between the B side counter gap. This step allows the resin of prepreg 13 to run into a through-hole 12 of the metal plate 9 to fill it with the result that this resin forms the later insulating layer between the metal plate 9 and a through-hole. Thereafter, a through-hole almost coaxial with the through-hole 12 and smaller than it in diameter is formed, and this through-hole is plated to form a circuit pattern.

IPC: H01L21/324
Filed: 1989-09-23
Abstract: PURPOSE:To simultaneously form a semiconductor thin film having large particle size little defect in the particle uniformly over a large area in a short time by primarily heat-treating an amorphous semiconductor thin film at a temperature of 60% or less of melting point of semiconductor for 10 hours or more and then secondarily heat-treating it at a temperature of 85% or more of the melting point of the semiconductor. CONSTITUTION:When a semiconductor amorphous thin film is primarily heat- treated at 700 deg.C (60% of its melting point) or lower for 10 hours or more, nucleus forming speed in a solid state is reduced, and large grain size dendrite having micron size of maximum grain size is grown. Then, when it is heat- treated at 1200 deg.C (85% of its melting point), defects in grains of the crystal are reduced without varying the grain size grown by the primary heat treatment, and device characteristics are improved. Thus, a semiconductor thin film having no defect in grains of large grain size can simultaneously be formed uniformly over a large area in a short time.
