IPC: H01L23/31
Filed: 1989-06-20
Abstract: PURPOSE:To reduce sharply the number of occurrences of resin cracks by forming a polyimide resin film of a specified thickness both on the surface of a semiconductor element and on the reverse surface of an island part of a lead frame. CONSTITUTION:Polyimide resin having excellent adhesion both to sealing resin and a semiconductor element and to the sealing resin and a lead frame is used. It the adhesion is not excellent, peeling occurs on an interface due to a steam pressure, a stress is concentrated thereon and consequently a resin crack occurs. A polyimide resin film is formed by coating both the surface of the semiconductor element and the reverse surface of an island part of the lead frame. If the surface of the semiconductor element alone is coated, peeling occurs on the interface between the reverse surface of the island part and the sealing resin, the stress is concentrated thereon and consequently the resin crack occurs. If the surface of the island part alone is coated, the peeling occurs on the interface between the surface of the peeling semiconductor element and the sealing resin, the stress is concentrated thereon, the resin crack occurs, and thus a sufficient effect can not be obtained. As to the amount of coating, the film having a thickness 5 to 100mum is formed on the surface of the semiconductor element and the reverse surface of the island part of the lead frame. As materials for the polyimide resin, tetracarboxylic-di-anhydride and diamine are used.

Abstract: PURPOSE:To obtain the good-quality thin film without exposing a substrate to plasma directly by arranging an activated gas generating device which is separated away from the position where a substrate is arranged in a vacuum chamber. CONSTITUTION:A compound gas including Si as an element composing a thin film, e.g., (SiH4) is introduced to an activated gas generating device 11 and a high-frequency voltage is applied to electrodes 12 and 13 for generating plasma. The silane gas is decomposed by plasma and activated molecular seeds (SiH)*, (SiH2)*, (Si)*, ions (SiH)<+>, (SiH2)<+>, and electrons are generated. These molecular seeds and etc. are spouted by a pressure difference to a substrate 2 by modulating conductances of a vacuum pump 4 and a slit 14 so as to make a degree of vacuum of a vacuum chamber 1 two or three digits lower than that of the activated gas generating device 11. The ions and electrons out of the activated gas spouted from the slit 14 are removed by an electrode 17. Consequently, a damage of the thin film caused by ion spattering can be removed.
