Title: Manufacture of resist image
Inventor: KIMINO KAZUYA
IPC: H01L21/027
Filed: 1989-07-07
Abstract: PURPOSE:To obtain a steep inverted resist image in a highly precise manner by a method wherein, after a pattern has been formed on a semiconductor substrate using a mask, a contrast increasing agent is coated, and the adjustment of the angle of the side wall of the pattern is made possible. CONSTITUTION:The first layer of resist 2a and the second layer of resist 2, having different sensitivity with each other, are coated and dried up on a semiconductor substrate 3 in the above-mentioned order. Then, through the intermediary of a mask 1, the resist 2 is exposed using the wavelength to which the resist 2 is sensitive but the resist 2 is not sensitive, developed and a pattern is formed. After a contrast increasing agent 4 has been coated on the above- mentioned pattern, ultraviolet rays 5 to which both resists 2 and 2a are sensitive are projected on the whole surface. By the above-mentioned allover irradiation, a difference in contrast is generated on the thick part and the thin part of the agent 4. At this time, by adjusting the quantity of light of the ultraviolet rays 5, the angle of the side wall of the inversion resist pattern can be adjusted, and a steep inverted resist image can be obtained in a highly precise manner.

Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To allow a user to recognize a caller even when a communication sequence is interrupted on the way by allowing a radio base station to set and send a caller telephone number in an individual station slot upon the receipt of a link channel setup request. SOLUTION: Receiving a link channel setup request message, a control channel control section 120 of a radio base station 100 discriminates whether or not assignment is available and when available, the result is set to an individual station slot and sends it. When not available, the control section 120 allows a timer control section 124 to start time measurement and sends a caller number message after a specified time expires. A control channel control section 140 of a mobile station 104 receives a reject message, the control section 140 informs it to a timer control section 144, which starts time measurement and after time expires, caller number message reception processing is conducted to receive a call number message from the radio base station 100. Thus, even when the communication sequence is interrupted on the way, the user of the mobile station recognizes the caller.

Abstract: PROBLEM TO BE SOLVED: To reduce the influence of crosstalk in bidirectional communication by using the carrier waves of frequencies mutually different responding to the direction of transmission when converting the carrier wave modulated by an electric signal to an optical signal and transmitting it. SOLUTION: The optical signal from an optical high burr 3 is converted to the electric signal by an optic/electric converter 12 and extracted from an output terminal 2' after any desired frequency is extracted by a frequency selection filter 13. The transformed frequency of a frequency transformer 10 at a transmitter/receiver 2 is set to be equal with the selected frequency of the filter 13 at a transmitter/receiver 1. Besides, the transformed frequency of a frequency transformer 4 at the transmitter/receiver 1 is set to be different from the selected frequency of the filter 13. Otherwise, the transformed frequency of the transformer 10 at the transmitter/receiver 2 is set to be different from the selected frequency of a frequency selection filter 9 at the transmitter/ receiver 1.  Thus, power leaked from an input terminal 1 to the output terminal 2' and from an input terminal 2 to an output terminal 1' can be reduced.
