    • An object of the present invention is to economically produce a resin composition pellet with the degradation of resin suppressed, by using an ordinary extruder, the resin composition pellet being filled with a desired filling amount of a uniformly compounded fibrous filler, and having a required weight average fiber length, in particular, to produce a resin composition pellet used for a socket of a planar socket pin in which the pitch interval of a lattice area of a semiconductor device is 2.0 mm or less, the thickness of the lattice area is 0.5 mm or less, and the height of the socket is 5.0 mm or less. To achieve the object, in supplying 80 to 55% by weight of resin and 20 to 45% by weight of the fibrous filler with a weight average fiber length of 1 mm or more to an extruder to produce a resin composition pellet in which a weight average fiber length of a fibrous filler is 180 to 360 μm, a part of an amount (x) of the resin is supplied through a main feed port of the extruder, and the fibrous filler and a remaining amount (1−x) of the resin are supplied through a side-feed port so that x/(1−x) becomes 50/50 to 10/90% by weight.

    • The object is to provide a method for manufacturing liquid crystalline resin composition having a hollow filler and a fibrous filler using a common melting-kneading extruder to maintain well-balanced relation between the residual percentages of hollow filler and the fiber length, which balance could not be attained in the prior art. A liquid crystalline resin composition having 5 to 30% by weight of hollow filler and 5 to 30% by weight of fibrous filler is manufactured using a melting-kneading extruder provided with a screw. (1) The liquid crystalline resin is fed from a main feed port located at upstream side in the extruding direction, while a hollow filler and a fibrous filler are fed from a side feed port located at downstream side in the extruding direction. The manufacture is conducted under the specific conditions between (2) L1 as the ratio L/D in which D is the screw diameter and L is the distance between the position of the side feed port and the position where the internal pressure of the extruder reaches 0.1 MPa; (3) L2 as the ratio L/D in which D is the screw diameter and L is the length of maintaining the internal pressure of the extruder at or above 0.1 MPa after feeding the hollow filler and the fibrous filler; and (4) La as the ratio L/D in which D is the screw diameter and L is the length of the resin plasticizing zone.

    • A heterojunction bipolar transistor includes a compound semiconductor substrate, a collector layer disposed on the compound semiconductor substrate, a base layer disposed on the collector layer, the base layer being a semiconductor having a band gap energy and including an internal base region and an external base region, and an emitter layer disposed on the base layer and being a semiconductor having a band gap energy larger than the band gap energy of the semiconductor of the base layer. The base layer is larger in area than the emitter layer by the external base region. The external base region is sandwiched by insulating films at the external base region. Therefore, without ion-implantation to make the resistance of the collector layer below the external base region higher, i.e., without increasing the base resistance, the base-collector capacitance is reduced, resulting in an HBT having an improved high frequency gain.
    • 异质结双极晶体管包括化合物半导体衬底,设置在化合物半导体衬底上的集电极层,设置在集电极层上的基极层,基极层是具有带隙能的半导体,并且包括内部基极区域和外部基极 以及设置在基底层上并且具有比基底层的半导体的带隙能量大的带隙能量的半导体的发射极层。 基底层的外部基极区域的面积比发射极层的面积大。 外部基极区域被外部基极区域的绝缘膜夹持。 因此,没有离子注入使得集电极层的电阻在外部基极区域以下更高,即不增加基极电阻,基极集电极电容减小,导致具有改善的高频增益的HBT。
