Problems solved by technology

However, in this case, the outer peripheral portion or central portion of the substrate may be subjected to excessive heat treatment
That is, in the conventional heat treatment apparatus, it is difficult to heat treat the substrate in a short time and uniformly heat treat the entire surface of the substrate.

Abstract

The invention provides a hot treatment device and method, which can uniformly carry out a hot treatment on the whole surface of a substrate in a short time. The hot treatment device (1) has a plurality of elevating pins (51) for supporting the periphery (91) of a substrate (9); and a plurality of second evaluating pins (52) for supporting the center (92) of the substrate (9). A temperature mechanism (40) raises the temperature of a hot treatment plate (30) until the central area of the hot treatment plate (30) is higher than the target temperature. After the hot treatment is started and the center (92) of the substrate (9) reaches the target temperature, the control part (80) drives the elevating mechanism (60) to elevate the second elevating pins (52) so as to separate the center (92) of the substrate (9) from the hot treatment plate (30). Thus, the center (92) of the substrate (9) is taken as the baseline, and the whole surface of the substrate (9) can be uniformly and thermally processed in a short time.

Description

technical field [0001] The present invention relates to a heat treatment device and a heat treatment method for cooling or heating a substrate to a target temperature. Background technique [0002] In the past, precision electronic devices such as semiconductor wafers, glass substrates for liquid crystal display devices, glass substrates for PDPs, glass substrates for photomasks, substrates for color filters, substrates for recording disks, substrates for solar cells, and substrates for e-books In the manufacturing process of the substrate, a heat treatment apparatus for cooling or heating the substrate is used. The heat treatment apparatus is used, for example, in a step of curing a processing liquid such as a photoresist applied on a substrate, and a step of drying a cleaned substrate. [0003] For example, Patent Documents 1 and 2 describe conventional heat treatment apparatuses. Patent Document 1 describes a substrate temperature adjustment unit that adjusts the temper...
