IPC: H01L21/3065
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a pattern-moving process monitoring method in a semiconductor device manufacturing method. SOLUTION: A pattern feature formed on an etched semiconductor layer is installed in the collector 124 of an apparatus 110, such as an electron microscope, and a first amplitude modulation waveform intensity signal is obtained in a controller 132. First amplitude modulation waveform intensity signal is sampled, and the measurement value population of the critical dimension measurement value is extracted. The pattern feature is etched and is re-scanned. A second amplitude modulation waveform intensity signal is obtained and is similarly sampled, and the second measurement value population of the critical dimension measurement value is extracted. The first and second measurement value populations are mutually correlated.  When correct adjustment is executed, when a higher harmonic component appears markedly in the edge part of the pattern feature, for example, it is compared with the known data accumulated in a database 139, the correlation value of etching process is obtained, and the tool 134 can be adjusted.

Title: Speaker and protection circuit for speaker
Inventor: HIRAYAMA KIICHIRO
IPC: H04R1/02
Filed: 2000-08-30
Abstract: PROBLEM TO BE SOLVED: To provide a protection circuit that protects a speaker from its excess input. SOLUTION: A positive characteristic thermistor 11 is inserted to an input line. When an excess input is given to a speaker unit 2, the resistance of the positive characteristic thermistor 11 increases to limit an input signal level given to the speaker unit 2, thereby protecting the speaker from the excess input. Furthermore, the positive characteristic thermistor 11 is fitted to a position taking an air flow flowing around a bass reflex duct 3 into account so as to vary an operating point of the positive characteristic thermistor 11 at which the resistance rapidly increases so as to deactivate the positive characteristic thermistor 11 acting like the protection circuit when a comparatively high current not giving adverse effects onto the speaker flows through the speaker.

Title: Transmission output controller
Inventor: KIN KOJI
IPC: H03G3/30
Filed: 2000-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a transmission output controller which can control transmission outputs without delay with a simple constitution. SOLUTION: When no burst signal is inputted, the transmission output controller supplies a gain control voltage Vref2 which makes a decay rate the maximum to a variable attenuator 1 which supplies the voltage Vref2.
