A new optical measurement method for detection of slight difference of contact angle has been developed. This new method is applied to detect the micro blemish of self assembled monolayers (SAMs) because the blemished SAMs causes slight difference of contact angle from that of normal SAMs. In this method, a test plate is preliminarily set up at a tilt angle, which is same as the contact angle of normal SAMs. This setting forms a very small two-dimensional meniscus near the plate depending on the contact angle difference between blemished SAMs and normal SAMs. When a laser beam is emitted to the meniscus from above, the incident laser beam is reflected at a certain angle depending on the inclined angle of the liquid surface formed by the meniscus. In consequence, the contact angle difference is measured based on the reflection angle of the laser beam. This method is capable of detecting slight angle difference under 1 degree between blemished SAMs and normal SAMs.
