Patent JP-S5914906-B2 (JP)
IPC: H01L21/338
Filed: 1979-10-25
Abstract: PURPOSE:To eliminate the need for a wire for connecting electrodes of a field effect transistor and improve its radiating efficiency by making a concave portion for forming a main electrode in the upper surface of a semiconductor substrate and allowing the electrode provided in the concave portion to directly contact with a plated heat sink provided on the substrate lower surface. CONSTITUTION:A concave portion 9 is made in an N type layer 2 on a semiinsulative substrate 1, extending into the substrate 1. The layer 2 is etched so as to leave only a portion of it extending over one of the edges of the concave portion 9 and the central portion of the substrate 1. Then a source electrode 3 is formed covering the side walls and bottom of the concave portion 9 and extending on the end of the remaining layer 2, and a gate electrode 5 and a drain electrode 4 are provided on the layer 2. After that, with only the circumference left, the lower surface of the substrate 1 is etched to allow the electrode 3 at the bottom of the concave portion 9 to be exposed, and the whole lower surface of the substrate 1 is coated with a metal layer 10 so that it contacts with the electrode 3. Then a resist layer 11 is provided on the circumference of the substrate lower surface, and a plated heat sink 12 is secured through a plated layer 14 to the layer 10 surrounded with the resist layer 11. Thus, the sink is used also as an electrode material.

Abstract: A film carrier comprising, on a laminate of an insulating layer and a conductive circuit, a conductive part to be connected to an external substrate and an energy introduction part to supply an energy to connect a semiconductor element, a semiconductor device, and a method for mounting a semiconductor element. The present invention has enabled provision of fine-pitched or highly dense wiring of a semiconductor element, and assures easy and dependable electric connection of a film carrier to a semiconductor element. The construction of the present invention wherein an energy for connection is supplied from the energy introduction part to make a connection of a film carrier to semiconductor element is advantageous in that attenuation of the energy for connection due to an insulating layer occurs less, since the energy for connection can be directly introduced into conductive circuit, thus enabling efficient utilization of the energy, which in turn permits easy and efficient mounting of a semiconductor element. <IMAGE>

IPC: B29C45/26
Filed: 1981-10-30
Abstract: A hot sprue assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The hot sprue assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The hot sprue assembly includes a hot sprue bushing cooperating with a dispersion head to define an open and relatively narrow annular gate through which molten material is injected into the mold cavity, and a central die plug within the mold cavity for cooperating with the dispersion head to mold a central aperture into the disc. Valving of the molten material through the gate is achieved by heating the sprue assembly to create a temperature differential which, during soldification of the material within the mold cavity, permits the material within the mold cavity to soldify up to the gate without substantial soldification of material within the sprue assembly. The gate is disposed at a plane recessed slightly from the general plane of the soldified disc to prevent any surface discontinuities arising by retraction of the sprue assembly when the mold cavity is opened from projecting above the general plane of the disc.
