An inexpensive workpiece holder having high reliability and a processing apparatus equipped with the workpiece holder are provided, in which damage caused by oxygen in the air is prevented. The holder comprises: a ceramic body which has an electrode and a heater circuit and which can holds a workpiece; a tubular member having an end portion connected to the ceramic body; a sealing member which is disposed inside the tubular member and which isolates a space inside the tubular member into two regions: a region on the first end portion (“sealed portion”) and a region on the opposite side (“opposite region”); and power supply conductive members which extend from the opposite region side, penetrating the sealing member to the sealed region side, and which are electrically connected to the electrode and the heater circuit.

A wafer holder less susceptible to deformation even under high load and having high heat-insulating effect and hence capable of improving positional accuracy, improving thermal uniformity and rapid heating and cooling of chips, as well as a heater unit including the wafer holder and a wafer prober including the heater unit are provided. The wafer holder includes a chuck top having a chuck top conductive layer on its surface and a supporter supporting the chuck top, and has a support member in a space between the chuck top and the supporter. Preferably, the support member is arranged concentric with the supporter or approximately at the center of the supporter, and more preferably, support members arranged concentrically and arranged at the center are both provided.

A heater unit that much improves accuracy in thermal uniformity of an object of heating during cooling, particularly rapid cooling, is provided. The heater unit in accordance with the present invention includes a heater substrate for mounting an object of heating and performing heat treatment thereon, and a cooling module for cooling the heater substrate, and between said heater substrate and the cooling module, an intervening body is arranged. Utilizing deformability of the intervening body, ratio of a non-contact portion can be reduced than when the intervening body is not provided, and temperature uniformity of the heater substrate at the time of cooling can be improved.

In the wafer holder in accordance with the present invention, the metal member covers the supporter, preferably apart from the supporter by a distance of at most 5 mm, more preferably at most 1 mm and particularly preferably at most 0.2 mm.
摘要:
The object of the present invention is to prevent damage due to thermal stress induced into a substrate holding table in a substrate holding structure for holding a substrate to be processed. In the substrate holding structure having the substrate holding table arranged at the top of a support column, a flanged part is defined by an inner circumferential surface and an outer circumferential surface at a joint between the support column and the substrate holding table. The inner circumferential surface is formed of an inclined surface, which is inclined such that the inner diameter of the flanged part successively increases as approaching the lower surface of the substrate holding table. On the lower surface of the substrate holding table to which the flanged part is joined, a U-shaped groove is formed so as to correspond to the outer circumferential surface of the flanged part.
摘要:
Joint formations that, in joining together joining members employed in a variety of electrical and electronic components, yield sufficiently high joint strength in the direction perpendicular to the plane in which two joining members join, and meanwhile in the direction parallel to the joint plane. First and second joining members have respective joint phases each formed with a different number of distinct yet continuous conformational faces, defining the joint phases so that neither is the matching complement of the other. A bonding agent interposed between the joint phases joins the joining members together. The difference in thermal expansion coefficient between the two joining members, and between them and the bonding agent, is 5.0×10−6/° C. or less. The joining members are a metal such as tungsten or Cu—W, or a ceramic such as AlN or Si3N4; and glass or a solder material is utilized for the bonding agent.
