Title: Imaging system and its operating method
Inventor: RICHARD JUNG CHAO
IPC: G06T1/00
Filed: 2000-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a system and method for imaging blood flow and contrast media. SOLUTION: When flow imaging is effected using coded excitation and wall filter process, a series of coded broad-band pulses (about a fundamental frequency) is transmitted a number of times to a specific transmission focal position. Each coded series constitutes one firing. During reception, received signals acquired as to each firing are supplied to a finite impulse response filter 48 compressing the received pulses and performing band-pass filter process, and, e.g. compressed pulses about the fundamental frequency, are separated. Next, the signals compressed and separated are subjected to high-pass filter process over plural firings by use of a wall filter. Using the signals subjected to wall filter process, blood flow and contrast media are imaged.

Title: Method for manufacturing semiconductor device
Inventor: INOUE KOICHIRO
IPC: H01L29/78
Filed: 2000-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device capable of suppressing deterioration or variance of electrical characteristics of a MOS transistor and improving a yield. SOLUTION: The surface of a silicon substrate 11 is not oxidized or an oxide film remaining on the substrate is removed, for example, by using a dilute fluoric acid, just before a channel ion implantation or an ion implantation, for forming a source, drain regions, and then ions are implanted. In this case, since the ion implantation of the impurity is conducted in a state in which an oxygen remaining on the surface of the substrate is removed, a concentration of the contained oxygen is small. Then, an impurity region with a small impurity concentration distribution variance due to non uniform sacrificing oxide film thickness can be formed. Thus, a trouble caused by the ion implantation of the impurity via the sacrificing oxide film for protecting the surface of the substrate can be solved.
