Title: Optical attitude matching device
Inventor: KUZE TSUTOMU
IPC: G01B11/00
Filed: 1983-12-28
Abstract: PURPOSE:To execute easily optical attitude matching by placing an optical system whose focal distance is long in the center part and short in the circumferential part, between a photodetector for photodetecting reflected light from an object to be measured, and the object to be measured. CONSTITUTION:Light from a laser oscillator 1 becomes only ''0''-order light by an acoustooptical optical modulator 2, and irradiates an object to be measured 12 through mirrors 3-5, a collimator lens 6, mirrors 9, 10, and a beam splitter 11. The ''0''-order light reflected by the object to be measured 12 is converted in terms of direction by a beam splitter 14, transmits through a perforated lens 15 and is made incident to a position sensor 16. A position error of a sport light on the sensor 16 becomes DELTAx=K.2thetal (l and theta denote a distance between the object to be measured 12 and the sensor 16, an inclination of the object to be measured 12 and the optical axis, respectively). When the inclination is small, the ''0''- order light passes through a hole of the lens and becomes K=1, and when the inclination is large, the ''0''-order light passes through the convex lens part and becomes K<1, and it becomes insensible to an attitude error. In this way, attitude matching by an output of the sensor is executed easily.

Title: Manufacture of resin-sealed semiconductor device
Inventor: UCHIUMI KATSUKI
IPC: H01L23/12
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To prevent defects and failures in a lead and a sealing resin by a method wherein lead cutting is carried out with a rotary blade after a semiconductor device is sealed with resin. SOLUTION: When a resin-sealed semiconductor device is manufactured using a lead frame, the cut part 5 of a lead 4 is cut out with a rotary blade 13 after a resin sealing operation is carried out. Therefore, when the cut part 5 of the lead 4 is cut, a shock caused by the pressure applied at cutting is not applied to the cut part 5, so that lead cutting can be carried out without causing any damage to the leads 4 and a sealing resin 8 around the leads 4. Therefore, defects or failures are prevented from occurring in the leads 4 and the sealing resin 8, and a resin-sealed semiconductor device of high reliability can be obtained. Furthermore, the lead 4 is completely cut off with a blade 13 V-shaped in cross section. By this setup, burrs are restrained from occurring at the cut edge face of the lead 4.

Title: Sample holder for focused ion beam processing
Inventor: MATSUMOTO HIROAKI
IPC: H01J37/30
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To ensure accurate structural analysis of various materials processed by a focused ion beam processing observer by grasping both ends of a processing sample and applying stress such as tensile stress to the sample according to a deformed state of the processing sample. SOLUTION: An ion beam 3 is incident on a sample 1. The sample 1 is mounted by means of a fixing plate 4 and a fixing screw 5 with both ends thereof being grasped. Since both ends of the sample 1 is directly fixed by means of the plate 4 and the screw 5, stress concentration from an unprocessed part to a sample thin film part 2 is prevented, and deformation of the thin film part 2 can be prevented in advance. Therefore, strain to be introduced during sample fabrication can be prevented in advance, and compression to the sample 1 under processing and tensile stress can be applied by moving one side of the sample fixing part, and observation of mode change of materials is made possible.
