Title: Manufacture of semiconductor device and manufacturing apparatus of the device
Inventor: NISHINO HIROTAKE
IPC: H01L21/306
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To subject an object wet treatment of a strong oxidative power and remove, in a short time, the peeled pieces of an organic thin film, such as a resist, and a contaminated organic matter and the like, which are adhering to the surface of a wafer by a method, wherein light of a wavelength shorter than a specified value is irradiated on the surface of the substrate exposed to a gas or a liquid containing hydrogen peroxide. SOLUTION: A silicon wafer, removed of an organic matter and a metal film on its surface, is left in a clean room for a week. Thereafter, the wafer is put on a sample board 103 in a treatment vessel 101. Then heated water hydrogen peroxide is bubbled with argon gas, and while the gas hydrogen peroxide is introduced in the container 101 through a gas inlet port 105, the wafer is irradiated with a light (wavelength of 253.7 nm) of a mercury lamp for one minute. While the wafer is exposed to gas hydrogen peroxide, the wafer is irradiated with ultraviolet rays, but even though hydrogen peroxide is a liquid state, it absorbs light of wavelength of about 300 nm or shorter and is decomposed by the light, when the light is irradiated on the wafer.  Therefore, even if UV light is irradiated on the wafer in a state in which the wafer is immersed in a solution containing hydrogen peroxide, a contaminated organic matter and the like on the surface of the wafer can be removed.

IPC: G01C19/5762
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To ensure stabilized resonance regardless of the shaking voltage by damping interference of an applying voltage with a shaking comb driver through an asymmetric comb sensor. SOLUTION: A beam resilient body 130 placed between inner and outer frames 110, 120 detects oscillation in the sensing direction due to Coriolis force based on the difference of capacitance between a sensing electrode 170 and a comb 150 when the inner frame 110 oscillates in the sensing direction (Y axis). The outer frame 120 is shaken with an electrostatic force generated between shaking comb drivers 250, 250' and a plurality of frame section shaking combs 220 shakable in the shaking direction (X axis) provided on the outside of the outer frame 120. Asymmetric comb sensors 270, 270' for sensing the oscillation in the shaking direction cancels the interference shaking voltage of a signal transmitted through the outer frame 120 with a shaking voltage when the shaking combs 220 are shaken through the shaking comb drivers 250, 250'.  Consequently, the effect of interference can be eliminated.
