Patent JP-S6310531-A (JP)
Title: Treatment method
Inventor: MAEDA YORIHISA
IPC: H01L21/306
Filed: 1986-07-02
Abstract: PURPOSE:To evenly treat objects like wafers in a short time regardless of the surface feature of the objects, by applying ultrasonic energy to the objects while treating fluid that adheres to the objects is removed after a pressure in a container returns to an atmospheric pressure. CONSTITUTION:Ultrasonic energy is applied over objects to be treated until treating fluid is removed. For example, Si wafers having a 4mum-deep trench formed by etching are put in a storage case 14a and a low pressure container 11 is sealed after cleaning solution having a volumetric proportion of NH4OH:H2 O2:H2O=1:2:8 at 70 deg.C are poured in a vessel 12 made of quartz. After that, the Si wafers 17 are immensed completely into the cleaning solution 15 by pressing a pinching jig 14b of the storage case 14a. And then, the ultrasonic energy (40 KHz, 300W) is applied and while reducing the pressure by using a rotary pump 13, the low pressure container 11 permits the storage case 14a to rotate 4 or 5 times in the solution 15 by making the pinching jig 14b turn round and as soon as the pressure of low pressure container 11 returns to an atmospheric pressure by introducing air into the container 11 after cracking a valve 16, the ultrasonic energy is applied.
