    In general, when the temperature goes down, gas becomes liquid and liquid becomes solid, and the viscosity of matter increases.

    The gas used in manufacturing semiconductors also coagulates when cooled, and clogs up the pipes in the manufacturing device. Kawai Corporation's heaters are used in the situation to prevent clogging.

    It should be quite obvious that products cannot be normally manufactured when the pipes clog up. Our mission with pipe heaters at Kawai Corporation is to ensure that whatever the outer environment might be, manufacturing must go on. We design these heaters so that our customers do not need to worry about controlling the external temperature.

    It's easy just to heat things up, but what is required is highly accurate, even heating. In one case, we asked our customer to provide us with the same pipe used in the actual device, after which we made a prototype heater and did some tests with the pipe attached. From this, we collected data and determined where the temperature dropped due to large heat dispersion, as well as where heat collected. By running some more tests, we finally created what we thought was the perfect heater.

    However, when we tried to actually attach the pipe onto the customer's device, it got in the way of other parts, so we had to try again. At that point, we had only three weeks left before the heater was to be delivered.

    Here's where Kawai Corporation rose to the challenge! After redesigning the product, we did some fine-tuning with the customer's actual device in terms of how it was used, and delivered the completed product on schedule. In the end, the evenness of heating went beyond the customer's expectations.

    The fact that we go to the customer to confirm the actual device, and then design and install our products makes this all possible.

    In the semiconductor manufacturing industry in particular, not all of the specifications are decided upon before manufacturing. It's not uncommon for the specs of the device on which the heater will be used to remain undecided. It's difficult to deal with frequently-changing specs and deliver on time, but Kawai Corporation handles changes in specs on the fly and rigidly sticks to the delivery date.

    In recent years, the demands for heat treatment of wafers within the semiconductor industry have been more and more stringent. As a vendor of heating devices, Kawai Corporation has been coming up with many ideas and making efforts to meet these demands.

    For example, in cases where the customer wanted to preheat with a heater in order to realize rapid heating or cooling of several dozen degrees C on a linear gradient, or to maintain a uniform temperature within a margin of several degrees C, we have selected the ET-600 due to the high temperature required and the shape.

    Although the ET-600 is a superb planar heater that can handle very high temperatures, there are other factors to consider such as thermal expansion and methods of use.

    In order to propose a set of dimensions and a shape that would accommodate thermal expansion, we performed many internal tests by taking temperature data using prototype heaters, while giving our opinions on the device's construction. Finally, we delivered this data and our observations along with the finished heater to the customer. Kawai Corporation's strengths are in performing tests with the customers to create the very best product. That said, the thing that makes this process even stronger is the speed at which we do it, as well as how we work with partner companies.

    Our customer evaluated us highly for how we not only collected data, but for how we made observations and created a proposal using the conclusions we arrived at, including the temperature controller (manufactured by our partner company Azbil North America)... not to mention the speed at which we made the proposals. All of this resulted in Kawai Corporation earning great satisfaction from our client, and in our own satisfaction in being of assistance.
