Abstract: PURPOSE:To restrain scattering between valleys in a collector barrier, region, and enable high speed operation by forming the collector barrier region by using material whose separation energy between valleys is large as compared with the material of a base region. CONSTITUTION:An emitter barrier region 2 is formed by using I-type semiconductor material, so as to be adjacent to an N-type emitter region 1. An N-type base region 3 is formed so as to be adjacent to the region 2, and further, a collector barrier region 4 and a collector region 5 are formed. The region 4 is constituted of P-type semiconductor material whose separation energy between valleys in the conduction band is large, and the impurity concentration is selected so as to form a specified potential barrier to the region 3. Electron which has passed the region 2 by the effect of tunnel phenomenon enters the region 3. Since the potential of the region 3 is low, the electron is conveyed toward the region 5, The region 4 has been formed by using the material of large separation energy, so that scattering between valleys is restrained, and the decrease of operation speed caused by the scattering between valleys can be prevented.

Title: Method for analyzing semiconductor device failure
Inventor: MURASE MASAMICHI
IPC: G01R31/302
Filed: 1989-02-27
Abstract: PURPOSE:To enable potential of lower wiring to be measured by a method wherein a hole is formed on an insulation film where lower layer conductor wiring and upper layer conductor wiring are laid while electron beam is radiated to a side of the lower layer conductor wiring partially exposed to the surface to measure the potential on this part by an electron beam tester to make analysis. CONSTITUTION:When a semiconductor integrated circuit on a substrate 1 for example formed with aluminum wiring 3 by using silicone nitride films 4 as an interlayer film and a passivation film is to be analyzed, a hole 5 is formed on the silicon nitride film 4 so that a side of the aluminum wiring 3 of a first layer to be analyzed is exposed on the surface by using a focused ion beam (FIB) apparatus. Then electron beam of an electron beam tester using a strobe apparatus is radiated to the substrate 1 from a slant direction so that the beam is incident to the hole 5 while the electron beam is applied to the side of the aluminum wiring 3 of the first layer. This allows the first layer aluminum wiring 3 covered with the second layer aluminum wiring 3 to be measured by potential.

Abstract: PURPOSE:To extract a handwritten character for one character to be the object of character recognition processing. CONSTITUTION:In this handwritten character input device, a tablet control part 100 decides whether an instruction button provided at a pen is instructed or not and when it is decided that the instruction button is instructed, a character recognition managing part 200 judges that a handwritten character is completely inputted just for one character, and executes character recognition processing to the hand written character for one character by activating a character recognition processing part 300. Therefore, since the partition of characters can be detected, a user can input the handwritten character at any arbitrary position on a tablet. Further, since the indication of the instruction part provided at the pen for inputting the handwritten character does not disturb the input of the handwritten character, operability is not damaged.
