Title: Bump
Inventor: WATANABE HIROMICHI
IPC: H01L21/60
Filed: 1990-03-16
Abstract: PURPOSE:To exclude imperfect connection with the other connection part, and easily and surely form a tall height bump, by forming a second bump by second transferring, on a first bump electrode formed on an insulative substrate by first transferring. CONSTITUTION:A second bump 8 is formed by second transferring, on a first bump 4 formed on an insulative substrate 1 by first transferring. Hence the second bump 8 can be transferred under the conditions more generous than the first bump 4; that is, at least one of the temperature and the compressive force at the time of transferring can be reduced. As a result, the deformation of the insulative substrate 1 on which the bump is formed and a glass substrate on which a transfer bump has been formed is reduced. Hence the irregularity of the upper surface of the second bump 8 can be made about 1/2 of the irregularity of the upper surface of the first bump 4. Thereby the irregularity of the upper surface of the bump electrode is reduced, imperfect connection with the other connection part is excluded, and a tall bump electrode can easily be formed.

IPC: H01L21/331
Filed: 1989-03-20
Abstract: PURPOSE:To suppress scattering between valleys by causing the difference between the upper end of a valence band in a collector barrier layer and the lower end of a conduction band in a collector layer to be almost equal to or less than the difference between the prescribed valleys. CONSTITUTION:In a heterostructure-bipolar-transistor HBT, there is the difference Es: 0.25eV between the upper end of the valence band in a collector barrier layer 4 and the lower end of a conduction band in a collector layer 3 in such a way that its difference is almost equal to the disorder of a difference Eo: about 0.2eV between a valley L and inverted valley L in the collector barrier layer. Consequently, scattering between valleys in the case of transition of electrons in the above layer 4 is suppressed and then collector layers 2 and 3 are collected without being affected by scattering between the valleys. And, as an i-type GaAsSb layer is used in the layer 4, capacitance between a base and a collector is decreased and it is sufficient to join the collector barrier layer 4, one of the different materials, with the upper part of the collector layer 3 by heterojunction. Scattering between the valleys are thus suppressed in a state that respective layers are left as it is while being laminated.
