Title: Semiconductor pellet
Inventor: SUZUKI KOICHI
IPC: H01L21/02
Filed: 1988-04-05
Abstract: PURPOSE:To obtain a semiconductor pellet having a structure wherein cracks are not formed due to resin shrinking stress at the time of resin sealing, by providing a hill-shaped step part higher than an inner periphery at a part or the entire part of the outer periphery of the pellet. CONSTITUTION:A hill-shaped step part 2 higher than an inner periphery at a part or the entire part of the outer periphery of a pellet. For example, a semiconductor pellet is constituted so as to include a semiconductor pellet substrate 3, protruding parts 1 such as electrodes which are formed at the inner pellet part of the substrate, the high hill-shaped step part 2 which is provided at the outer periphery, a sealing resin 4 and a pellet supporting metal plate 5. Metal can be used for said hill-shaped step part 2 in addition to the resin. Even if the shrinkage stress of the resin 4 is generated in the direction of stress from the outer periphery to the inner part as shown by an arrow (a) in resin sealing, the strength of the stress is weakened by the formation of the hill- shaped step 2. Therefore, the effect of the stress into the inner part is less. Thus, breakdown of the vicinity of the protruding parts such as the electrodes 1 in the inner part can be prevented beforehand.

IPC: B21B15/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To drastically improve the joined strength by raising the temp. of each joining surface of a preceding steel slab and the succeeding steel slab in a heating process so as to become the liquidus temp. or higher of the steel slab. SOLUTION: In the case of being the kind of steel containing >=1 wt.% of elements producing oxides having higher m.p. than that of the steel, in at least one of the preceding steel slab S1 and the succeeding steel slab S2, e.g. Cr, Ti, Mn, Al, Si, etc., when each cut end parts of the preceding steel slab S1 and the succeeding steel slab S2 are heated, the temp. of each joining surface of both steel slabs S1, S2 is regulated so as to become the liquidus temp. or higher of the steel slab. In this way, Cr oxide (scale), etc., having the higher m.p. than the m.p. of the steel is exhausted from the joining surface together with the steel becoming the liquid phase after upsetting, and the good continuous rolling can be continued without separating the joined part.  It is desirable that the range for heating to the liquidus or higher of the steel is restrained to <=20% length of the steel slab thickness.
