A structure for connecting fluid channel of fluid delivery system is disclosed. This connecting structure limits the length of the flow-guiding pipe extending into the delivery channel, to reduce particle contaminates and the probability of crack. The present pipe union connecting structure comprises a first pipe, a second pipe mounted to the first pipe, and an inner pipe extending from the first pipe into the second pipe with a certain extending length. The extending length of the inner pipe is less than the proportion of the minimum distance between the inner wall of the second pipe and the outlet of the inner pipe when standstill, to the tangent value of a certain angle &thgr;, which is the maximum inclined angle between the second pipe and the inner pipe.

A clamp used in clamping semi-conductor wafers during processing operations permits ready release of the wafer and avoids adherence of the clamp to materials deposited onto the wafer which otherwise tend to stick the wafer to the clamp. Adhesion of the deposited materials to the clamp is avoided by providing the clamping surfaces of the clamp with a minimum surface roughness achieved by machining, grinding, etching or other techniques.

The present invention provides a method and a set of trimming accessories for trimming rubber plate used in an ion implanter. The rubber plate is suitable for use in an ion implanter, wherein the ion implanter has a platform with multiple primary holes and multiple primary notches. In specific embodiments, the set of trimming accessories includes trimming equipment such as a knife or preferably a laser; a template with secondary holes corresponding to primary holes and secondary notches corresponding to primary notches. The template is used as a guide to form a plurality of tertiary holes in the rubber plate corresponding to the plurality of secondary holes of the template and to form a plurality of tertiary notches in the rubber plate corresponding to the plurality of secondary notches of the template. The trimmed rubber plate can then be placed on the platform so that the tertiary holes of the rubber plate match the primary holes of the platform and the tertiary notches of the rubber plate match the primary notches of the platform.

A wafer load/unload apparatus used to load/unload the wafer into/from the clamp ring for performing the E-Gun evaporation process is disclosed. The apparatus comprises a base, a central cylinder and a plurality of peripheral cylinders. The base has an even upper surface, and the central cylinder and the plurality of the peripheral cylinders are connected to the upper surface of the base respectively, wherein the plurality of the peripheral cylinders are located around the central cylinders. A recessed trench penetrating through sidewalls of the central cylinder is formed on a top surface of the central cylinder. The central cylinder can penetrate through a clamp ring, wherein the clamp ring is used to load a wafer for performing the E-Gun evaporating process. The spacing distances between the plurality of peripheral cylinders and the central cylinder are bigger than the width of the clamp ring. The plurality of peripheral cylinders are used to prevent the wafer which is placed on the top surface of the central cylinder from falling down.
