摘要: Provided is a method of fabricating a heterojunction bipolar transistor (HBT). The method includes: sequentially depositing a sub-collector layer, a collector layer, a base layer, an emitter layer, and an emitter capping layer on a substrate; forming an emitter electrode on the emitter capping layer; forming a mesa type emitter to expose the base layer by sequentially etching the emitter capping layer and the emitter layer using the emitter electrode as an etch mask in vertical and negative-sloped directions to the substrate, respectively; and forming a base electrode on the exposed base layer using the emitter electrode as a mask in self-alignment with the emitter electrode. In this method, a distance between the mesa type emitter and the base electrode can be minimized and reproducibly controlled. Also, a self-aligned device with an excellent high-frequency characteristic can be embodied.

摘要: Provided are a chip, a chip stack, and a method of manufacturing the same. A plurality of chips which each include: at least one pad formed on a wafer; and a metal layer which protrudes up to a predetermined thickness from the bottom of the wafer and is formed in a via hole exposing the bottom of the pad are stacked such that the pad and the metal layer of adjacent chips are bonded. This leads to a simplified manufacturing process, high chip performance and a small footprint for a chip stack.

摘要: A test device includes: a testing unit connected with a measurement line, and configured to apply bias to the measurement line and measure the measurement line; a plurality of switching units configured to electrically connect the measurement line and the plurality of samples; and a control unit configured to sequentially turn on the plurality of switching units to sequentially apply the bias to the plurality of samples. The control unit determines whether a corresponding device sample has a defect based on a first measurement value according to measurement by the testing unit when the bias is applied to each of the plurality of samples.
