Title: Wax for compound semiconductor wafer
Inventor: INADA TOMOKI
IPC: H01L21/304
Filed: 1991-11-06
Abstract: PURPOSE:To permit wax to contain lubricant which does not electrically influence a GaAs compound semiconductor wafer when the wafer is contaminated instead of using Zn. CONSTITUTION:Compound semiconductor wafer wax is used for sticking a wafer on a jig to process and protecting the front or rear plane of the wafer. As for the wax, resin which softens at 45 deg.C is melted into acetone. Tens- thousands ppm of Ga, which is one of the elements that constitute GaAs compound semiconductor, is added to the wax as lubricant instead of Zn. An element to add as the lubricant is permitted to be group element as Ga or group V element as As and one of the two elements is added or the both are simultaneously added. Thus, even when the GaAs compound semiconductor wafer is contaminated by polishing, since the contamination source, the lubricant such as Ga, becomes electrically neutral, the electric characteristic is not changed.

Title: Production of blocked urine group-containing polyisocyanate
Inventor: RAINERU GURAASU
IPC: C07C275/26
Filed: 1988-11-18
Abstract: Direct reaction of polyisocyanates and polyamines occurs vigorously and uncontrollably. It is therefore necessary to use the polyisocyanate in blocked form. In previously known processes, it has not been possible to obtain the desired semi-blocked adducts; instead, relatively large portions of completely blocked product in addition to unreacted polyisocyanate were obtained. The further reaction with polyamines was unsuccessful. 
<??>The preparation of blocked, urea-containing polyisocyanates has been made possible by using semi-blocked polyisocyanates, which are formed by the addition of blocking agent to a manifold excess of polyisocyanate, followed by thin-film distillation and subsequent reaction with polyamines in an NCO/amino group ratio of 1 to 1.3:1 to 1.1. 
<??>The blocked, urea-containing polyisocyanates are used in particular for PUR paints.
