A manufacture method of a latent heat recovery type heat exchanger. A plurality of heat absorbing snake pipes is provied in a body for flowing combustion discharging air. One end of the heat absorbing pipes is connected to an inflow assemble and the other end is connected to an outflow assemble so that the fluid to be heated can flow to the outflow assemble from the inflow assemble via the heat absorbing pipes. Thus, it is possible to manufacture a latent heat recovery type heat exchanger for recovering a latent heat in a cost as low as possible by coagulating the water vapour of the combustion discharging air outside the absorbing pipes and then recovering the latent heat. One and the other end of the plurality of the heat absorbing snake pipes are inserted into the inflow assemble (421), the outflow assemble (422), respectively, after assembled, an auxiliary assembling device is then thrown into a furnace to perform soldering in a furnace for soldering each end of the absorbing pipes (41) on the inflow assemble (421, 422). In addition, heat treatment is implemented in the furnace braze soldering process to remove the residual stress from the absorbing pipes (41).

A motor-driven supercharger is provided with a thrust bearing (30) rotatably supporting a thrust force applied to a turbine shaft (12). The thrust bearing (30) is constituted by a small-diameter disc-shaped thrust collar (32) rotating together with a turbine shaft, and a turbine side thrust bearing (34) and a compressor side thrust bearing (36) which block a movement in an axial direction of the thrust collar. The compressor side thrust bearing (36) has a small-diameter ring portion (37) including a thrust surface which is in contact with the thrust collar and has approximately an equal diameter, and a flange portion (38a) fixed to a housing (16) in the turbine side, and the small-diameter ring portion and the flange portion are arranged at different positions in an axial direction.

Material is removed from a substrate surface (e.g., from a bottom portion of a recessed feature on a partially fabricated semiconductor substrate) by subjecting the surface to a plurality of profiling cycles, wherein each profiling cycle includes a net etching operation and a net depositing operation. An etching operation removes a greater amount of material than is being deposited by a depositing operation, thereby resulting in a net material etch-back per profiling cycle. About 2-10 profiling cycles are performed. The profiling cycles are used for removing metal-containing materials, such as diffusion barrier materials, copper line materials, and metal seed materials by PVD deposition and resputter. Profiling with a plurality of cycles removes metal-containing materials without causing microtrenching in an exposed dielectric. Further, overhang is reduced at the openings of the recessed features and sidewall material coverage is improved. Integrated circuit devices having higher reliability are fabricated.
